Android : Differentiate between a flick and swipe

I'm trying to do differentiate between swipe and a flick action. For flick I'm using onFling method of SimpleGestureControl and ACTION_MOVE to detect horizontal swipe. I'm able to achieve the almost desired result but when I do long flick(i.e. touching screen for a bit long) it does take it as flick but my scroll function is also called. How do I differentiate them in a better way?
