Answer 1

I've found the solution in this post.

Drawable dr = this.getResources().getDrawable(R.drawable.warning);
Bitmap bitmap = ((BitmapDrawable) dr).getBitmap();
Drawable d = new BitmapDrawable(this.getResources(), Bitmap.createScaledBitmap(bitmap, 35, 35, true));

txtValue.setCompoundDrawablesWithIntrinsicBounds(d, null, null, null);

Answer 2

I think you can use different size of pics for different screens and use getMinimumWidth to set Bounds.But I did not try it before , may be it is not appropriate for .9 patch.

When you use setCompoundDrawables , you need code like :

Drawable img;
Resources res = getResources();
img = res.getDrawable(R.drawable.btn_img);
//You need to setBounds before setCompoundDrawables , or it couldn't display
img.setBounds(0, 0, img.getMinimumWidth(), img.getMinimumHeight());
btn.setCompoundDrawables(img_off, null, null, null); 

Answer 3

Use setCompoundDrawables() instead of setCompoundDrawablesWithIntrinsicBounds() - you'll have to set the bounds of the drawables manually.
