  • Android service puts multiple instances of an activity in the history

    - by HenryAdamsJr
    I'm making a music player. When you press play, it loads a notification into the OnGoing section. When you go anywhere else in the system, I want the music to keep playing. All of this is fine. The problem is that when I relaunch my activity from the Notification, it adds a task to the history stack each time, so if I hit back, I have to see the instance of Activity B from where I pressed play, and from every time I clicked on the notification to go back to Activity B. I want the instance of Activity B that I launch from the notification (via the service) to be the only copy of that Activity in the history. I've been playing around with various Intent flags and Activity attributes in the manifest, but I haven't found the proper combination.

  • Android font out of view on small screen

    - by user581949
    Hi Everyone I have several text views that take up the majority of the screen in landscape view in a relativelayout and the font size i have set is quite big (150dp). The text views are all timers and the furthest to the right is the "seconds" textview. My problem is that when testing on a phone with a small screen res the seconds are way outside the limit of the screen and can't be seen. They are in perfect place on normal to large screen resolutions just not on a small screen. Is there any way i can force the "seconds" text view to stay on screen, without adjusting the font size or margins between each text view? Even if it means looking cramped on a small screen i can live with that. Any help is greatly appreciated. Thanks This is the corresponding code:

    - by Asahi
    I'd like to recognize arrival of new MMS msg (after it is downloaded to inbox). I am doing the following: private MMSContentObserver mMmsCO; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); h = new Handler(); mMmsCO = new MMSContentObserver(h); getContentResolver().registerContentObserver (Uri.parse("content://mms"), true, mMmsCO); } where private class MMSContentObserver extends ContentObserver { public MMSContentObserver(Handler h) { super(h); } @Override public boolean deliverSelfNotifications() { return false; } @Override public void onChange(boolean selfChange) { super.onChange(selfChange); } } However, onChange is not getting called.

    Team, I need to run a background thread in my application. Could you please share the best practices where to initiate the thread so that keeps running irrespective of the Activity is being shown and things to consider.

  • Android menu view, gridview or something else?

    - by dfilkovi
    I need to create a home screen (menu) with four to six items arranged in a grid view, each item needs to have an icon and a text below the icon. I googled and everything I could find were adapterView examples, with dynamic menu loading, and I want to make it with static xml, this view will not change so no need for dynamic code. Can anyone post an xml example of this?

  • Android SharedPreferences set True or False - Clear on App Exit

    - by KickingLettuce
    I want a notification to pop up when an app opens. But once User dismisses, I don't want it to come back again, even if they go back to the same activity. But when the app exits, and they come back later, I want same dialog notification to pop up (prompting user to login). So basically... boolean b = true; if (b == true) { // show dialog b = false; } I simply want var b to save state but clear on exit.

  • Iterating ListView items in Android

    - by pocoa
    I want to iterate a list of items into a ListView. This code below is not enough to iterate all the items into the list because of the weird behaviour of getChildCount() function which only returns the visible item count. for (int i = 0; i < list.getChildCount(); i++) { item = (View)list.getChildAt(i); product = (Product)item.getTag(); // make some visual changes if product.id == someProductId } My screen displays 7 results and when there are more than 7 items into the list, it's not possible to access to the 8th item or so.. Only visible items.. Should I use ListIterator instead? Thanks.

  • Android app crashes on second run

    - by Nick
    I have been working on my app and it runs on the simulator fine. I loaded it into my phone and now I have a problem. It runs fine when I first start it and also if I pick home and then restart it; however, if I use the back arrow and then restart it it crashes on that time, but will work out the next time I start it. I think it has to do with some kind of memory build up, but I verified onDestroy is being called, I figured that deletes everything my program created, right?

  • android listview order changed when called notifyDataSetChanged

    - by 9nix00
    hi,all. when I use notifyDataSetChanged(), the listview display order will be change . like this 3 2 1 when current activy was created. but when I change the data. it will be 1 2 3 I don't want the order changed and i dont understand why its happening. This is a piece of code from my adapter class public static class ItemAdapter extends BaseAdapter { private String[] mData; private LayoutInflater mInflater; // I called this method to change data public void setEditText(int position, final String item) { mData[position] = item; notifyDataSetChanged(); } } I change data at some dialog like this builder = new AlertDialog.Builder(ct); builder.setTitle(R.string.pickStatus) .setView(edBuffer) .setPositiveButton(R.string.save, new DialogInterface.OnClickListener() { @Override public void onClick( DialogInterface dialog, int id) { // TODO Auto-generated method stub canPop = true; final String tmp = edBuffer.getText().toString(); KbonezLog.e(String.format( "set into key %d", key)); //use mData key to set value setEditText(key, tmp); dialog.dismiss(); }})

  • Override onDraw to change how the drawing occurs (Android)

    - by Casebash
    I want to change how my UI elements display, so I am overriding onDraw. The following code allows me to change a View to be drawn using PorterDuff.Mode.DARKEN. Unfortunately, this method involves creating a bitmap the size of the entire screen, then drawing to it then drawing this large bitmap the main screen again, for each UI element. This isn't at all efficient. Is it possible to achieve this in a more effecient way? @Override protected void onDraw(Canvas canvas) { //TODO: Reduce the burden from multiple drawing Bitmap bitmap=Bitmap.createBitmap(canvas.getWidth(), canvas.getHeight(), Config.ARGB_8888); Log.e("tmp",canvas.getClipBounds().toString()); Canvas offscreen=new Canvas(bitmap); super.onDraw(offscreen); //Then draw onscreen Paint p=new Paint(); p.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.DARKEN)); canvas.drawBitmap(bitmap, 0, 0, p); }

  • Stacking Dialogs in Android

    - by ChaimKut
    Is there a way to control the relative stacking of Dialogs produced by your own Activity? For instance, there are some more important Dialogs which I would like to ensure are on top and if another Dialog wants to pop up I would want it to pop under the important Dialogs. Example: I want to present to the user an important dialog, Dialog A. The activity realizes that there is a dialog, Dialog B, of lesser importance to display to the user. Is it possible to specify Dialog B to be under Dialog A so that when Dialog A is cleared, Dialog B will be seen by the user? I know that the onDismiss interface exists, but this necessarily ties Dialog A and Dialog B together. I want the Dialogs to be independent and would prefer to use a higher level abstraction like the window stack responsible for ordering the Dialogs.
