Wish in (visual) can load one image for button set BitmapDrawable

Wish:
in (visual) designer can load one image for button set BitmapDrawable
because, in designer have 3 images obligated and are statelistdrawable, and not can trasferrer the brackground imagemap (for button) to others controls

You can use an ImageView instead of a button in that case. The result will be the same.
