What you want to do is use this method to create a new bitmap with a matrix that can flip your original bitmap, for example this one:

| -1 0 0 |
|  0 1 0 |
|  0 0 1 |

And here is the code that does just that:

final Matrix m = new Matrix();
m.setValues(new float[] { -1, 0, 0, 0, 1, 0, 0, 0, 1});
final Bitmap normalBitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.arrow);
final Bitmap flippedBitmap = Bitmap.createBitmap(normalBitmap, 0, 0, normalBitmap.getWidth(), normalBitmap.getHeight(), m, true);

Hope this helps.
