Recyclerview No adapter attached skipping layout

Question

I replaced ListView with RecyclerView in my code. Everything works fine but an error message is shown.

15:25:53.476 E/RecyclerView: No adapter attached; skipping layout

15:25:53.655 E/RecyclerView: No adapter attached; skipping layout

Code:

ArtistArrayAdapter adapter = new ArtistArrayAdapter(this, artists);
recyclerView = (RecyclerView) findViewById(R.id.cardList);
recyclerView.setHasFixedSize(true);
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new LinearLayoutManager(this));

Why do I keep getting this error?

Answer 1

Check if you are calling these statements from the "main" thread outside of a delayed asynchronous callback.
Call the code below in your fragment from inside a ResultCallback method. 

LinearLayoutManager llm = new LinearLayoutManager(this);
llm.setOrientation(LinearLayoutManager.VERTICAL);
list.setLayoutManager(llm);
list.setAdapter( adapter );

Move the code to the onConnected() method within my app. 

I hope this helps.
