Creating a stepped seek bar

How can I create a stepped seek bar for an android interface, one that functions like the seek bar in the men开发者_开发知识库u below.

I think you could use the RatingBar widget with some clever graphics. The other option is to Make your own widget, maybe starting with a subclass of SeekBar and implementing some sort of snapping to integer values (in the change listener).
