Either that, or you can implement a custom Button subclass that implements onTouchEvent() to ignore events that are not within some region you define. > Also, an aside, do touch events just get shot directly by the system > into dispatchTouchEvent()?

It is basically a tree traversal, each ViewGroup deciding how to dispatch events to its immediate children. -- Dianne Hackborn Android framework engineer hack...@android.com Note: please don't send private questions to me, as I don't have time to provide private support.
