“RecyclerView: No Adapter attached; skipping layout” for recyclerview in fragment [duplicate]

Answer 1

Create the adapter and the "non-view" related objects in onCreate. Then use your adapter for the RecyclerView.

Also, clean up your code by initiating the objects in a clear order based on their use and the Activity lifecycle.

public class StatsFragment extends Fragment {

    private RecyclerView mRecyclerView;
    private LinearLayoutManager mLinearLayoutManager;
    private StatsAdapter mAdapter; // was RecyclerView.Adapter mAdapter;
    private String[] myDataset = new String[]{"hello", "world", "yolo"};

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // 1.
        mAdapter = new StatsAdapter(myDataset);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.fragment_stats, parent, false);

        // 2.
        mLinearLayoutManager = new LinearLayoutManager(getActivity());
        mLinearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);

        // 3.
        mRecyclerView = (RecyclerView) v.findViewById(R.id.cardList);
        mRecyclerView.setHasFixedSize(true);
        mRecyclerView.setLayoutManager(mLinearLayoutManager);
        mRecyclerView.setAdapter(mAdapter);

        return v;
    }
}
