body: <p>How can I animate the RecyclerView Items when there are appearing?</p>
  
  <p>The default item animator only animates when a data is added or removed after the recycler data has been set. I'm new developing applications and don't have any clue where to start.</p>
  
  <p>Any ideas how to achieve this?</p>
