  • WebView inside Tab hiding the tabWidgets

    - by brockoli
    I'm having trouble with a WebView always filling the full screen and thus covering my tabs. Here is my code for the tabhost.. public class tabNZBMobile extends TabActivity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); Resources res = getResources(); // Resource object to get Drawables TabHost tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Reusable TabSpec for each tab Intent intent; // Reusable Intent for each tab // Create an Intent to launch an Activity for the tab (to be reused) intent = new Intent().setClass(this, NewzbinMobile.class); // Initialize a TabSpec for each tab and add it to the TabHost spec = tabHost.newTabSpec("search").setIndicator("Search", res.getDrawable(R.drawable.ic_tab_search)) .setContent(intent); tabHost.addTab(spec); // Do the same for the other tabs intent = new Intent().setClass(this, sabnzbWeb.class); spec = tabHost.newTabSpec("sabnzbweb").setIndicator("SabNZBd", res.getDrawable(R.drawable.ic_tab_sabnzbweb)) .setContent(intent); tabHost.addTab(spec); tabHost.setCurrentTabByTag("search"); }} My first tab (NewzbinMobile.class) displays correctly, it's just a relativelayout. But my second tab is an activity showing a webview and it is showing, but using the whole screen, covering my tabs. Here is the code for my second tab. public class sabnzbWeb extends Activity { WebView mWebView; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); String sabNZBurl = new String("http://test.server.org:8080/m"); mWebView = new WebView(this); mWebView.getSettings().setJavaScriptEnabled(true); setContentView(mWebView); mWebView.loadUrl(sabNZBurl); }}

  • Android: Can not send http post

    - by jpartogi
    Hi all, I've been banging my head trying to figure out how to send a post method in Android. This is how my code look like: public class HomeActivity extends Activity implements OnClickListener { private TextView textView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); textView = (TextView) findViewById(R.id.text); Button button = (Button)findViewById(R.id.button); button.setOnClickListener(this); } @Override public void onClick(View view) { HttpPost httpMethod = new HttpPost("http://www.example.com/"); httpMethod.addHeader("Accept", "text/html"); httpMethod.addHeader("Content-Type", "application/xml"); AndroidHttpClient client = AndroidHttpClient.newInstance("Android"); String result = null; try { HttpResponse response = client.execute(httpMethod); textView.setText(response.toString()); HttpEntity entity = response.getEntity(); Log.i(HomeActivity.class.toString(), result); textView.setText("Invoked webservice"); } catch (IOException e) { e.printStackTrace(); Log.e(HomeActivity.class.toString(), e.getMessage()); textView.setText("Something wrong:" + e.getMessage()); } } } What am I doing wrong here? Is there anything that I may need to configure from the Android emulator to get this working? Thank you for your help.

  • Android beginner: understanding MotionEvent actions

    - by Dave
    I am having trouble getting my activity to return a MotionEvent.ACTION_UP. Probably a beginner's error. In LogCat, I'm only seeing the ACTION_MOVE event (which is an int value of 3). I also see the X/Y coordinates. No ACTION_DOWN and no ACTION_UP. I looked everywhere for a solution. I found one question on a forum that seems to be the same as my issue, but no solution is proposed: http://groups.google.com/group/android-developers/browse_thread/thread/9a9c23e40f02c134/bf12b89561f204ad?lnk=gst&q=ACTION_UP#bf12b89561f204ad Here's my code: import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.view.MotionEvent; import android.webkit.WebView; public class Brand extends Activity { public WebView webview; public float currentXPosition; public float currentYPosition; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); webview = new WebView(this); setContentView(webview); webview.loadUrl("file:///android_asset/Brand.html"); } @Override public boolean onTouchEvent(MotionEvent me) { int action = me.getAction(); currentXPosition = me.getX(); currentYPosition = me.getY(); Log.v("MotionEvent", "Action = " + action); Log.v("MotionEvent", "X = " + currentXPosition + "Y = " + currentYPosition); if (action == MotionEvent.ACTION_MOVE) { // do something } if (action == MotionEvent.ACTION_UP) { // do something } return true; } }

    - by Alex Volovoy
    Hi all i've ran into another problems with VideoView. Then video is playing, and i put device asleep, using hard button, onPause is called. But it followed by 03-17 11:26:33.779: WARN/ActivityManager(884): Activity pause timeout for HistoryRecord{4359f620 com.package/com.package.VideoViewActivity} And then i have onStart/onResume again and Video starts playing.

