Recyclerview not call onCreateViewHolder

Question

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

Answer 1

For me, it was because the setHasStableIds(true); method was set. Remove that and it will work

Answer 2

If using a custom adapter do not forget to set the ItemCount to the size of your collection.

Answer 3

Please set layout manager to RecyclerView like below code:

RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view_right);
//set your recycler view adapter here
NavigationAdapter adapter = new NavigationAdapter(this, FragmentDrawer.getData());
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new LinearLayoutManager(this));

Answer 4

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();
    }
}

Answer 5

Maybe it helps someone but if you set your RecycleView's visibility to GONE the adapter methods won't be called at all... Took me some time to figure it out.

Answer 6

In my case I set the ID of my RecyclerView to "recyclerView". It seems that this ID was already defined somewhere, because when I changed that to different ID, the methods from the adapter were called properly.
