Questions:

I dont know what’s happen?

How can solve it?

HomeFragment

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View view = inflater.inflate(R.layout.ifunpot_feed, container, false);



    recyclerView1 = (RecyclerView) view.findViewById(R.id.recy_feed);
    recyclerView2 = (RecyclerView) view.findViewById(R.id.recy_stories);

    RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getActivity());
    recyclerView1.setLayoutManager(layoutManager);

    RecyclerView.LayoutManager layoutManager1 = new LinearLayoutManager(getActivity());
    ((LinearLayoutManager) layoutManager1).setOrientation(LinearLayoutManager.HORIZONTAL);
    recyclerView2.setLayoutManager(layoutManager1);

    adapterFeed = new RecyclerViewAdapterFeed(getActivity(), feedModelArrayList);
    adapterStories = new RecyclerViewAdapterStories(getActivity(), storiesModelArrayList);

    recyclerView1.setAdapter(adapterFeed);
    recyclerView2.setAdapter(adapterStories);

    populaterecyclerview();

    populaterecyclerviewstories();


    return inflater.inflate(R.layout.fragment_home, container, false);
}

The error occurs in recyclerView1.setLayoutManager(layoutManager);

fragment_home.xml

    <RelativeLayout
        android:id="@+id/rel_lay1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recy_stories"
            android:orientation="horizontal"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

        </android.support.v7.widget.RecyclerView>

        <View
            android:id="@+id/line_1"
            android:layout_below="@id/recy_stories"
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:alpha=".2"
            android:background="@android:color/black"
            android:layout_marginTop="10dp"/>
    </RelativeLayout>

    <android.support.v7.widget.RecyclerView
        android:layout_below="@id/rel_lay1"
        android:id="@+id/recy_feed"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </android.support.v7.widget.RecyclerView>
</RelativeLayout>
