I am able to read flings in left or right directions on a listview and
change that listview to a different listview. To do this I over rode
onTouchEvent like the example above. The problem is that in order to
detect a fling onTouch has to return true and consume the touch event.
Once it returns true the listview's onclick behavior no longer works -
in other words you cannot indicate to a user which list item was
touched.
public boolean onTouchEvent(MotionEvent event){
if (mGestureDetector.onTouchEvent(event)) {
return true;
}
return super.onTouchEvent(event);
}
Also for fling to be detected, Gesturedetector's onDown should return
true.
