canReuseUpdatedViewHolder
When an item is changed, ItemAnimator can decide whether it wants to re-use the same ViewHolder for animations or RecyclerView should create a copy of the item and ItemAnimator will use both to run the animation (e.g. cross-fade).
Note that this method will only be called if the ViewHolder still has the same type (getItemViewType). Otherwise, ItemAnimator will always receive both ViewHolders in the animateChange method.
If your application is using change payloads, you can override canReuseUpdatedViewHolder to decide based on payloads.
Return
True if RecyclerView should just rebind to the same ViewHolder or false if RecyclerView should create a new ViewHolder and pass this ViewHolder to the ItemAnimator to animate. Default implementation returns true.
Parameters
The ViewHolder which represents the changed item's old content.

True if RecyclerView should just rebind to the same ViewHolder or false if RecyclerView should create a new ViewHolder and pass this ViewHolder to the ItemAnimator to animate. Default implementation calls canReuseUpdatedViewHolder.
