  • Android ExpandableListView From Database

    - by SterAllures
    I want to create a two level ExpandableListView from a local database. The group level I want to get the names from the database Category table category_id | name ------------------- 1 | NameOfCategory the children level I want to get the names from the List table list_id | name | foreign_category_id -------------------------------- 1 | Listname | 1 I've got a method in DatabaseDAO to get all the values from the table public List<Category> getAllCategories() { database = dbHelper.getReadableDatabase(); List<Category> categories = new ArrayList<Category>(); Cursor cursor = database.query(SQLiteHelper.TABLE_CATEGORY, null, null, null, null, null, null); cursor.moveToFirst(); while(!cursor.isAfterLast()) { Category category = cursorToCategory(cursor); categories.add(category); cursor.moveToNext(); } cursor.close(); return categories; } Now adding the names to the group level is easy I do it the following way: ArrayList<String> groups; for(Category c : databaseDao.getAllCategories()) { groups.add(c.getName()); } Now I want to add the children to the ExpandableListView in the following array ArrayList<ArrayList<ArrayList<String>>> children;. How do I get the children under the correct group name? I think it has to do somenthing with groups.indexOf() but in the list table I only have a foreign category_id and not the actual name.

  • Receiving a NullPointerException when calling a cursor in Android

    - by LordSnoutimus
    I am creating an application which tracks the users location using GPS, stores the longitude and latitude in a database using a content provider then output the first long and lat to a mapview. I am able to create the cursor using this line of code: Cursor c = getContentResolver().query(GPSContentProvider.CONTENT_URI, null, null, null, null); startManagingCursor(c); However, when I make a call to move to the first row in the database or even try to close the cursor using c.close(); I receive a NullPointerException.

  • Android, NetworkInfo.getTypeName(), NullpointerException

    - by moppel
    I have an activity which shows some List entries. When I click on a list item my app checks which connection type is available ("WIF" or "MOBILE"), through NetworkInfo.getTypeName(). As soon as I call this method I get a NullpointerException. Why? I tested this on the emulator, cause my phone is currently not available (it's broken...). I assume this is the problem? This is the only explanation that I have, if that's not the case I have no idea why this would be null. Here's some code snippet: public class VideoList extends ListActivity{ ... public void onCreate(Bundle bundle){ final ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); ... listview.setOnItemClickListener(new OnItemClickListener(){ public void onItemClick(AdapterView<?> parent, View view, int position, long id) { ... NetworkInfo ni = cm.getActiveNetworkInfo(); String connex = ni.getTypeName(); //Nullpointer exception here if(connex.equals("WIFI")doSomething(); } }); } }

  • How to get current location with an accept accuracy in Android

    - by virsir
    I am trying to locate user's device to get its current location with coarse method. The problem is that I can only accept a location with accuracy of 1000m, my code like this: public void onLocationChanged(Location location) { currentLocation = location; if(location.hasAccuracy()) { if(location.getAccuracy() < 1000) { locationManager.removeUpdates(this); callback(); //do callback here } } } But what if the network is not good and I can not get the location with that accuracy? I may want to accept the latest location I got if I have requested its location for some time, like 1 minute. Then how can I control the request time, for example, 1 minute, if it did not get the accurate location until then, I will stop it and then accept the latest location I have got if exist.

  • Android WebViewClient problem

    - by deSelby
    I've defined a private class that extends WebViewClient and set my WebView's client to an instance of that class (webView01.setWebViewClient(new Callback());). The class definition is as follows: private class Callback extends WebViewClient { public void onLoadResource (WebView view, String url) { } public void onPageStarted (WebView view, String url, Bitmap favicon) { } public void onPageFinished (WebView view, String url) { Animation anim = AnimationUtils.loadAnimation(MyNews.this, R.anim.webviewanim); view.startAnimation(anim); } public void onReceivedError (WebView view, int errorCode, String description, String failingUrl) { } public boolean shouldOverrideUrlLoading (WebView view, String url) { Log.e("loading url", url); return false; } } My problem is that onPageFinished is definitely getting called, but shouldOverrideUrlLoading is never being called. What am I doing wrong here?

