Answer 1

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);
