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 find in the documentation are a “setFriction” function which is only supported in API Level 11, and a static “getScrollFriction” method which can’t be overridden and has no corresponding setter.
What’s the trick here – how do I control the scroll speed?
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.
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 itself is quite simple, but the
mScroller member in
AbsListView is private, so you can’t just extend
