The ItemAnimators library comes with a huge collections of pre-created animators for your RecyclerView. It was created so developers can easily animate their RecyclerView. These Animators correctly work with all view states and RecyclerView states (as the DefaultItemAnimator does)

DISCLAIMER: this library does not animate items on scroll, just when added, removed, moved, or changed

implementation "com.mikepenz:itemanimators:1.1.0"
implementation "androidx.recyclerview:recyclerview:${androidXVersion}"

To use appcompat please use a version smaller than 1.1.0. (See the releases on GitHub)

//just provide the animator to your RecyclerView
mRecyclerView.setItemAnimator(new ScaleUpAnimator());
//now it will automatically take care of all animations when you add, remove, chanage, move items
//It is very important that you use the correct notify methods if items were changed, otherwise the adapter can't animate the items
//Read more: https://developer.android.com/reference/android/support/v7/widget/RecyclerView.Adapter.html#notifyDataSetChanged()
//If you want those things out of the box have a look at the **FastAdapter** it handles everything correctly for you
