Android: custom button shape

Question

I'm trying to achieve a custom controller containing of various buttons in different shapes. I'm wondering how I can achieve this with Android.

The result should look similar like this, where every color is a different button.

I suppose I have to subclass View so please don't write that as an answer ;-) Please give some methodical steps what's needs to be implemented, like drawing, sensing touches, etc or maybe point me to some examples (if exist).

Thanks

Answer 1

if you intend to draw this dynamically you would have to extend View and override onDraw, you can implement onTouchListeners, etc to detect when and where people are touching it.

I found this document explaining everything in detail and having links pointing to related topics.
