• CastClassException on Custom View

  - by tuxGurl

  When I try to findViewById() on my custom view I keep getting a ClassCastException. I've tried so many things that I'm sure I've botched the code now! To make sure I'm not going insane I stripped down the classes to their bare minimum inorder to find what was wrong. I'm new to android programming and I'm sure I'm missing something basic. This is BaseImageView an extended view class. package com.company.product.client.android.gui.views; import android.content.Context; import android.graphics.Canvas; import android.graphics.Color; import android.view.View; public class BaseImageView extends View { public BaseImageView(Context context) { super(context); } @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); canvas.drawColor(Color.GREEN); } } This is LiveImageView an extension of the BaseImageView class. package com.company.product.client.android.gui.views; import android.content.Context; import android.util.AttributeSet; public class LiveImageView extends BaseImageView { public LiveImageView(Context context, AttributeSet attrs) { super(context); } } Here is the Layout my_view.xml. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center"> <View class="com.company.product.client.android.gui.views.LiveImageView" android:id="@+id/lvImage" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> And here is the onCreate in my Activity LiveViewActivity. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); try { setContentView(R.layout.my_view); final LiveImageView lvImage = (LiveImageView) findViewById(R.id.lvImage); } catch (final Exception e) { Log.e(TAG, "onCreate() Exception: " + e.toString()); e.printStackTrace(); } Finally, this is stack trace. 02-11 17:25:24.829: ERROR/LiveViewActivity(1942): onCreate() Exception: java.lang.ClassCastException: android.view.View 02-11 17:25:24.839: WARN/System.err(1942): java.lang.ClassCastException: android.view.View 02-11 17:25:24.839: WARN/System.err(1942): at com.company.product.client.android.gui.screen.LiveViewActivity.onCreate(LiveViewActivity.java:26) 02-11 17:25:24.839: WARN/System.err(1942): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 02-11 17:25:24.849: WARN/System.err(1942): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2459) 02-11 17:25:24.849: WARN/System.err(1942): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2512) 02-11 17:25:24.849: WARN/System.err(1942): at android.app.ActivityThread.access$2200(ActivityThread.java:119) 02-11 17:25:24.849: WARN/System.err(1942): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1863) 02-11 17:25:24.859: WARN/System.err(1942): at android.os.Handler.dispatchMessage(Handler.java:99) 02-11 17:25:24.859: WARN/System.err(1942): at android.os.Looper.loop(Looper.java:123) 02-11 17:25:24.859: WARN/System.err(1942): at android.app.ActivityThread.main(ActivityThread.java:4363) 02-11 17:25:24.869: WARN/System.err(1942): at java.lang.reflect.Method.invokeNative(Native Method) 02-11 17:25:24.869: WARN/System.err(1942): at java.lang.reflect.Method.invoke(Method.java:521) 02-11 17:25:24.869: WARN/System.err(1942): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 02-11 17:25:24.869: WARN/System.err(1942): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 02-11 17:25:24.879: WARN/System.err(1942): at dalvik.system.NativeStart.main(Native Method)

• Trouble with detecting gestures over ListView

  - by Andrew

  I have an Activity that contains a ViewFlipper. The ViewFlipper includes 2 layouts, both of which are essentially just ListViews. So the idea here is that I have two lists and to navigate from one to the other I would use a horizontal swipe. I have that working. However, what ever list item your finger is on when the swipe begins executing, that item will also be long-clicked. Here is the relevant code I have: public class MyActivity extends Activity implements OnItemClickListener, OnClickListener { private static final int SWIPE_MIN_DISTANCE = 120; private static final int SWIPE_MAX_OFF_PATH = 250; private static final int SWIPE_THRESHOLD_VELOCITY = 200; private GestureDetector mGestureDetector; View.OnTouchListener mGestureListener; class MyGestureDetector extends SimpleOnGestureListener { @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { try { if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) return false; // right to left swipe if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { if (mCurrentScreen != SCREEN_SECONDLIST) { mCurrentScreen = SCREEN_SECONDLIST; mFlipper.setInAnimation(inFromRightAnimation()); mFlipper.setOutAnimation(outToLeftAnimation()); mFlipper.showNext(); updateNavigationBar(); } } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { if (mCurrentScreen != SCREEN_FIRSTLIST) { mCurrentScreen = SCREEN_FIRSTLIST; mFlipper.setInAnimation(inFromLeftAnimation()); mFlipper.setOutAnimation(outToRightAnimation()); mFlipper.showPrevious(); updateNavigationBar(); } } } catch (Exception e) { // nothing } return true; } } @Override public boolean onTouchEvent(MotionEvent event) { if (mGestureDetector.onTouchEvent(event)) return true; else return false; } ViewFlipper mFlipper; private int mCurrentScreen = SCREEN_FIRSTLIST; private ListView mList1; private ListView mList2; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.layout_flipper); mFlipper = (ViewFlipper) findViewById(R.id.flipper); mGestureDetector = new GestureDetector(new MyGestureDetector()); mGestureListener = new View.OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (mGestureDetector.onTouchEvent(event)) { return true; } return false; } }; // set up List1 screen mList1List = (ListView)findViewById(R.id.list1); mList1List.setOnItemClickListener(this); mList1List.setOnTouchListener(mGestureListener); // set up List2 screen mList2List = (ListView)findViewById(R.id.list2); mList2List.setOnItemClickListener(this); mList2List.setOnTouchListener(mGestureListener); } … } If I change the "return true;" statement from the GestureDetector to "return false;", I do not get long-clicks. Unfortunately, I get regular clicks. Does anyone know how I can get around this?

