How to get drawable from a button?

Looking at : http://developer.android.com/reference/android/widget/Button.html

You can see that

myButton.setCompoundDrawablesWithIntrinsicBounds(Drawable,Drawable,Drawable,Drawable)

Should give you what your looking for.

Order: Left, top, right, and bottom

I think you want Button.getCompoundDrawables()[0]
