NullPointerException - Attempt to invoke virtual method RecyclerView$ViewHolder.shouldIgnore()' on a null object reference

Question

Several developers have reported seeing the following stack trace since upgrading to Android Support 23.2.0:

java.lang.NullPointerException: Attempt to invok         


        

Answer 1

I also encountered into this issue, even with version of RecyclerView 27.1.1. And I had the following code in my project:

    recyclerView.setLayoutManager(mLayoutManager);
    SimpleItemAnimator itemAnimator = new DefaultItemAnimator();
    itemAnimator.setSupportsChangeAnimations(false);
    recyclerView.setItemAnimator(itemAnimator);
    LayoutInflater inflater = LayoutInflater.from(getContext());

And I've fixed it after removing addition of Animator to RecyclerView, i.e. this code started to look the following way:

    recyclerView.setLayoutManager(mLayoutManager);
    LayoutInflater inflater = LayoutInflater.from(getContext());
