Disable animation on notifyItemRangeInserted()

Question

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.

Answer 1

try clearing the RecyclerView item animator

recyclerView.setItemAnimator(null); 

you can re-enable your animation after if needed.

recyclerView.setItemAnimator(null); notifyItemRangeInserted(int positionStart, int itemCount); recyclerView.setItemAnimator(new DefaultItemAnimator()); 

Answer 2

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!
