onTouchEvent
Accepts MotionEvents and dispatches events to a OnRotateListener when appropriate.
Applications should pass a complete and consistent event stream to this method. A complete and consistent event stream involves all MotionEvents from the initial ACTION_DOWN to the final ACTION_UP or ACTION_CANCEL.
Return
true if the event was processed and the detector wants to receive the rest of the MotionEvents in this event stream.
Parameters
event
The event to process