  • How do I get my ActivityUnitTestCases to sync with the MessageQueue thread and call my Handler?

    - by Ricardo Gladwell
    I'm writing unit tests for a ListActivity in Android that uses a handler to update a ListAdapter. While my activity works in the Android emulator, running the same code in a unit test doesn't update my adapter: calls to sendEmptyMessage do not call handleMessage in my activity's Handler. How do I get my ActivityUnitTestCase to sync with the MessageQueue thread and call my Handler? The code for the Activity is somewhat like this: public class SampleActivity extends ListActivity implements SampleListener { List samples = new ArrayList(); public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.sample_list); listView.setEmptyView(findViewById(R.id.empty)); } private final Handler handler = new Handler() { @Override public void handleMessage(Message msg) { // unit test never reaches here sharesAdapter = new SampleAdapter(SampleActivity.this, samples); setListAdapter(sharesAdapter); } }; public void handleSampleUpdate(SampleEvent event) { samples.add(event.getSample()); handler.sendEmptyMessage(0); } } The code for my unit test is somewhat like this: public class SampleActivityTest extends ActivityUnitTestCase<SampleActivity> { public SampleActivityTest() { super(SampleActivity.class); } @MediumTest public void test() throws Exception { final SampleActivity activity = startActivity(new Intent(Intent.ACTION_MAIN), null, null); final ListView listView = (ListView) activity.findViewById(android.R.id.list); activity.handleSampleUpdate(new SampleEvent(this)); // unit test assert fails on this line: assertTrue(listView.getCount() == 1); } }

  • Android java.lang.VerifyError for private method with annotated argument.

    - by alex2k8
    I have a very simple project that compiles, but can't be started on Emulator. The problem is with this method: private void bar(@Some String a) {} // java.lang.VerifyError The issue can be avoided if annotation removed private void bar(String a) {} // OK or the method visibility changed: void bar(@Some String a) {} // OK public void bar(@Some String a) {} // OK protected void bar(@Some String a) {} // OK Any idea what is wrong with original method?

  • Pressing back button in ActivityGroup causes it to pause, and then continue shutting down the next t

    - by synic
    Pressing the back button causes onPause to be called, and the app stays paused until it is re-launched by clicking on the icon, at which point, onDestroy gets called, and the main activity continues to shut down. Simple class to demonstrate. Note, as far as I can tell, this only happens on the Nexus One. I can't reproduce it in the emulator or on my Droid. package com.vimtips.testshutdown; import android.app.ActivityGroup; import android.os.Bundle; import android.util.Log; import android.view.KeyEvent; public class MainActivity extends ActivityGroup { private static final String TAG = "MainActivity"; private int counter = 3; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } public boolean onKeyDown(int keyCode, KeyEvent event) { if(keyCode == KeyEvent.KEYCODE_BACK) { if(counter-- > 0) return true; } return super.onKeyDown(keyCode, event); } @Override public void onPause() { super.onPause(); Log.d(TAG, "onPause called"); } @Override public void onDestroy() { super.onDestroy(); if(isFinishing()) { Log.d(TAG, "Shutting down"); } } } And here's the log: I/ActivityManager( 132): Starting activity: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10100000 cmp=com.vimtips.testshutdown/.MainActivity } I/ActivityManager( 132): Displayed activity com.vimtips.testshutdown/.MainActivity: 305 ms (total 305 ms) D/MainActivity( 1393): onPause called I/ActivityManager( 132): Displayed activity com.vimtips.testshutdown/.MainActivity: 302 ms (total 302 ms) D/MainActivity( 1393): Shutting down This doesn't appear to happen on a normal Activity, just an Activity group, though looking at Android's sourcecode, I can't figure out why. It's causing some serious problems with my app. Anyone know why this would happen?

  • Application lifecycle and onCreate method in the the android sdk

    - by Leif Andersen
    I slapped together a simple test application that has a button, and makes a noise when the user clicks on it. Here are it's method: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button b = (Button)findViewById(R.id.easy); b.setOnClickListener(this); } public void onClick(View v) { MediaPlayer mp = MediaPlayer.create(this, R.raw.easy); mp.start(); while(true) { if (!mp.isPlaying()) { mp.release(); break; } } } My question is, why is onCreate acting like it's in a while loop? I can click on the button whenever, and it makes the sound. I might think it was just a property of listeners, but the Button object wasn't a member variable. I thought that Android would just go through onCreate onse, and proceed onto the next lifecycle method. Also, I know that my current way of seeing if the sound is playing is crap...I'll get to that later. :) Thank you.

