onSingleTapConfirmed

Added in API level 3
abstract fun onSingleTapConfirmed(e: MotionEvent): Boolean

Unlike OnGestureListener#onSingleTapUp(MotionEvent), this will only be called after the detector is confident that the user's first tap is not followed by a second tap leading to a double-tap gesture.

Parameters
e MotionEvent: The down motion event of the single-tap. This value cannot be null.
Return
Boolean true if the event is consumed, else false
