I have implemented the nested recyclerview inside the list.how to fetch data from the inner recyclerview in the main class or doing calculation of the int value provided for the inner recyclerview.
1.Heterogeneous Recyclerview with multiple views.

public class ViewHolderRadio extends RecyclerView.ViewHolder {

how to fetch value of the inner recyclerview inside the class in which main recyclerview is inflated.