• AES Cipher not picking up IV

  - by timothyjc

  I am trying to use an IV with AES so that the encrypted text is unpredictable. However, the encrypted hex string is always the same. I have actually tried a few methods of attempting to add some randomness by passing some additional parameters to the cipher init call: 1) Manual IV generation byte[] iv = generateIv(); IvParameterSpec ivspec = new IvParameterSpec(iv); 2) Asking cipher to generate IV AlgorithmParameters params = cipher.getParameters(); params.getParameterSpec(IvParameterSpec.class); 3) Using a PBEParameterSpec byte[] encryptionSalt = generateSalt(); PBEParameterSpec pbeParamSpec = new PBEParameterSpec(encryptionSalt, 1000); All of these seem to have no influence on the encrypted text.... help!!! My code: package com.citc.testencryption; import java.security.NoSuchAlgorithmException; import java.security.SecureRandom; import javax.crypto.Cipher; import javax.crypto.SecretKey; import javax.crypto.SecretKeyFactory; import javax.crypto.spec.IvParameterSpec; import javax.crypto.spec.PBEKeySpec; import android.app.Activity; import android.os.Bundle; import android.util.Log; public class Main extends Activity { public static final int SALT_LENGTH = 20; public static final int PBE_ITERATION_COUNT = 1000; private static final String RANDOM_ALGORITHM = "SHA1PRNG"; private static final String PBE_ALGORITHM = "PBEWithSHA256And256BitAES-CBC-BC"; private static final String CIPHER_ALGORITHM = "PBEWithSHA256And256BitAES-CBC-BC"; private static final String TAG = Main.class.getSimpleName(); @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); try { String password = "password"; String plainText = "plaintext message to be encrypted"; // byte[] salt = generateSalt(); byte[] salt = "dfghjklpoiuytgftgyhj".getBytes(); Log.i(TAG, "Salt: " + salt.length + " " + HexEncoder.toHex(salt)); PBEKeySpec pbeKeySpec = new PBEKeySpec(password.toCharArray(), salt, PBE_ITERATION_COUNT); SecretKeyFactory keyFac = SecretKeyFactory.getInstance(PBE_ALGORITHM); SecretKey secretKey = keyFac.generateSecret(pbeKeySpec); byte[] key = secretKey.getEncoded(); Log.i(TAG, "Key: " + HexEncoder.toHex(key)); // PBEParameterSpec pbeParamSpec = new PBEParameterSpec(salt, ITERATION_COUNT); Cipher encryptionCipher = Cipher.getInstance(CIPHER_ALGORITHM); // byte[] encryptionSalt = generateSalt(); // Log.i(TAG, "Encrypted Salt: " + encryptionSalt.length + " " + HexEncoder.toHex(encryptionSalt)); // PBEParameterSpec pbeParamSpec = new PBEParameterSpec(encryptionSalt, 1000); // byte[] iv = params.getParameterSpec(IvParameterSpec.class).getIV(); // Log.i(TAG, encryptionCipher.getParameters() + " "); byte[] iv = generateIv(); IvParameterSpec ivspec = new IvParameterSpec(iv); encryptionCipher.init(Cipher.ENCRYPT_MODE, secretKey, ivspec); byte[] encryptedText = encryptionCipher.doFinal(plainText.getBytes()); Log.i(TAG, "Encrypted: " + HexEncoder.toHex(encryptedText)); // <== Why is this always the same :( Cipher decryptionCipher = Cipher.getInstance(CIPHER_ALGORITHM); decryptionCipher.init(Cipher.DECRYPT_MODE, secretKey, ivspec); byte[] decryptedText = decryptionCipher.doFinal(encryptedText); Log.i(TAG, "Decrypted: " + new String(decryptedText)); } catch (Exception e) { e.printStackTrace(); } } private byte[] generateSalt() throws NoSuchAlgorithmException { SecureRandom random = SecureRandom.getInstance(RANDOM_ALGORITHM); byte[] salt = new byte[SALT_LENGTH]; random.nextBytes(salt); return salt; } private byte[] generateIv() throws NoSuchAlgorithmException { SecureRandom random = SecureRandom.getInstance(RANDOM_ALGORITHM); byte[] iv = new byte[16]; random.nextBytes(iv); return iv; } }

• Action bar with Search View. Reverse compatibility issues

  - by suresh

  I am building a sample app to demonstrate SearchView with filter and other Action Bar items. I am able to successfully run this app on 4.2(Nexus 7). But it is not running on 2.3. I googled about the issue. Came to know that i should use SherLock Action bar. I just went to http://actionbarsherlock.com/download.html, downloaded the zip file and added the library as informed in the video: http://www.youtube.com/watch?v=4GJ6yY1lNNY&feature=player_embedde by WiseManDesigns. But still I am unable to figure out the issue. Here is my code: SearchViewActionBar.java public class SearchViewActionBar extends Activity implements SearchView.OnQueryTextListener { private SearchView mSearchView; private TextView mStatusView; int mSortMode = -1; private ListView mListView; private ArrayAdapter<String> mAdapter; protected CharSequence[] _options = { "Wild Life", "River", "Hill Station", "Temple", "Bird Sanctuary", "Hill", "Amusement Park"}; protected boolean[] _selections = new boolean[ _options.length ]; private final String[] mStrings = Cheeses.sCheeseStrings; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); getWindow().requestFeature(Window.FEATURE_ACTION_BAR); setContentView(R.layout.activity_main); // mStatusView = (TextView) findViewById(R.id.status_text); // mSearchView = (SearchView) findViewById(R.id.search_view); mListView = (ListView) findViewById(R.id.list_view); mListView.setAdapter(mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mStrings)); mListView.setTextFilterEnabled(true); //setupSearchView(); } private void setupSearchView() { mSearchView.setIconifiedByDefault(true); mSearchView.setOnQueryTextListener(this); mSearchView.setSubmitButtonEnabled(false); //mSearchView.setQueryHint(getString(R.string.cheese_hunt_hint)); } @Override public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.searchview_in_menu, menu); MenuItem searchItem = menu.findItem(R.id.action_search); mSearchView = (SearchView) searchItem.getActionView(); //setupSearchView(searchItem); setupSearchView(); return true; } @Override public boolean onPrepareOptionsMenu(Menu menu) { if (mSortMode != -1) { Drawable icon = menu.findItem(mSortMode).getIcon(); menu.findItem(R.id.action_sort).setIcon(icon); } return super.onPrepareOptionsMenu(menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { String c="Category"; String s=(String) item.getTitle(); if(s.equals(c)) { System.out.println("same"); showDialog( 0 ); } //System.out.println(s); Toast.makeText(this, "Selected Item: " + item.getTitle(), Toast.LENGTH_SHORT).show(); return true; } protected Dialog onCreateDialog( int id ) { return new AlertDialog.Builder( this ) .setTitle( "Category" ) .setMultiChoiceItems( _options, _selections, new DialogSelectionClickHandler() ) .setPositiveButton( "SAVE", new DialogButtonClickHandler() ) .create(); } public class DialogSelectionClickHandler implements DialogInterface.OnMultiChoiceClickListener { public void onClick( DialogInterface dialog, int clicked, boolean selected ) { Log.i( "ME", _options[ clicked ] + " selected: " + selected ); } } public class DialogButtonClickHandler implements DialogInterface.OnClickListener { public void onClick( DialogInterface dialog, int clicked ) { switch( clicked ) { case DialogInterface.BUTTON_POSITIVE: printSelectedPlanets(); break; } } } protected void printSelectedPlanets() { for( int i = 0; i < _options.length; i++ ){ Log.i( "ME", _options[ i ] + " selected: " + _selections[i] ); } } public void onSort(MenuItem item) { mSortMode = item.getItemId(); invalidateOptionsMenu(); } public boolean onQueryTextChange(String newText) { if (TextUtils.isEmpty(newText)) { mListView.clearTextFilter(); } else { mListView.setFilterText(newText.toString()); } return true; } public boolean onQueryTextSubmit(String query) { mStatusView.setText("Query = " + query + " : submitted"); return false; } public boolean onClose() { mStatusView.setText("Closed!"); return false; } protected boolean isAlwaysExpanded() { return false; } }

