LinearLayoutManager无法解析getOrientation()

Question

我在片段中实现了一个RecyclerView，并且我正在尝试向代码中添加分隔符。我让RecylcerView正常工作，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;
}

Answer 1

变化

private RecyclerView.LayoutManager mLayoutManager;

至

private LinearLayoutManager mLayoutManager;

Answer 2

当我创建一个分割器时，我也遇到了同样的问题。您可以简单地根据您的RecyclerView的方向自己设置方向，LinearLayoutManager.VERTICAL或LinearLayoutManager.HORIZONTAL。这对我很管用。

Answer 3

你可以在XML文件中的CardView中使用下面的代码，而不是在recyclerView中。

android:layout_marginTop="8dp