  • Is there a better way to refresh WebView?

    - by cdg
    Hi all. Ok. I have looked EVERYWHERE and my little brain just can't understand a better way to refresh an activity. Any suggestions that I can understand would be great. :) Here is the java code: package com.dge.dges; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.webkit.WebView; import android.widget.Button; public class dgeActivity extends Activity { WebView mWebView; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mWebView = (WebView) findViewById(R.id.webview); mWebView.getSettings(); mWebView.loadUrl("http://www.websitehere.php"); Button newButton = (Button)findViewById(R.id.new_button); newButton.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Intent intent = new Intent(dgeActivity.this, dgeActivity.class); startActivity(intent); } }); } } And here is the main.xml <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/RelativeLayout" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#000000" > <WebView android:id="@+id/webview" android:layout_width="fill_parent" android:layout_height="wrap_content" android:scrollbars="none" /> <Button android:id="@+id/new_button" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" android:text="Refresh" /> </RelativeLayout> I don't like the idea of just re-stacking activity after activity. There has to be an easier way to refresh the webview. Please help. :)

  • How can I set drawable to a ListView in android

    - by sxingfeng
    I am writing a app for android 1.5. I want to use a complex listview to display my data. I want to show a ImageView of a drawable object in my List item. I learned from a demo: ------> listData.put("Img", listData.put("Img", R.drawable.XXX)); listData.put("Time", "100"); listItems.add(listData); It can display correctly, however, I want to change Img at runtime, The image maybe generated at run-time, so I change the code as follow, but it falls. Can anyone help me ? many thanks! protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.item_list); itemListView = (ListView) findViewById(R.id.listview); ArrayList<HashMap<String, Object>> listItems = new ArrayList<HashMap<String, Object>>(); for(int i = 0;i <XXX.size(); ++i) { HashMap<String, Object> listData = new HashMap<String, Object>(); ---------> 1) listData.put("Img", new Drawable(XXX)); 2) listData.put("Time", "100"); 3) listItems.add(listData); } SimpleAdapter listItemAdapter = new SimpleAdapter(this, listItems, R.layout.listitem, new String[] { "Img", "Time"}, new int[] { R.id.listitem_img, R.id.listitem_time }); itemListView.setAdapter(listItemAdapter); listitem.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout android:layout_width="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:paddingBottom="4dip" android:paddingLeft="12dip" android:paddingRight="12dip"> <ImageView android:paddingTop="12dip" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/listitem_img" /> <TextView android:layout_height="wrap_content" android:textSize="20dip" android:layout_width="wrap_content" android:id="@+id/listitem_time" /> </LinearLayout>

  • How to open AsyncTask from a Thread

    - by Abhishek
    In my application I have created a SplashScreen that will b shown for 5 Seconds and after that it executes an if else case depending upon the values stored in the Preference file. If Preference file contains values then the AsyncTask code will run else the Login form will load. When i try to run my application. The thread is going to the Login form with the help of intent but when it comes to AsyncTask my application shows a force close error message. This is my SplashScreen code: public class SplashScreen extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.splashscreen); Thread timer = new Thread() { public void run() { try { sleep(5000); } catch(InterruptedException e) { e.printStackTrace(); } finally { if(GoGolfPref.getEmail(SplashScreen.this)!=null && GoGolfPref.getPass(SplashScreen.this)!=null) { new LoadingScreen(SplashScreen.this, SplashScreen.this).execute("login_page", Login.url+GoGolfPref.getEmail(SplashScreen.this)+"/"+GoGolfPref.getPass(SplashScreen.this)); } else { Intent in = new Intent(SplashScreen.this, Login.class); startActivity(in); finish(); } } } }; timer.start(); } } This is the error I am getting: 08-29 07:25:58.040: E/AndroidRuntime(2365): FATAL EXCEPTION: Thread-10 08-29 07:25:58.040: E/AndroidRuntime(2365): java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.os.Handler.<init>(Handler.java:121) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.Dialog.<init>(Dialog.java:101) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.AlertDialog.<init>(AlertDialog.java:63) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.ProgressDialog.<init>(ProgressDialog.java:80) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.ProgressDialog.<init>(ProgressDialog.java:76) 08-29 07:25:58.040: E/AndroidRuntime(2365): at com.pnf.gogolf.LoadingScreen.<init>(LoadingScreen.java:130) 08-29 07:25:58.040: E/AndroidRuntime(2365): at com.pnf.gogolf.SplashScreen$1.run(SplashScreen.java:32) How to get this working?