• Duplication of menu items with ViewPager and Fragments

  - by Julian

  I'm building an Android Application (minimum SDK Level 10, Gingerbread 2.3.3) with some Fragments in a ViewPager. I'm using ActionBarSherlock to create an ActionBar and android-viewpagertabs to add tabs to the ViewPager just like in the Market client. I have one global menu item that I want to be shown on every tab/fragment. On the first of the three tabs I want to have two additional menu items. But now two strange things happen: First if I start the app, everything seems to be fine, I can see all three menu items on the first page and only one item if i swipe to the second and third tab. But if I swipe back to the second tab from the third one, I can see all three items again which shouldn't happen. If I swipe back to the first and then again to the second tab, everything is fine again. The other strange thing is that every time I rotate the device, the menu items from the fragment are added again, even though they are already in the menu. Code of the FragmentActivity that displays the ViewPager and its tabs: public class MainActivity extends FragmentActivity { public static final String TAG = "MainActivity"; private ActionBar actionBar; private Adapter adapter; private ViewPager viewPager; private ViewPagerTabs tabs; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.volksempfaenger); actionBar = getSupportActionBar(); adapter = new Adapter(getSupportFragmentManager()); adapter.addFragment(getString(R.string.title_tab_subscriptions), SubscriptionGridFragment.class); // adding more fragments here viewPager = (ViewPager) findViewById(R.id.viewpager); viewPager.setAdapter(adapter); tabs = (ViewPagerTabs) findViewById(R.id.tabs); tabs.setViewPager(viewPager); } public static class Adapter extends FragmentPagerAdapter implements ViewPagerTabProvider { private FragmentManager fragmentManager; private ArrayList<Class<? extends Fragment>> fragments; private ArrayList<String> titles; public Adapter(FragmentManager fm) { super(fm); fragmentManager = fm; fragments = new ArrayList<Class<? extends Fragment>>(); titles = new ArrayList<String>(); } public void addFragment(String title, Class<? extends Fragment> fragment) { titles.add(title); fragments.add(fragment); } @Override public int getCount() { return fragments.size(); } public String getTitle(int position) { return titles.get(position); } @Override public Fragment getItem(int position) { try { return fragments.get(position).newInstance(); } catch (InstantiationException e) { Log.wtf(TAG, e); } catch (IllegalAccessException e) { Log.wtf(TAG, e); } return null; } @Override public Object instantiateItem(View container, int position) { FragmentTransaction fragmentTransaction = fragmentManager .beginTransaction(); Fragment f = getItem(position); fragmentTransaction.add(container.getId(), f); fragmentTransaction.commit(); return f; } } @Override public boolean onCreateOptionsMenu(Menu menu) { BaseActivity.addGlobalMenu(this, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { return BaseActivity.handleGlobalMenu(this, item); } } Code of the fragment that shall have its own menu items: public class SubscriptionGridFragment extends Fragment { private GridView subscriptionList; private SubscriptionListAdapter adapter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setHasOptionsMenu(true); } // ... @Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { inflater.inflate(R.menu.subscription_list, menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { // ... } }

