RecyclerView.ItemAnimator

public static abstract class RecyclerView.ItemAnimator
extends Object

Known Direct Subclasses SimpleItemAnimator SimpleItemAnimator A wrapper class for ItemAnimator that records View bounds and decides whether it should run move, change, add or remove animations.

Known Indirect Subclasses DefaultItemAnimator DefaultItemAnimator This implementation of RecyclerView.ItemAnimator provides basic animations on remove, add, and move events that happen to the items in a RecyclerView.

This class defines the animations that take place on items as changes are made to the adapter. Subclasses of ItemAnimator can be used to implement custom animations for actions on ViewHolder items. The RecyclerView will manage retaining these items while they are being animated, but implementors must call dispatchAnimationFinished(ViewHolder) when a ViewHolder's animation is finished. In other words, there must be a matching dispatchAnimationFinished(ViewHolder) call for each animateAppearance(), animateChange() animatePersistence(), and animateDisappearance() call.

By default, RecyclerView uses DefaultItemAnimator.
