I don't believe there's any way to do this with stock Buttons. What you probably want to do is to extend a View into your own custom class, and override the onDraw method to draw the pie chart with whatever algorithm you want to use to draw a segmented circle.

Then on onTouch you can compare the touch X/Y coordiante versus the pie segments you drew and then do some action based on which segment of the pie was clicked.
