logcat错误：没有连接适配器;跳过布局

我用getActivity()更改了context参数,但应用程序仍未运行.

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);    }}

解决方法:

您没有附加适配器,因为您在尝试附加它后创建它：

mRecyclerVIEw.setAdapter(mAdapter); // Here, mAdapter is nullmAdapter = new CountryAdapter(CountryManager.getInstance().getCountrIEs(), R.layout.card_layout, getActivity());
