Don't know about that, but you can set `android:tag` on each of the buttons and differentiate them by tags. — Vucko, Aug 06 '16 at 17:25

Toggling through setTag and getTag is one way to do it, probably the simplest.

There are a few ways to directly compare an image...

Can you get drawable? image.getDrawable(), then img1.equals(img2), (you might need a getConstantState() in there)

Bitmap? bmp1.sameAs(bmp2) or pixel by pixel Comparing Bitmap images in Android

thanks @TML, i used set tag and get tag, but still it was more helpful if Android had ImageButton.getBackgroundResource – Shay Zambrovski Aug 07 '16 at 06:05
