I have been using SectionedRecyclerViewAdapter from https://github.com/luizgrp/SectionedRecyclerViewAdapter. It is working great. I would like to start adding some animations. I downloaded and installed the test/example app, and inspected the code for the animation example. I cannot understand what part of the code for the example makes the animations work as they do. Can anyone explain it?
Animations are triggered when any of the notify methods of the RecyclerView.Adapter are called. In the example below the RecyclerView will animate the insertion of an item in a specific position:
adapter.notifyItemInserted(position);
The library provide extra notify methods to help trigger the animation for specific items of the sections, like this one.
