How do detect onfling inside onscroll in android?

The problem is I would like to call some function when onscroll is firing
but not onfling. However, I found that if the onfling is trigger , it
comes with the onscroll. I notice the difference between them is onscroll
+ tapUp = onfling.
So I would like to detect the following case:
Inside onscroll listener:
if not tap up then run some function
How to achieve this? thanks
