hi,
i'm using GestureDetector to detect double tup actions and having a
little problem when trying to startActivity() inside onDoubleTap
listener.
namely i have observed when onDoubleTap is empty i see the following:
D/GestureActivity( 987): onTouchEvent action=0
D/GestureActivity( 987): onTouchEvent action=1
D/GestureActivity( 987): onTouchEvent action=0
D/GestureActivity( 987): onDoubleTap
D/GestureActivity( 987): onTouchEvent action=1
here action == 0 for ACTION_DOWN, while action == 1 for ACTION_UP
as you can see onDoubleTap is being called after second tups's
ACTION_DOWN and before its ACTION_UP, strange but OK
but when i call startActivity() in onDoubleTap listener i see:
D/GestureActivity( 1019): onTouchEvent action=0
D/GestureActivity( 1019): onTouchEvent action=1
D/GestureActivity( 1019): onTouchEvent action=0
D/GestureActivity( 1019): onDoubleTap
D/GestureActivity( 1019): onPause
as you can see there is missing second ACTION_UP (i think it's because
my main activity is paused and doesn't handle touch events) and when i
return back to my main activity GestureDetector is somehow mislead and
behaves a bit strange
in the end i used onDoubleTapEvent (instead of onDoubleTap) like this:
public boolean onDoubleTapEvent(MotionEvent e) {
if (e.getAction() == MotionEvent.ACTION_UP) {
// start activity here
}
}
and it works OK but i'm still not sure if it's a good solution
any ideas how to use onDoubleTap in my scenario?
