Answer 1

you should know that if you return false for action_down , you will not get any further actions regarding this touch event

https://developer.android.com/training/gestures/detector#capture-touch-events-for-an-activity-or-view

"Beware of creating a listener that returns false for the ACTION_DOWN event. If you do this, the listener will not be called for the subsequent ACTION_MOVE and ACTION_UP string of events. This is because ACTION_DOWN is the starting point for all touch events."