  hi, i have written a simple app which would speak out to the user any incoming message. Both programmes seem to work perfectly when i lauched them as two separate pgms , but on keeping them in the same project/package only the speaker programme screen is seen and the receiver pgm doesn't seem to work . Can someone please help me out on it? the speaker pgm is: package com.example.TextSpeaker; import java.util.Locale; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.speech.tts.TextToSpeech; import android.speech.tts.TextToSpeech.OnInitListener; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.Toast; // the following programme converts the msg user to speech public class TextSpeaker extends Activity implements OnInitListener { /** Called when the activity is first created. */ int MY_DATA_CHECK_CODE = 0; public TextToSpeech mtts; public Button button; //public EditText edittext; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); button = (Button)findViewById(R.id.button); //edit text=(EditText)findViewById(R.id.edittext); button.setOnClickListener(new OnClickListener(){ @Override public void onClick(View v) { //mtts.speak(edittext.getText().toString(), TextToSpeech.QUEUE_FLUSH, null); Toast.makeText(getApplicationContext(), "The service has been started\n Every new message will now be read out", Toast.LENGTH_LONG).show(); } }); Intent myintent = new Intent(); myintent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA); startActivityForResult(myintent, MY_DATA_CHECK_CODE); } protected void onActivityResult(int requestcode,int resultcode,Intent data) { if(requestcode == MY_DATA_CHECK_CODE) { if(resultcode==TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) { // success so create the TTS engine mtts = new TextToSpeech(this,this); mtts.setLanguage(Locale.ENGLISH); } else { //install the Engine Intent install = new Intent(); install.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA); startActivity(install); } } } public void onDestroy(Bundle savedInstanceStatBundle) { mtts.shutdown(); } public void onPause() { super.onPause(); // if our app has no focus if(mtts!=null) mtts.stop(); } @Override public void onInit(int status) { if(status==TextToSpeech.SUCCESS) button.setEnabled(true); } } and the Receiver programme is: package com.example.TextSpeaker; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.speech.tts.TextToSpeech; import android.telephony.SmsMessage; // supports both gsm and cdma import android.widget.Toast; public class Receiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { Bundle bundle = intent.getExtras(); SmsMessage[] msgs = null; String str=""; if(bundle!=null) { // retrive the sms received Object[] pdus = (Object[])bundle.get("pdus"); msgs = new SmsMessage[pdus.length]; for(int i=0;i } } }

  This is my code @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.email_list_main); emailResults = new ArrayList<GetEmailFromDatabase>(); //int[] colors = {0,0xFFFF0000,0}; //getListView().setDivider(new GradientDrawable(Orientation.RIGHT_LEFT, colors)); //getListView().setDividerHeight(2); emailListFeedAdapter = new EmailListFeedAdapter(this, R.layout.email_listview_row, emailResults); setListAdapter(this.emailListFeedAdapter); getResults(); if(emailResults != null && emailResults.size() > -1){ emailListFeedAdapter.notifyDataSetChanged(); for(int i=0;i< emailResults.size();i++){ try { Here I getting email Sent date emailListFeedAdapter.add( emailResults.get(i)); datetime_text1 = emailResults.get(i).getDate(); formatter1 = new SimpleDateFormat(); formatter1 = DateFormat.getDateInstance((DateFormat.MEDIUM)); Calendar currentDate1 = Calendar.getInstance(); Item_Date1 = formatter1.parse(datetime_text1); current_Date1 = formatter1.format(currentDate1.getTime()); current_System_Date1 = formatter1.parse(current_Date1); currentDate1.add(Calendar.DATE, -1); yesterdaydate = formatter1.format(currentDate1.getTime()); yeaterday_Date = formatter1.parse(yesterdaydate); currentDate1.add(Calendar.DATE, -2); threeDaysback = formatter1.format(currentDate1.getTime()); Three_Days_Back = formatter1.parse(threeDaysback); Here I am comparing current date with list view item date, and here is my problem, dates are matching but it is not entering in if condition I tried in so many ways but nothing worked the code for separator is bellow. if(Item_Date.compareTo(current_System_Date)==0){ if(index1){ emailListFeedAdapter.addSeparatorItem("SEPARATOR"); //i--; index1=false; } } else if(yeaterday_Date.compareTo(Item_Date1)==0){ if(index2){ emailListFeedAdapter.addSeparatorItem("SEPARATOR"); //i--; index2 = false; } } else if(Item_Date1.compareTo(Three_Days_Back)==0){ if(index3){ emailListFeedAdapter.addSeparatorItem("SEPARATOR"); //i--; index3 = false; } } } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } } In EmailListFeedAdapter private TreeSet<Integer> mSeparatorsSet = new TreeSet<Integer>(); public void addSeparatorItem(final String item) { //itemss.add(emailResults.get(0)); // save separator position mSeparatorsSet.add(itemss.size() - 1); notifyDataSetChanged(); } @Override public int getItemViewType(int position) { return mSeparatorsSet.contains(position) ?

• Issue getting camera emulation to work with Tom G's HttpCamera

  - by user591524

  I am trying to use the android emulator to preview video from webcam. I have used the tom gibara sample code, minus the webbroadcaster (i am instead using VLC streaming via http). So, I have modified the SDK's "CameraPreview" app to use the HttpCamera, but the stream never appears. Debugging through doesn't give me any clues either. I wonder if anything obvious is clear to others? The preview app launches and remains black. Notes: 1) I have updated the original CameraPreview class as described here: http://www.inter-fuser.com/2009/09/live-camera-preview-in-android-emulator.html, but referencing httpCamera instead of socketcamera. 2) I updated Tom's original example to reference "Camera" type instead of deprecated "CameraDevice" type. 3) Below is my CameraPreview.java. 4) THANK YOU package com.example.android.apis.graphics; import android.app.Activity; import android.content.Context; import android.hardware.Camera; import android.os.Bundle; import android.view.SurfaceHolder; import android.view.SurfaceView; import android.view.Window; import java.io.IOException; import android.graphics.Canvas; // ---------------------------------------------------------------------- public class CameraPreview extends Activity { private Preview mPreview; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Hide the window title. requestWindowFeature(Window.FEATURE_NO_TITLE); // Create our Preview view and set it as the content of our activity. mPreview = new Preview(this); setContentView(mPreview); } } // ---------------------------------------------------------------------- class Preview extends SurfaceView implements SurfaceHolder.Callback { SurfaceHolder mHolder; //Camera mCamera; HttpCamera mCamera;//changed Preview(Context context) { super(context); // Install a SurfaceHolder.Callback so we get notified when the // underlying surface is created and destroyed. mHolder = getHolder(); mHolder.addCallback(this); //mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); mHolder.setType(SurfaceHolder.SURFACE_TYPE_NORMAL);//changed } public void surfaceCreated(SurfaceHolder holder) { // The Surface has been created, acquire the camera and tell it where // to draw. //mCamera = Camera.open(); this.StartCameraPreview(holder); } public void surfaceDestroyed(SurfaceHolder holder) { // Surface will be destroyed when we return, so stop the preview. // Because the CameraDevice object is not a shared resource, it's very // important to release it when the activity is paused. //mCamera.stopPreview();//changed mCamera = null; } public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { // Now that the size is known, set up the camera parameters and begin // the preview. //Camera.Parameters parameters = mCamera.getParameters(); //parameters.setPreviewSize(w, h); //mCamera.setParameters(parameters); //mCamera.startPreview(); this.StartCameraPreview(holder); } private void StartCameraPreview(SurfaceHolder sh) { mCamera = new HttpCamera("10.213.74.247:443", 640, 480, true);//changed try { //mCamera.setPreviewDisplay(holder); Canvas c = sh.lockCanvas(null); mCamera.capture(c); sh.unlockCanvasAndPost(c); } catch (Exception exception) { //mCamera.release(); mCamera = null; // TODO: add more exception handling logic here } } }

