Um, I want to use dispatchTouchEvent() to implement a gesture system,
so I have code like this:
public boolean dispatchTouchEvent(MotionEvent ev) {
boolean rtn = mGesture.onTouchEvent(ev);
if (ev.getAction() == MotionEvent.ACTION_UP) {
Log.v("dispatch", "Gesture=" +
mGesture.getGestureString());
if(mGesture.getGestureString().equals("")) {
return super.dispatchTouchEvent(ev);
}
}
return rtn;
}
which means, if the gesture is empty (indicates a click), I want to do
original things like onListItemClick().
But calling super.dispatchTouchEvent(ev); will not trigger
onListItemClick(). So what I want to do is:
If it's a simple click, call onListItemClick().
Otherwise, call dispatchTouchEvent().
Thanks for replying. (Sorry for my poor English since I'm not a native
English speaker)
