Android Listview slow down scroll speed

Question

The scroll speed in the ListView is way too fast for my application. I need to slow it down by a lot.

I can\'t figure out how to do this. The only things I could fin

Answer 1

Yes, there's no easy way. Before API 11, friction was hardcoded inside Scroller, and there's no simple way to change a scrolling view's Scroller. Scroller itself is quite simple, but the mScroller member in AbsListView is private, so you can't just extend ListView.

Answer 2

Verified that this works really nicely for API >= 11:

listView.setFriction(ViewConfiguration.getScrollFriction() * FRICTION_SCALE_FACTOR)

Note that scroll speed decreases as friction increases. To decrease scroll momentum by a suitable amount, I ended up using a friction scale factor of 10. YMMV.
