No adapter attached; skipping layout

Question

logcat error : No adapter attached; skipping layout

I changed the context argument with getActivity(), but the app is still not running.

public class FragmentActivity extends Fragment {  
    private RecyclerView mRecyclerView;
    private CountryAdapter mAdapter;
    private LinearLayoutManager layoutManager;
    public FragmentActivity(){}
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.activity_main, container, false);
        mRecyclerView = (RecyclerView) rootView.findViewById(R.id.list);
        layoutManager = new LinearLayoutManager(getActivity());
        mRecyclerView.setLayoutManager(layoutManager);
        mRecyclerView.setAdapter(mAdapter);
        mAdapter = new CountryAdapter(CountryManager.getInstance().getCountries(), R.layout.card_layout, getActivity());
        return rootView;
    }
    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
    }
}

Answer 1

You didn't attach the adapter because you create it after you try to attach it:

mRecyclerView.setAdapter(mAdapter); // Here, mAdapter is null
mAdapter = new CountryAdapter(CountryManager.getInstance().getCountries(), R.layout.card_layout, getActivity());
