Android Question GestureDetector Disabling Panel_Touch?

[mmieher]

I am having trouble with GestureDetector. I stripped down my project to the code below to demonstrate.

The first time I touch either of the panels, the GDPanel_Touch event is fired. However, after
touching both pictures ONCE, the GDPanel_Touch event is only fired the last panel in the view.

If I comment out the GD.SetOnGestureListener, then the GDPanel_Touch event is fired as expected.

The Gesture_onClick event is behaving the same way.

I know one of you Guru's will have the answer!

I have a related issue but want to avoid the ever so embarassing "Please start a new thread for this question."

Syd, changing to Return False makes things worse. Doing so caused the event to not fire at all on either panel after the panel was touched once.

No luck, Syd. The _onTouch event only fires once for the second panel so I cannot detect it and execute your code.