• Android: MediaPlayer gapless or seamless Video Playing

  - by John Wang

  I can play the videos fine back to back by implementing the OnCompletionListener to set the data source to a different file. No problems there. I call reset() and prepare() just fine. What I haven't been able to figure out, is how to get rid of the 1-2 second gap screen flicker between the data source change and the new video starting. The gap shows a black screen, and I haven't found any way to get around it. I've tried setting the background of the parent view to an image, but it manages to bypass that. Even if the SurfaceView is transparent (which it is by default.) I've also tried to have the multiple video files played at the same time, and switching mediaplayer's display when one ends and the other is supposed to start. The last thing I tried, was to have a second view in the background that I show temporarily while the video is "preparing" and removing it when the video is ready to start. That also wasn't very seamless. Is there any way to get rid of that gap. Running a video in a loop works wonderfully and does exactly what I want with the exception that it's looking through the same video instead of playing a different one that I pick. main.xml <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:background="@drawable/background" android:layout_height="fill_parent"> <SurfaceView android:id="@+id/surface" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center"> </SurfaceView> </FrameLayout> Player.java public class Player extends Activity implements OnCompletionListener, MediaPlayer.OnPreparedListener, SurfaceHolder.Callback { private MediaPlayer player; private SurfaceView surface; private SurfaceHolder holder; public void onCreate(Bundle b) { super.onCreate(b); setContentView(R.layout.main); surface = (SurfaceView)findViewById(R.id.surface); holder = surface.getHolder(); holder.addCallback(this); holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public void onCompletion(MediaPlayer arg0) { File clip = new File(Environment.getExternalStorageDirectory(),"file2.mp4"); playVideo(clip.getAbsolutePath()); } public void onPrepared(MediaPlayer mediaplayer) { holder.setFixedSize(player.getVideoWidth(), player.getVideoHeight()); player.start(); } private void playVideo(String url) { try { File clip = new File(Environment.getExternalStorageDirectory(),"file1.mp4"); if (player == null) { player = new MediaPlayer(); player.setScreenOnWhilePlaying(true); } else { player.stop(); player.reset(); } player.setDataSource(url); player.setDisplay(holder); player.setOnPreparedListener(this); player.prepare(); player.setOnCompletionListener(this); } catch (Throwable t) { Log.e("ERROR", "Exception Error", t); } }

• JSON Paring - How to show second Level ListView

  - by Sophie

  I am parsing JSON data into ListView, and successfully parsed first level of JSON in MainActivity.java, where i am showing list of Main Locations, like: Inner Locations Outer Locations Now i want whenever i do tap on Inner Locations then in SecondActivity it should show Delhi and NCR in a List, same goes for Outer Locations as well, in this case whenever user do tap need to show USA JSON look like: { "all": [ { "title": "Inner Locations", "maps": [ { "title": "Delhi", "markers": [ { "name": "Connaught Place", "latitude": 28.632777800000000000, "longitude": 77.219722199999980000 }, { "name": "Lajpat Nagar", "latitude": 28.565617900000000000, "longitude": 77.243389100000060000 } ] }, { "title": "NCR", "markers": [ { "name": "Gurgaon", "latitude": 28.440658300000000000, "longitude": 76.987347699999990000 }, { "name": "Noida", "latitude": 28.570000000000000000, "longitude": 77.319999999999940000 } ] } ] }, { "title": "Outer Locations", "maps": [ { "title": "United States", "markers": [ { "name": "Virgin Islands", "latitude": 18.335765000000000000, "longitude": -64.896335000000020000 }, { "name": "Vegas", "latitude": 36.114646000000000000, "longitude": -115.172816000000010000 } ] } ] } ] } Note: But whenever i do tap on any of the ListItem in first activity, not getting any list in SecondActivity, why ?

