  • Notify a service from a PhoneStateListener

    - by LucaB
    Hi I have built an application that listen to call state changes, and I want to notify a service when the call_state became IDLE. All the components I have are functional, I just need to notify (not start) a service for this. What's the correct practice, maybe using AIDL? Because, in a PhoneStateListener, I can't bind to a service. Do I have to start an activity for that?

  • How do I create an ImageView in java code, within an existing Layout?

    - by Dan T
    I'm looking for an easy way for the user to see how many drinks they've had for a BAC calculator. PICTURE OF THE APP, for reference On button press, I would like an image to be added to the screen, directly under the spinner and with left alignment. When I press the button again, I want another image to be added to the screen. So if I pressed the add beer button, a drawable of a beer would appear below the spinner. If I pressed the add beer button again, I want there to be TWO drawables of beers under the spinner, preferably with them being added from the right. (Also, having them reach their width limit, wrapping around, and starting again on the left, but below a full line, would be AWESOME) I can't figure out how to do this. I assume adding a ImageView in code to a relative layout (because it needs to be positioned to the right) would be the best route, but if it's possible in xml I'd be more than happy to use that. Any help?

  • rotate an image aroound a point

    - by Girish
    Hi all, I have an image which is of rectangular dimension, eg 30 x 60 pixels I want to rotate this image around the bottom center of the image, i.e i want to set the pivot in the above example as (15, 60 )pixel. I am using a drawble and matrix to get this done, whatever i try i always end up rotating around center of the image. Code is : Bitmap bitmapOrg = BitmapFactory.decodeFile("/sdcard/DCIM/2010-06-01_15-32-42_821.jpg"); // float angle = (angle + 10.0f)%360.0f; if(null !=bitmapOrg) { int width = bitmapOrg.getWidth(); int height = bitmapOrg.getHeight(); int newWidth = 15; int newHeight = 15; // calculate the scale - in this case = 0.4f float scaleWidth = ((float) newWidth) / width; float scaleHeight = ((float) newHeight) / height; /* Canvas c = new Canvas(bitmapOrg); float px = ; float py; c.rotate(angle, px, py)*/ // createa matrix for the manipulation Matrix matrix = new Matrix(); // resize the bit map matrix.postScale(scaleWidth, scaleHeight); // rotate the Bitmap // matrix.postRotate(45); // recreate the new Bitmap Bitmap resizedBitmap = Bitmap.createBitmap(bitmapOrg, 0, 0, width, height, matrix, true); // make a Drawable from Bitmap to allow to set the BitMap // to the ImageView, ImageButton or what ever BitmapDrawable bmd = new BitmapDrawable(resizedBitmap); ImageView imageView = new ImageView(this); // set the Drawable on the ImageView imageView.setImageDrawable(bmd); // center the Image imageView.setScaleType(ScaleType.CENTER); // imageView.layout(100, 300, 0, 0); // linLayout.addView(imageView); // add ImageView to the Layout linLayout.addView(imageView, new AbsoluteLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 10, 30 ) ); can anyone let me know how to get this rectified?

  • Intent Bundle returns Null every time?

    - by Max
    I have some extras sent to a new intent. There it grabs the bundle and tests if it is null. Every single time it is null even though I am able to get the values passed and use them. Can anyone see what is wrong with the if statement? Intent i = getIntent(); Bundle b = i.getExtras(); int picked = b.getInt("PICK"); int correct = b.getInt("CORR"); type = b.getString("RAND"); if(b == null || !b.containsKey("WELL")) { Log.v("BUNDLE", "bun is null"); } else { Log.v("BUNDLE", "Got bun well"); } EDIT: Heres where the bundle is created. Intent intent = new Intent(this, app.pack.son.class); Bundle b = new Bundle(); b.putInt("PICK", pick); b.putInt("CORR", corr); b.putString("RAND", "yes"); intent.putExtras(b); startActivity(intent);

  • In an ExpandableListView, how can I show one additional line at the end of the child results?

    - by fiXedd
    I have created a custom ExpandableListAdapter and everything works properly. What I'd like to be able to do is in each of the groups add a different type of child to the end. I have tried adding 1 to the getChildrenCount() number and then testing isLastChild in the getChildView() method, but that doesn't seem to work. If a group has three children what I have working looks like this: Group NormalChild NormalChild NormalChild But I'd really like something like this: Group NormalChild NormalChild NormalChild AlternateChild The idea being that the AlternateChild could be a link to more info about the group. Any Ideas? EDIT: ListView has addFooterView() which will allow you to add a footer to a whole ListView... wonder how to add them to the ExpandableListView's children, or if it's even possible

  • how to listen for changes in Contact Database

    - by hap497
    Hi, I am trying to listen for any change in the contact database. So I create my contentObserver which is a child class of ContentObserver: private class MyContentObserver extends ContentObserver { public MyContentObserver() { super(null); } @Override public void onChange(boolean selfChange) { super.onChange(selfChange); System.out.println (" Calling onChange" ); } } MyContentObserver contentObserver = new MyContentObserver(); context.getContentResolver().registerContentObserver (People.CONTENT_URI, true, contentObserver); But When I use 'EditContactActivity' to change the contact database, My onChange function does not get called.

  • Checkbox 'Checked' in ListView is restored after scrolling

    - by adrianrdzv
    I'm having the following problem: I have a ListActivity, which its ListView is composed by an icon, text and a checkbox (using LayoutInflater). The Adapter for the ListView extends ResourceCursorAdapter (i.e. the data source of the ListView is retrieved from a database, also the Checked status of each row) Everything works pretty Ok, except when I uncheck/check the checkbox in any row, if I scroll down until the modified checkbox is no longer visible, and then scroll up, the checkbox is restored to its original state. The database IS modified, this is not the problem (i.e. if I modify a row and exit the activity, and enter again, the modified row is displayed Ok). My guess is that this has something to do on how the list is rendered because for some reason the ListView "renders" the original state of all rows when it was first populated when scrolling. I've been looking around for this bug but I don't find anybody that had this problem. I appreciate any advice you have.

  • Drawing a bitmap in a canvas after calling setBitmap doesn't work

    - by kodbar_k
    I'm drawing a bitmap in a canvas and i want to have the result in a new bitmap, but i still have a black screen as result. This is my code, part of the onDraw(Canvas canvas) method : if (bitmapTemplate == null) { canvasBis = new Canvas(); bitmapTemplate = Bitmap.createBitmap(canvas.getWidth()+30,canvas.getHeight(),Bitmap.Config.ARGB_8888); drawZones(canvasBis,bitmapTemplate); } bitmapRes = Bitmap.createBitmap(canvas.getWidth()+30,canvas.getHeight(),Bitmap.Config.ARGB_8888); canvas.setBitmap(bitmapRes); canvas.drawBitmap(bitmapTemplate, matrix, null); My goal is to have a new bitmap (bitmapRes) by applying a matrix on an existing bitmap (bitmapTemplate). With this code i alway have a black screen, but when i remove the line canvas.setBitmap(bitmapRes) i have a result but not in a new bitmap. any ideas please ? Maybe transparency ? Thanks in advance. drawZones draws some zones in bitmapTemplate.

  • Last time the contact was modified

    - by Bostjan
    Hey, is there a way to find out the last time a contact was modified? I can't seem to find a variable for it. The reason I'm asking is because I'd like to do a sync of the contacts to my web server and I don't feel like checking for each contact with a HTTP request if it needs updating. So I was thinking to check the date of the last update to the date of the last sync.
