implement segmentUI android

I am trying to implement the segmentUI found in the ios sdk in andro开发者_开发百科id. I have been able to determine that I need to use the radiogroup. My query is how to effectively implement this idea. Appreciate any help.

You need to create 9patch images corresponding to each individual segment, that is, left, center and right and then implement the radiobutton UI which you can position using xml.