• Update UI from an event with a thread

  - by tyrone-tudehope

  Im working on a small application to try out an idea that I have. The idea is to periodically update the UI when event of some sort occurs. In the demo I've created, I'm updating a ProgressDialog every 2 seconds for 15 turns. The problem I am having, which I don't quite understand is that when an event is handled, I send a message to the handler which is supposed to update the message in the ProgressDialog. When this happens however, I get an exception which states that I can't update the UI from that thread. The following code appears in my Activity: ProgressDialog diag; String diagMessage = "Started loading..."; final static int MESSAGE_DATA_RECEIVED = 0; final static int MESSAGE_RECEIVE_COMPLETED = 1; final Handler handler = new Handler(){ @Override public void handleMessage(Message msg){ diag.setMessage(diagMessage); switch(msg.what){ case MESSAGE_DATA_RECEIVED: break; case MESSAGE_RECEIVE_COMPLETED: dismissDialog(); killDialog(); break; } } }; Boolean isRunning = false; /** * Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setupDialog(); if(isRunning){ showDialog(); } setContentView(R.layout.main); } void setupDialog(){ if(diag == null){ diag = new ProgressDialog(ThreadLoading.this); diag.setMessage(diagMessage); } } void showDialog(){ isRunning = true; if(diag != null && !diag.isShowing()){ diag.show(); } } void dismissDialog(){ if(diag != null && diag.isShowing()){ diag.dismiss(); } } void killDialog(){ isRunning = false; } public void onStart(){ super.onStart(); showDialog(); Thread background = new Thread(new Runnable(){ public void run(){ try{ final ThreadRunner tr = new ThreadRunner(); tr.setOnDataReceivedListener(new ThreadRunner.OnDataReceivedListener(){ public void onDataReceived(String message){ diagMessage = message; handler.handleMessage(handler.obtainMessage(MESSAGE_DATA_RECEIVED)); } }); tr.setOnDataDownloadCompletedEventListener(new ThreadRunner.OnDataDownloadCompletedListener(){ public void onDataDownloadCompleted(String message){ diagMessage = message; handler.handleMessage(handler.obtainMessage(MESSAGE_RECEIVE_COMPLETED)); } }); tr.runProcess(); } catch(Throwable t){ throw new RuntimeException(t); } } }); background.start(); } @Override public void onPause(){ super.onPause(); dismissDialog(); } For curiosity sake, here's the code for the ThreadRunner class: public interface OnDataReceivedListener { public void onDataReceived(String message); } public interface OnDataDownloadCompletedListener { public void onDataDownloadCompleted(String message); } private OnDataReceivedListener onDataReceivedEventListener; private OnDataDownloadCompletedListener onDataDownloadCompletedEventListener; int maxLoop = 15; int loopCount = 0; int sleepTime = 2000; public void setOnDataReceivedListener(OnDataReceivedListener onDataReceivedListener){ this.onDataReceivedEventListener = onDataReceivedListener; } public void setOnDataDownloadCompletedEventListener(OnDataDownloadCompletedListener onDataDownloadCompletedListener){ this.onDataDownloadCompletedEventListener = onDataDownloadCompletedListener; } public void runProcess(){ for(loopCount = 0; loopCount < maxLoop; loopCount++){ try{ Thread.sleep(sleepTime); onDataReceivedEventListener.onDataReceived(Integer.toString(loopCount)); } catch(Throwable t){ throw new RuntimeException(t); } } onDataDownloadCompletedEventListener.onDataDownloadCompleted("Download is completed"); } Am I missing something? The logic makes sense to me and it looks like everything should work, I'm using a handler to update the UI like it is recommended. Any help will be appreciated. Thanks, Tyrone P.S. I'm developing for Android 1.5

This is my MainActivity: ListAdapter adapter; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); search = (EditText) findViewById(R.id.search); lista = (ListView) findViewById(android.R.id.list); sqlite = new Sqlite(MainActivity.this); //When apps start, listView is populated with data adapter = new SimpleAdapter(this, sqlite.getAllData(), R.layout.lv_layout, new String[]{"ime","naziv","kolicina","adresa"}, new int[]R.id.kupac,R.id.proizvod,R.id.kolicina,R.id.adresa}); setListAdapter(adapter); search.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before,int count) { // TODO Auto-generated method stub String tekst = s.toString(); ArrayList<HashMap<String, String>> rez = Sqlite.getFilterData(tekst); adapter = new SimpleAdapter(MainActivity.this, rez,R.layout.lv_layout, new String[]{"ime","naziv","kolicina","adresa"}, new int[]{R.id.kupac,R.id.proizvod,R.id.kolicina,R.id.adresa}); lista.setAdapter(adapter); } } The problem is when the method onTextChanged is called. I get all the data but the data just append to my ListView. How to fix it? And this is my Sqlite class where is needed method: ArrayList<HashMap<String,String>> results_criteria = new ArrayList<HashMap<String,String>>(); public ArrayList<HashMap<String, String>> getFilterData(String criteria) { String ime_kupca = ""; String product = ""; String adress = ""; String kolicina = ""; SQLiteDatabase myDb = this.getReadableDatabase(); Cursor cursor = myDb.rawQuery("SELECT " + DB_COLUMN_IME + "," + DB_COLUMN_NAZIV + "," + DB_COLUMN_KOLICINA + "," + DB_COLUMN_ADRESA + " FROM " + DB_TABLE1_NAME + "," + DB_TABLE2_NAME + " WHERE kupac.ID = proizvod.ID AND " + DB_COLUMN_IME + " LIKE '%" + criteria + "%'", null); if(cursor != null){ if(cursor.moveToFirst()){ do{ HashMap<String,String>map = new HashMap<String,String>(); ime_kupca = cursor.getString(cursor.getColumnIndex(DB_COLUMN_IME)); product = cursor.getString(cursor.getColumnIndex(DB_COLUMN_NAZIV)); kolicina = cursor.getString(cursor.getColumnIndex(DB_COLUMN_KOLICINA)); adress = cursor.getString(cursor.getColumnIndex(DB_COLUMN_ADRESA)); map.put("ime", ime_kupca); map.put("naziv", product); map.put("kolicina", kolicina); map.put("adresa", adress); results_criteria.add(map); }while(cursor.moveToNext()); //cursor.close(); } cursor.close(); } Log.i("Rez", "" + results_criteria); return results_criteria;

• How to implement wait(); to wait for a notifyAll(); from enter button?

