Where are the options to control a Button's background?

I would have thought that there would be a variety of options in connection with a button's background from an image, for example the image could be tiled, or stretched or centred etc etc, but when I list a button's methods I can't see anything. Now I'm suspecting that it could be a two stage process, perhaps getting some kind of view first and then using a method of that view. Or maybe there is simply no control whatsoever concerning a button background. Please advise.

Note that any View's background is something that fills the area covered by that View, so you can't have it centered.

Stretching the the default behaviour, that's why a state list of 9-patches the the best thing to use for Button's background.

If you want tiled background, you may use XML Bitmap with tileMode="repeat". See also other kinds of Drawables on this site. You can for example make something that feels like centered background image using Inset Drawable.

And finally the functions are there: setBackgroundDrawable and setBackgroundResource.
