Android: how to draw ImageButton as pressed until it loses focus?

Once pressed, I would like an ImageButton to continue to draw as if it was pressed until something else is touched. Is there a way to do this short of ex开发者_C百科tending the ImageButton to control how it is drawn, and adding a focus listener to monitor if it loses focus?

Thanks you.

You can use selectors objects instead of bitmaps to give the desired effect in image buttons
