I have no knowledge of this crash from where it is occurring. Any help would be greatly appreciated. I am neither using "android:animateLayoutChanges="true"

Basically i had tried to merge these two different GitHub project,

rv-adapter-states

rv-adapter-endless

My files links are as follows from pastbin,

Row Layout

Code of recyclerview

My Adapter merge from two diffrent adapter of rv

Main adapter

Answer 1

I had the same problem and I don't know why is happening.

I solved it removing the android:animateLayoutChanges on the recyclerview and to animate the recyclerview I have added: recyclerView.setItemAnimator(new DefaultItemAnimator());

Take an account to add the method public long getItemId(int position) and set setHasStableIds(true) if you want animate it.

Answer 2

Have you tried layoutManager.setItemPrefetchEnabled(false);? It worked for me.
