Android: How to detect when a scroll has ended

Question

I am using the onScroll method of GestureDetector.SimpleOnGestureListener to scroll a large bitmap on a canvas. When the scroll has ended I want to redraw the bitmap in case

Answer 1

SimpleOnGestureListener.onFling() 

It seems to take place when a scroll ends (i.e. the user lets the finger go), that's what I am using and it works great for me.
