Android button doesn't react

I'm facing a tough problem right now regarding the simplest thing: a Button.

I have a big application where i need multitouch capabilities embedded in a custom joypad-like interface. For this interface i have a custom joystick and buttons. The problem is this buttons receive the touch event but don't give the usual visual feedback (changing color while touched). These buttons are simple extensions of the base Button class.

Any ideas on why this happens? I'm doing the event separation myself for multitouch but this isn't the issue as the Buttons receive the event as expected.

I开发者_如何学Cf code needed, comment please.

Thanks in advance, JQCorreia

You need to create and use custom StateListDrawables for your buttons.
