Resize Drawable in Android

Question

I am setting a drawable for a progress dialog (pbarDialog) but my issue is I want to resize the drawable each time but can't figure out how.

Here is some code:

Handler progressHandler = new Handler() {      public void handleMessage(Message msg) {         switch (msg.what) {             // some more code             case UPDATE_PBAR:                 pbarDialog.setIcon(mAppIcon);                 pbarDialog.setMessage(mPbarMsg);                 pbarDialog.incrementProgressBy(mIncrement+1);                 break;         }     } };  pbarDialog.show();  Thread myThread = new Thread(new Runnable() {      public void run() {         // some code         for (int i = 0; i < mApps.size(); i++) {             mAppIcon = mAdapter.getIcons().get(mApps.get(i).getPackageName());             // need to resize drawable here             progressHandler.sendEmptyMessage(UPDATE_PBAR);         }         handler.sendEmptyMessage(DISMISS_PBAR);     }  });  myThread.start(); 

Answer 1

The following worked for me:

private Drawable resize(Drawable image) {     Bitmap b = ((BitmapDrawable)image).getBitmap();     Bitmap bitmapResized = Bitmap.createScaledBitmap(b, 50, 50, false);     return new BitmapDrawable(getResources(), bitmapResized); }

Here's where I ended up, thanks in part to Saad's answer:

public Drawable scaleImage (Drawable image, float scaleFactor) {      if ((image == null) || !(image instanceof BitmapDrawable)) {         return image;     }      Bitmap b = ((BitmapDrawable)image).getBitmap();      int sizeX = Math.round(image.getIntrinsicWidth() * scaleFactor);     int sizeY = Math.round(image.getIntrinsicHeight() * scaleFactor);      Bitmap bitmapResized = Bitmap.createScaledBitmap(b, sizeX, sizeY, false);      image = new BitmapDrawable(getResources(), bitmapResized);      return image;  }