  • Theme change doesn't work on <4.0 as it should

    - by user1717276
    I have some difficulties with setting up a "theme switcher" programmatically. I would like to switch themes from app (between White (Theme.Light.NoTitleBar) and Dark (Theme.Black.NoTitleBar)) and what I do is: I set a SharedPreference: final String PREFS_NAME = "MyPrefsFile"; final SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0); final SharedPreferences.Editor editor = settings.edit(); and than I have a two buttons to switch themes (second one is almost identical) Button ThemeWhite = (Button) findViewById(R.id.ThemeWhite); ThemeWhite.setOnClickListener(new OnClickListener() { public void onClick(View v) { editor.putBoolean("Theme", false); editor.commit(); System.exit(2); } }); and in begging of each activity I check SharedPreference boolean theme = settings.getBoolean("Theme", false); if(theme){ this.setTheme(R.style.Theme_NoBarBlack); } else{ this.setTheme(R.style.Theme_NoBar); } setContentView(R.layout.aplikacja); I define themes in file styles.xml in folder values: <resources> <style name="Theme.NoBar" parent="@android:style/Theme.Light.NoTitleBar" /> <style name="Theme.NoBarBlack" parent="@android:style/Theme.NoActionBar" /> in values-v11: <resources> <style name="Theme.NoBar" parent="@android:style/Theme.Holo.Light.NoActionBar" /> <style name="Theme.NoBarBlack" parent="@android:style/Theme.Holo.NoActionBar" /> in values-v14: <resources> <style name="Theme.NoBar" parent="@android:style/Theme.DeviceDefault.Light.NoActionBar" /> <style name="Theme.NoBarBlack" parent="@android:style/Theme.DeviceDefault.NoActionBar" /> manifest file: <application android:theme="@style/Theme.NoBar" > Everything is working excellent on android 4.0 but when I use 2.2 it doesn't change theme - just font is getting white as it should be but there is no dark background. I tried checking if it at least works and changed Theme.NoBarBlack in values (for android <3.0) and its value the same as Theme.NoBar and then when I pressed button font wasn't changed -as it should do.

  • xml vs java LinearLayout fills

    the xml version below properly handles height and width and the java doesn't what is the java missing? xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="fill_parent" android:layout_width="fill_parent" android:orientation="horizontal"> <include android:id="@+id/cell1" layout="@layout/grid_text_view" /> <include android:id="@+id/cell2" layout="@layout/grid_text_view" /> </LinearLayout> java LinearLayout ll = new LinearLayout(this); ll.setOrientation(LinearLayout.HORIZONTAL); ll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); ll.addView((TextView)this.getLayoutInflater().inflate(R.layout.grid_text_view, null)); ll.addView((TextView)this.getLayoutInflater().inflate(R.layout.grid_text_view, null)); setContentView(ll); grid_text_view <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="fill_parent" android:layout_width="0dip" android:text="1" android:textSize="20sp" android:gravity="center" android:layout_weight="1" /> I've tried a ll.invalidate() and it didn't work either? :( screenshots at http://www.flickr.com/photos/48409507@N06/sets/72157623618407586/

  • Can't seem to load a webview from xml, why?

    - by Bilthon
    Well, I'm trying to follow the tutorial from http://rapidandroid.org/wiki/Graphing. But I found a problem just in the first part of it. I'll describe the problem here, I just cannot understand how this could be wrong, it's pretty simple stuff. What am I doing wrong here? First I created a xml file called statistics.xml, in it among other things I put this code: <WebView android:id="@+id/webview" android:layout_height="fill_parent" android:layout_width="fill_parent"/> Now in the activity that is supposed to display this webview I'm doing this: public class DisplayStatistics extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); WebView wv = (WebView) findViewById(R.id.webview); The problem arises here, as I seem to be getting null for wv whenever I test for it. Which means of course that findViewById(R.id.webview) couldn't find the view. But again, what am I doing wrong?? Of course I know I could also instantiate the webview directly from code without the need to specify it from the xml, but I was just wondering what was wrong about this way of doing it. Just in case I also added the following line in my android manifest file: <uses-permission android:name="android.permission.INTERNET" /> I'm not really sure if it's necessary for displaying the webview (I think not) but I just put it there to see if that was the problem, and it turned out it isn't. Thanks Nelson
