[android help] Set the side of an image when using android:drawable____ in a button

If you want to define the accuracy size of the drawable, You should use Java code instead of android:drawableLeft

  Drawable dw = getResources().getDrawable(R.drawable.ic);
  dw.setBounds(0, 0, 100, 100); // set the size of the drawable to 100*100

  button.setCompoundDrawables(dw, null, null, null);

because of

 android:drawableLeft // equals with  setCompoundDrawablesWithIntrinsicBounds

and

 android:drawablePadding // this used to control the padding between the text and drawable
