Android - Calling RecyclerView in Fragment of Navigation Drawer

My trouble is when I want to call RecyclerView into Fragment of NavigationDrawer and items (arrays) that I call via RecyclerView not called, but when I do not put into Fragment it could be called. So Here is my code.

Here is my Fragment.java and it says error on recyclerView.setLayoutManager(layoutManager);

public class fragment_1bakso extends Fragment {

private AppCompatActivity compat;
private RecyclerView recyclerView;
private MakananAdapter adapter;
public fragment_1bakso() {
    // Required empty public constructor
}

ArrayList<Makanan> mList = new ArrayList<>();
MakananAdapter mAdapter;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    /*View v = inflater.inflate(R.layout.fragment_1bakso, container, false);
    return v;*/
    View rootview = inflater.inflate(R.layout.activity_calling, container, false);
    return rootview;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //mClass.setContentView(R.layout.activity_calling);
    //return new fragment_1bakso(R.layout.activity_calling, this);


    GridLayoutManager layoutManager = new GridLayoutManager(getActivity(), 2, GridLayoutManager.HORIZONTAL, false);
    recyclerView.setLayoutManager(layoutManager);

    mAdapter = new MakananAdapter(mList);
    recyclerView.setAdapter(mAdapter);


    fillData();
}

private void fillData() {
    Resources resources = getResources();
    String [] arJudul = resources.getStringArray(R.array.bakso);
    String [] arHarga = resources.getStringArray(R.array.bakso_price);
    String [] arDeskripsi = resources.getStringArray(R.array.bakso_desc);
    String [] arLokasi = resources.getStringArray(R.array.bakso_locations);
    String [] arDetail = resources.getStringArray(R.array.bakso_details);
    TypedArray a = resources.obtainTypedArray(R.array.bakso_pict);
    Drawable[] arFoto = new Drawable[a.length()];

    for (int i = 0; i < arFoto.length; i++)
    {
        arFoto[i] = a.getDrawable(i);
    }
    a.recycle();

    for (int i = 0; i < arJudul.length; i++)
    {
        mList.add(new Makanan(arJudul[i],arHarga[i],arFoto[i],arDeskripsi[i],arDetail[i],arLokasi[i]));
    }
    mAdapter.notifyDataSetChanged();

}}

Here is my Fragment.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="id.sch.smktelkom_mlg.learn.sideview.fragment_1bakso">

    <!-- TODO: Update blank fragment layout -->
    <include
        layout="@layout/activity_calling"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</FrameLayout>

Here is my Activity_calling.xml that used to call the item in array (RecyclerView)

    <?xml version="1.0" encoding="utf-8"?>
    <android.support.v7.widget.RecyclerView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clipToPadding="false"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:scrollbars="vertical"
    tools:context="id.sch.smktelkom_mlg.learn.sideview.activity_1bakso" />

Help me guys, thanks in advance.

You did not initialise your recyclerview which can be done as :

RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recyclerview);

And define grid layout manager as :

 GridLayoutManager gridLayoutManager = new GridLayoutManager(getContext(), 2);
    recyclerView .setHasFixedSize(true);
    recyclerView .setItemAnimator(new DefaultItemAnimator());
    recyclerView .setLayoutManager(gridLayoutManager);

And yes move your code from onCreate to onViewCreated as :

 @Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
}

Hope it helps.. happy coding :)

You haven't initialized your recyclerView.

recyclerView = (RecyclerView) view.findViewById(R.id.your_id);

Also move the code from onCreate() to onViewCreated();

final RecyclerView.LayoutManager mLayoutManager =new GridLayoutManager(getContext(), 1);
    recyclerView_drawer.setLayoutManager(mLayoutManager);
    recyclerView_drawer.setItemAnimator(new DefaultItemAnimator());
    recyclerView_drawer.setAdapter(drawerAdapter);

Hope this code will help you.you can replace frame layout with Relative Layout also,as you said in frame layout its not working.

If you need grid layout manager you can try this out

GridLayoutManager layoutManager = new GridLayoutManager(this, 1);

Or you can go for a horizontal linear layout manager like so

LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false)

Or you can go for a vertical linear layout manager like so

LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false)
