Recyclerview not call onCreateViewHolder

Question

My RecyclerView does not call onCreateViewHolder, onBindViewHolder even MenuViewHolder constructor, therefore nothing app

Answer 1

In my case, my list size was 0 and it was not calling the onCreateViewHolder method. I needed to display a message at center for the empty list as a placeholder so I did it like this and it worked like charm. Answer by @Konstantin Burov helped.

  @Override
public int getItemCount() {
    if (contactList.size() == 0) {
        return 1;
    } else {
        return contactList.size();
    }
}