  • Android Emulator and adb problems

    - by Richard
    I'm having a problem in that whenever I start a emulator, either manually through the command line, or when debugging from Eclipse, it is never recognized by adb, i.e. 'adb devices' will not list it. I have to manually kill and restart adb every time I want to recognize a new emulator. Surely, something is wrong here? (I'm on Vista 64-bit)

  • Android: View.getTag/setTag and IllegalArgumentException

    - by Sparafusile
    Yes, I know you need a unique resource id when calling the version of these functions that requires a key, but I cannot for the life of me figure out how to create a resource id that can be used in this way. A final variable in my class wont work and neither will a hard coded value. Both threw an IllegalArgumentException. So what gives, how do you use these methods? Spara

  • Android: Deciding between SurfaceView and OpenGL (GLSurfaceView)

    - by Rich
    Is there a way to decide up front based on the expected complexity of a game/app in the planning phase whether to use regular Canvas drawing in a SurfaceView or to go with OpenGL? I've been playing around with a Canvas and only need 2D movement, and on a fairly new phone I'm getting pretty decent performance with a bunch of primitive objects and a few bitmaps running around the screen on a solid background. Is it fair to say that if I'm going to be drawing background images and increasing the number of objects being moved and drawn on top of them that I should go straight to OpenGL?

  • How to customize android analog clock widget through configuration screen

    - by michJ
    I'm trying to develop my own analog clock widget on the home screen. It's based on the stock ICS analog clock widget, but when added to the homescreen, my widget opens a configuration screen first. On this screen you can choose the color you want the clock to be (through a colorpicker dialog). You also see a preview of the clock in the chosen color on this screen. (See picture). My problem is changing the color of the widget on the home screen to the chosen color (when you hit the apply button). I have three .png files that I use for the dial, hour hand and minute hand. I color them using this code in my widgetconfig class: Drawable dial = getResources().getDrawable(R.drawable.clockbackground); dial.setColorFilter(color, PorterDuff.Mode.MULTIPLY); //hour Drawable hour = getResources().getDrawable(R.drawable.hourhand); hour.setColorFilter(color, PorterDuff.Mode.MULTIPLY); //minute Drawable min = getResources().getDrawable(R.drawable.minutehand); min.setColorFilter(color, PorterDuff.Mode.MULTIPLY); // clock AnalogClock clockpreview = (AnalogClock) findViewById(R.id.ACconfig); clockpreview.setBackgroundDrawable(dial); This works fine because I can find the AnalogClock since it's in the layout xml file of the configuration screen, which I set in the OnCreate() through setContentView(). The problem is that for the clock widget on my screen I have to use RemoteViews. So I tried setting the new background of the clock widget through RemoteViews. But RemoteViews seems too limited to do this. I need something like setTextViewText() but then for the background of my analog clock widget, like for example: RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.clockwidget); views.setAnalogClockBackgroundDrawable(dial); The clock widget background seems sort of unchangeable. How can I recolor my clockwidget on homescreen in widgetconfig class? There must be a way because it seems so easy to do at first... My project consists of the widget config class and clockwidget class, widgetconfig.xml, clockwidget.xml, and widget_info.xml (for appwidgetprovider).

  • Android ViewFlipper is out of control

    - by Doug Miller
    I have an app that uses a ViewFlipper to display some text and images. I have the flipper's flipinterval set to 10 seconds, but also want to allow the user to click a button that will advance the flipper. The code blow works great on 2.2, the view is changed every 10 seconds and if I click flip_button the view is changed and the auto flip steps back in 10 seconds later. The 1.5 and 1.6 versions will remember the manual advance and it will happen every time in the rotation. What am I missing? private void initFlipButton(){ final ImageView flip_button = (ImageView) findViewById(R.id.flip_button); info_button.setOnClickListener(new View.OnClickListener() { public void onClick(View view) { flipper.stopFlipping(); flipper.showNext(); flipper.startFlipping(); } }); } private void initFlipper(){ flipper = (ViewFlipper) findViewById(R.id.flip_dog); flipper.setFlipInterval(10000); flipper.setInAnimation(inFromRightAnimation()); flipper.setOutAnimation(outToLeftAnimation()); flipper.startFlipping(); }

  • Change the playback rate of a track in real time on Android

    - by android_dev
    Hello, I would like to know if somebody knows a library to changing the playback rate of a track in real time. My idea is to load a track and change its playback rate to half or double. Firstly, I tried with MusicPlayer but is was not possible at all and then I tried with SoundPool. The problem is that with SoundPool I can´t change the rate once the track is loaded. Here is the code I am using (proof of concept): float j = 1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button b = (Button)findViewById(R.id.Button01); b.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { j = (float) (j +.5); } }); AssetFileDescriptor afd; try { SoundPool sp = new SoundPool(1, AudioManager.STREAM_MUSIC, 0); afd = getAssets().openFd("wav/sample.wav"); int id = sp.load(afd, 1); sp.play(id, 1, 1, 1, 0, j); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } When I press the button, the playback rate should increase but it does not happen. Any idea of how change the rate in real time? Thanks in advance.
