See Also: VelocityTracker Members
Helper for tracking the velocity of touch events, for implementing flinging and other such gestures. Use VelocityTracker.Obtain to retrieve a new instance of the class when you are going to begin tracking. Put the motion events you receive into it with VelocityTracker.AddMovement(MotionEvent). When you want to determine the velocity call VelocityTracker.ComputeCurrentVelocity(int) and then call VelocityTracker.GetXVelocity(int) and VelocityTracker.GetYVelocity(int) to retrieve the velocity for each pointer id.
