LinearLayoutManager 无法解析 getOrientation()

LinearLayoutManager cannot resolve getOrientation()

我在一个片段中实现了 RecyclerView,我正在尝试向代码中添加分隔符。我让 RecylcerView 按预期工作,但 LinearLayoutManager 无法解析 getOrientation() 函数。

private RecyclerView mRecyclerView;
private RecyclerView.Adapter mAdapter;
private RecyclerView.LayoutManager mLayoutManager;

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
    View root = (View) inflater.inflate(R.layout.fragment_settings, null);
    getActivity().setTitle("Settings");

    mRecyclerView = (RecyclerView) root.findViewById(R.id.recycler_view_settings);

    mRecyclerView.setHasFixedSize(true);

    mLayoutManager = new LinearLayoutManager(getContext());
    mRecyclerView.setLayoutManager(mLayoutManager);
    mAdapter = new SettingsAdapter(getResources().getStringArray(R.array.setting_list));
    mRecyclerView.setAdapter(mAdapter);
    DividerItemDecoration dividerItemDecoration = new DividerItemDecoration(mRecyclerView.getContext(), mLayoutManager.getOrientation());
    mRecyclerView.addItemDecoration(dividerItemDecoration);
    return root;
}

我在创建分隔线时遇到了同样的问题。 你可以根据你的 RecyclerView 的方向自己简单地设置方向,LinearLayoutManager.VERTICALLinearLayoutManager.HORIZONTAL。它对我有用。

改变

private RecyclerView.LayoutManager mLayoutManager;

private LinearLayoutManager mLayoutManager;

您可以在 XML 文件的 CardView 中使用下面的代码 不在 recyclerView。

android:layout_marginTop="8dp
