Unfortunately Android's multitouch design is completely idiotic and does not allow multitouch events to go to two different views at the same time. You can only capture multitouch on *one* view.
I guess in Android 3.2 they now allow multitouch to go the multiple views. But I have not tested it. Whoever thought of the one view thing is a moron, period. It should have just worked. But noooooo. We are Google we do everything the hard way. -niko On Nov 28, 8:13 am, ColletJb <[email protected]> wrote: > Hi, > > I'm facing an very simple (and stupid) issue and I hope someone will > be able to provide me an explanation... > > I'm trying to develop an Activity with 2 buttons (let's call them btnA > and btnB), they are in my xml layout.
