What is Expandable RecyclerView in Android

Expandable RecyclerView

Expandable RecyclerView is one of the most important feature in Android which can be easily created for our application .

It contains two views one is parent view and other is child view. Parent is visible by default but the child view has to be expanded and collapsed. It will expand when we click on parent view.
