recyclerview No adapter attached; skipping layout

Just implemented RecyclerView in my code, replacing ListView.

Everything works fine. The data is displayed.

But error messages are being logged:

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

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

for the following code:

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

As you can see I have attached an adapter for RecyclerView. So why do I keep getting this error?

I have read other questions related to the same problem but none of them help.

Solution

  • Can you make sure that you are calling these statements from the "main" thread outside of a delayed asynchronous callback (for example inside the onCreate() method). As soon as I call the same statements from a "delayed" method. In my case a ResultCallback, I get the same message.

    In my Fragment, calling the code below from inside a ResultCallback method produces the same message. After moving the code to the onConnected() method within my app, the message was gone...

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