"recyclerview: No Adapter Attached; Skipping Layout" For Recyclerview In Fragment

I'm getting this error but I don't know what is causing it...perhaps something to do with the fact that this is being initialized in a fragment and not in the activity itself. Edit

Solution 1:

Move your setLayoutManager line before setAdapter

Solution 2:

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.

publicclassStatsFragmentextendsFragment {

    privateRecyclerView mRecyclerView;
    privateLinearLayoutManager mLinearLayoutManager;
    privateStatsAdapter mAdapter; // was RecyclerView.Adapter mAdapter;privateString[] myDataset = newString[]{"hello", "world", "yolo"};

    @OverridepublicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // 1.
        mAdapter = newStatsAdapter(myDataset);
    }

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

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

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

        return v;
    }
}

Solution 3:

One way to fix this issue is to attach an empty adapter to the RecyclerView

voidinitializeRecyclerView() {

   recyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
   recyclerView.setAdapter(new SampleAdapter(getCurrentActivity()));
   recyclerView.setLayoutManager(new LinearLayoutManager(getCurrentActivity()));
   recyclerView.setHasFixedSize(true);
}