  - by Dakota Miller

  Sorry for the confusion I posted the Worng Logcat info. I updated the question. I want to click Start to start a thread then when enter is clicked i want the thad to continue and get the message and handle the message in the thread then output it to the main thread and update the text view. How would i start a thread to wait for enter to be pressed and get the bundle for the Handler? Here is my Code: public class MainActivity extends Activity implements OnClickListener { Handler mHandler; Button enter; Button start; TextView display; String dateString; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); enter = (Button) findViewById(R.id.enter); start = (Button) findViewById(R.id.start); display = (TextView) findViewById(R.id.Display); enter.setOnClickListener(this); start.setOnClickListener(this); mHandler = new Handler() { <=============================This is Line 31 public void handleMessage(Message msg) { // TODO Auto-generated method stub super.handleMessage(msg); Bundle bundle = msg.getData(); String string = bundle.getString("outKey"); display.setText(string); } }; } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } @Override public void onClick(View v) { // TODO Auto-generated method stub switch (v.getId()) { case R.id.enter: Message msgin = Message.obtain(); Bundle bundlein = new Bundle(); String in = "It Works!"; bundlein.putString("inKey", in); msgin.setData(bundlein); notifyAll(); break; case R.id.start: new myThread().hello.start(); break; } } public class myThread extends Thread { Thread hello = new Thread() { @Override public void run() { // TODO Auto-generated method stub super.run(); Looper.prepare(); try { wait(); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } Handler Mhandler = new Handler() { @Override public void handleMessage(Message msg) { // TODO Auto-generated method stub super.handleMessage(msg); Bundle bundle = msg.getData(); dateString = bundle.getString("inKey"); } }; Looper.loop(); Message msg = Message.obtain(); Bundle bundle = new Bundle(); bundle.putString("outKey", dateString); msg.setData(bundle); mHandler.sendMessage(msg); } }; } } Here is the logcat info: 06-27 00:00:24.832: E/AndroidRuntime(18513): FATAL EXCEPTION: Thread-1210 06-27 00:00:24.832: E/AndroidRuntime(18513): java.lang.IllegalMonitorStateException: object not locked by thread before wait() 06-27 00:00:24.832: E/AndroidRuntime(18513): at java.lang.Object.wait(Native Method) 06-27 00:00:24.832: E/AndroidRuntime(18513): at java.lang.Object.wait(Object.java:364) 06-27 00:00:24.832: E/AndroidRuntime(18513): at com .example.learninghandlers.MainActivity$myThread$1.run(MainActivity.java:77)

• NullPointerException using EndlessAdapter with SimpleAdapter

  - by android_dev

  Hello, I am using EndlessAdapter from commonsguy with a SimpleAdapter. I can load data when I make a scroll down without problems, but I have a NullPointerException when I make a scroll up. The problem is in the method @Override public View getView(int position, View convertView,ViewGroup parent) { return wrapped.getView(position, convertView, parent); } from the class AdapterWrapper. The call to wrapped.getView(position, convertView,parent) raises the exception and I don´t know why. This is my implementation of EndlessAdapter: //Inner class in SearchTextActivity class DemoAdapter extends EndlessAdapter { private RotateAnimation rotate = null; DemoAdapter(ArrayList<HashMap<String, String>> result) { super(new SimpleAdapter(SearchTracksActivity.this, result, R.layout.textlist_item, PROJECTION_COLUMNS, VIEW_MAPPINGS)); rotate = new RotateAnimation( 0f, 360f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); rotate.setDuration(600); rotate.setRepeatMode(Animation.RESTART); rotate.setRepeatCount(Animation.INFINITE); } @Override protected View getPendingView(ViewGroup parent) { View row=getLayoutInflater().inflate(R.layout.textlist_item, null); View child=row.findViewById(R.id.title); child.setVisibility(View.GONE); child=row.findViewById(R.id.username); child.setVisibility(View.GONE); child=row.findViewById(R.id.throbber); child.setVisibility(View.VISIBLE); child.startAnimation(rotate); return row; } @Override @SuppressWarnings("unchecked") protected void rebindPendingView(int position, View row) { HashMap<String, String> res = (HashMap<String, String>)getWrappedAdapter().getItem(position); View child=row.findViewById(R.id.title); ((TextView)child).setText(res.get("title")); child.setVisibility(View.VISIBLE); child=row.findViewById(R.id.username); ((TextView)child).setText(res.get("username")); child.setVisibility(View.VISIBLE); ImageView throbber=(ImageView)row.findViewById(R.id.throbber); throbber.setVisibility(View.GONE); throbber.clearAnimation(); } boolean mFinal = true; @Override protected boolean cacheInBackground() { EditText searchText = (EditText)findViewById(R.id.searchText); String textToSearch = searchText.getText().toString(); Util.getSc().searchText(textToSearch , offset, limit, new ResultListener<ArrayList<Text>>() { @Override public void onError(Exception e) { e.toString(); mFinal = false; } @Override public void onSuccess(ArrayList<Text> result) { if(result.size() == 0){ mFinal = false; }else{ texts.addAll(result); offset++; } } }); return mFinal; } @Override protected void appendCachedData() { for(Text text : texts){ result.add(text.getMapValues()); } texts.clear(); } } And I use it this way: public class SearchTextActivity extends AbstractListActivity { private static final String[] PROJECTION_COLUMNS = new String[] { TextStore.Text.TITLE, TextStore.Text.USER_NAME}; private static final int[] VIEW_MAPPINGS = new int[] { R.id.Text_title, R.id.Text_username}; ArrayList<HashMap<String, String>> result; static ArrayList<Text> texts; static int offset = 0; static int limit = 1; @Override void onAbstractCreate(Bundle savedInstance) { setContentView(R.layout.search_tracks); setupViews(); } private void setupViews() { ImageButton searchButton = (ImageButton)findViewById(R.id.searchButton); updateView(); } SimpleAdapter adapter; void updateView(){ if(result == null) { result = new ArrayList<HashMap<String, String>>(); } if(tracks == null) { texts = new ArrayList<Text>(); } } public void sendQuery(View v){ offset = 0; texts.clear(); result.clear(); setListAdapter(new DemoAdapter(result)); } } Does anybody knows what could be the problem? Thank you in advance

