RecyclerView remove animation bug

Question

I have implemented a RecyclerView where I can add and delete items. I want the added item to be added on the second last position and, whenever I add a new item, th

Answer 1

Perhaps a bit late, but I was able to fix this in my situation by setting the RecyclerView item animator to null, and then in the setList(list) function of my Adapter scheduling a Transition as such:

Transition transition = new AutoTransition();
transition.setDuration(200); // Or any duration you want
TransitionManager.beginDelayedTransition(mRootViewGroup, transition);

where mRootViewGroup is the viewgroup containing the RecyclerView.

This problem is also fixed by setting your layout_height (or width, depending on the scrolling orientation) to something other than wrap_content, but if, like me, you need your recyclerview height set to wrap_content, this might be a solution for you.

Not certain it will fix your problem as well, but I figured I might as well share what worked for me.

Answer 2

I already reported the problem through Google Issue Tracker here

I hope we can get a fix soon! As you say It seems very related to a possible race condition between the measure updates for the recyclerview and the animation when your recyclerview is wrapping it's content to calculate it's height.

This article explains the problem in a really detailed way also.
