I'm using a RecyclerView. After adding items to the RecyclerView, I need to call:

notifyItemRangeInserted(int positionStart, int itemCount);
However, this shows a sort of "slide down" animation. Is there a way that I can disable this animation?
Thanks.
recyclerView.setItemAnimator(null);
notifyItemRangeInserted(int positionStart, int itemCount);
recyclerView.setItemAnimator(new DefaultItemAnimator());
You can also do it with Data Binding in your xml layout file like this:
<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/my_recycler_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:itemAnimator="@{null}" />
This is possible simply because RecyclerView has a public function called setItemAnimator!
I'm using ListAdapter and Matthew's solution did not work for me, when I re-enable animation it active animation back. I use this if anybody else needed (Kotlin):
recyclerView.itemAnimator = null
adapter.submitList(items.toList()){
    recyclerView.itemAnimator = DefaultItemAnimator()
                SubmitList is asynchronous. You can pass function argument as last parameter and it'll be triggered when list is submitted: adapter.submitList(items.toList()) {     recyclerView.itemAnimator = DefaultItemAnimator() }
