abstract class SimpleItemAnimator : RecyclerView.ItemAnimator
kotlin.Any
   ↳ androidx.recyclerview.widget.RecyclerView.ItemAnimator
   ↳ androidx.recyclerview.widget.SimpleItemAnimator

A wrapper class for ItemAnimator that records View bounds and decides whether it should run move, change, add or remove animations. This class also replicates the original ItemAnimator API.

It uses RecyclerView.ItemAnimator.ItemHolderInfo to track the bounds information of the Views. If you would like to extend this class, you can override obtainHolderInfo() method to provide your own info class that extends RecyclerView.ItemAnimator.ItemHolderInfo.
