RecylerView Animation

RecylerView Animation

In earlier tutorials we had learned implementation of RecyclerView. Now in this tutorial we will move to RecyclerView Animation part. The best thing of RecyclerView is that it provide inbuilt animations but the ListView and GridView don’t provide inbuilt animation. Now to implement the Animation in RecyclerView it provide some methods that we need to use:

  1. notifyItemRemoved(position) : While removing item from RecyclerView we need to call this method, this method will remove the item from particular position with animation.
  2. notifyItemInserted(position) : If you want to insert item then you need to call this method, this method will insert the item at particular position with animation.
  3. notifyItemChanged(position) : When you want to change row item with any other item then you need to call this method, this method will change the item at particular position.

Example

In this tutorial, we are going to learn how to use implement RecyclerView Animation.
