How to know the vertical scrolling direction in android i.e. upward or downward

Question

Is there any way to determine that Android (vertical) scroll-view is scrolled upward or downward. I actually have a scenario to implement it.

Answer 1

The onScrollChanged event will fire, and you can compare the previous and current scroll positions. See here: http://developer.android.com/reference/android/view/View.html#onScrollChanged%28int,%20int,%20int,%20int%29