• Write to file depending on minSdkVersion - android

  - by Simon Rosenqvist

  Hi, I have written a filewriter for my android application. It is to function on a Galaxy Tab, so my minSdkVersion has to be at least 4, so it will fill the screen. I originally started out with SdkVersion = 2 and at that point my filewriter worked perfectly. Changing the SdkVersion to 4 introduced the problem. My filewriter doesn't work anymore! The application runs fine, but a file doesn't get created. My .java file looks like this: public class HelloAndroid extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); tv.setText("Hello, Android"); setContentView(R.layout.main); //definerer en knap kaldet button1 og sætter en listener på denne. Button button1 = (Button)findViewById(R.id.btnClickMe); button1.setOnClickListener(btnListener); //definerer en knap kaldet button2 og sætter en listener på denne. Button button2 = (Button)findViewById(R.id.btnClickMe2); button2.setOnClickListener(btnListener2); } //en variabel af typen 'long' deklæres og kaldes tid1. public long time1; private OnClickListener btnListener = new OnClickListener() { public void onClick(View v) { //Når der klikkes på button1 gemmes et tal i variablen tid1. time1 = System.currentTimeMillis(); } }; //en variabel af typen 'long' deklæres og kaldes tid2. public long time2; // en variabel af typen 'string' deklæres og kaldes tid: public String string1 = "time:"; private OnClickListener btnListener2 = new OnClickListener() { public void onClick(View v) { //Når der klikkes på button2 gemmes et tal i variablen tid2. time2 = System.currentTimeMillis(); // Herefter oprettes en fil kaldet "file.txt". try{ File file = new File(Environment.getExternalStorageDirectory(), "file.txt"); file.createNewFile(); BufferedWriter writer = new BufferedWriter(new FileWriter(file,true)); //string1 og tid2-tid1 skrives til filen. tid2-tid1 giver den tid der går fra der er trykket på den ene knap til den anden i millisekunder. writer.write(string1 + "\t" + (time2-time1)); writer.newLine(); writer.flush(); writer.close(); } catch (IOException e) { e.printStackTrace(); } } }; } And my manifest.xml looks like this: <?xml version="1.0" encoding="utf-8"?> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".HelloAndroid" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> Why does my filewriter not work with minSdkVersion 2? Do i have to make a new filewriter? or what to do? Sorry for the messy code, i'm quite new to programming :)

• android program crashing (new to platform)

  So it is my first real Android program (!hello world), but i do have java experience.The program compiles fine, but on running it crashes as soon as it opens (tried debugging, but it crashes before it hits my breakpoint). Was looking for any advice from anyone who is more experienced with android. package org.me.tipcalculator; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; import android.view.View; import android.widget.Button; import android.widget.EditText; import java.text.NumberFormat; import android.util.Log; public class TipCalculator extends Activity { public static final String tag = "TipCalculator"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); final EditText mealpricefield = (EditText) findViewById(R.id.mealprice); final TextView answerfield = (TextView) findViewById(R.id.answer); final Button button = (Button) findViewById(R.id.calculate); button.setOnClickListener(new Button.OnClickListener() { public void onClick(View v) { try { Log.i(tag, "onClick invoked."); String mealprice = mealpricefield.getText().toString(); Log.i(tag, "mealprice is [" + mealprice + "]"); String answer = ""; if (mealprice.indexOf("$") == -1) { mealprice = "$" + mealprice; } float fmp = 0.0F; NumberFormat nf = java.text.NumberFormat.getCurrencyInstance(); fmp = nf.parse(mealprice).floatValue(); fmp *= 1.2; Log.i(tag, "Total Meal Price (unformatted) is [" + fmp + "]"); answer = "Full Price, including 20% Tip: " + nf.format(fmp); answerfield.setText(answer); Log.i(tag, "onClick Complete"); } catch(java.text.ParseException pe){ Log.i (tag ,"Parse exception caught"); answerfield.setText("Failed to parse amount?"); } catch(Exception e){ Log.e (tag ,"Failed to Calculate Tip:" + e.getMessage()); e.printStackTrace(); answerfield.setText(e.getMessage()); } } } ); } Just in case it helps heres the xml <?xml version="1.0" encoding="UTF-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Android Tip Calculator"/> <EditText android:id="@+id/mealprice" android:layout_width="fill_parent" android:layout_height="wrap_content" android:autoText="true"/> <Button android:id="@+id/calculate" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Calculate Tip"/> <TextView android:id= "@+id/answer" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text=""/> </LinearLayout>

• ViewPager and Fragment Pager adapter implementation

  So I am trying to implement sliding views/fragments using viewpager and fragment pager adapter. convert_home is my main xml file that has android.support.v4.view.PagerTitleStrip and temperature.xml and velocity.xml are my two other views. I have no clue where I am going wrong. package app.converto; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentActivity; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentPagerAdapter; import android.support.v4.view.ViewPager; import android.view.LayoutInflater; import android.view.Menu; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; public class ConverTo extends FragmentActivity { SectionsPagerAdapter mSectionsPagerAdapter; ViewPager mViewPager; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager()); mViewPager.setAdapter(mSectionsPagerAdapter); setContentView(R.layout.converto_home); mViewPager = (ViewPager) findViewById(R.id.pager); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.converto_home, menu); return true; } public class SectionsPagerAdapter extends FragmentPagerAdapter { public SectionsPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int i) { switch(i){ case 0: Fragment1 fragment = new Fragment1(); return fragment; case 1: Fragment2 fragment2 = new Fragment2(); return fragment2; } defaultFragment fragment3 = new defaultFragment(); return fragment3; } @Override public int getCount() { return 2; } // // @Override // public CharSequence getPageTitle(int position) { // switch (position) { // case 0: return getString(R.string.velocity); // case 1: return getString(R.string.temperature); // case 2: return getString(R.string.distance); // } // return null; // } } public static class Fragment1 extends Fragment{ public Fragment1(){ } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { //return inflater.inflate(R.layout.temperature, container, false); View view = inflater.inflate(R.layout.temperature, container, false); TextView textView = (TextView) view.findViewById(R.id.sample); textView.setText(getArguments().getString("title")); return view; } } public static class Fragment2 extends Fragment{ public Fragment2(){ } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { //return inflater.inflate(R.layout.velocity, container, false); View view = inflater.inflate(R.layout.temperature, container, false); TextView textView = (TextView) view.findViewById(R.id.sample); textView.setText(getArguments().getString("title")); return view; } } public static class defaultFragment extends Fragment{ public defaultFragment(){ }//end constructor @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // return inflater.inflate(R.layout.temperature, container, false); View view = inflater.inflate(R.layout.temperature, container, false); TextView textView = (TextView) view.findViewById(R.id.sample); textView.setText(getArguments().getString("title")); return view; }//end oncreate }//end default fragment }
