LinearLayoutManager cannot resolve getOrientation()

Question

I have a RecyclerView implemented in a fragment and I'm trying to add dividers to the code. I have the RecylcerView working as intended, but the LinearLayoutManager cannot resolve the getOrientation() function.

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;
}

I was under the assumption that because I was able to initialize mLayoutManager as a LinearLayoutManager that I would be able to use its functions. Changing RecyclerView.LayoutManager mLayoutManager to LinearLayoutManager mLayoutManager resolved the issue. — Ryan Newquist, Jan 10 '17 at 00:05
LayoutManager does not declare a getOrientation() method, LinearLayoutManager does. — BladeCoder, Feb 19 '17 at 01:37

I got the same issue when I create a divider. You can simply put the orientation yourself, LinearLayoutManager.VERTICAL or LinearLayoutManager.HORIZONTAL, according to the orientation your RecyclerView. It works for me.

You can use code below at CardView at XML file Not at recyclerView.

android:layout_marginTop="8dp
