Recylerview not visible inside scrollview or nestedScrollview

Question

I want to place a RecylerView inside NestedScrollView as below

activity_service_menu.xml

<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="HELLO" />

        <android.support.v7.widget.RecyclerView
            android:id="@+id/rv"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="8dp" />
    </LinearLayout>
</android.support.v4.widget.NestedScrollView>

ServiceMenuActivity.java

public class ServiceMenuTActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_service_menu_t);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        RecyclerView rv = (RecyclerView) findViewById(R.id.rv);
        rv.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
        rv.setHasFixedSize(true);
        rv.setAdapter(new RvAdapter());
    }

    private static class RvAdapter extends RecyclerView.Adapter<RvAdapter.RvHolder> {

        @Override
        public RvHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            View serviceMenuItemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item_service_menu, parent, false);
            return new RvHolder(serviceMenuItemView);
        }

        @Override
        public void onBindViewHolder(RvHolder holder, int position) {

        }

        @Override
        public int getItemCount() {
            return 100;
        }

        public static class RvHolder extends RecyclerView.ViewHolder {

            public RvHolder(View itemView) {
                super(itemView);
            }
        }
    }

}

I have put the linearLayout inside scrollView and nestedScrollView. But the RecyclerView is not visible. If I replace ScrollView with FrameLayout or any other layout, then RecyclerView is visible.

I want to use nestedScrollView and scroll the total layout when recyclerView is scrolled. Unfortunately recyclerView is not even visible.

do you really need `LinearLayout` as parent of `RecyclerView` inside `NestedScrollView` ? — Vipul Asri, Oct 14 '15 at 08:25
No. As the ScrollView accepts only 1 child, I have put LinearLayout as wrapper. I need RecyclerView below the TextView and when RecyclerView is scrolled, the whole view should scroll. — Narendra, Oct 14 '15 at 14:08
can you describe basically what type of behavior you want? like Collapsing Toolbar or anything else. — Vipul Asri, Oct 15 '15 at 05:55
Not sure it would work but try setting a fix height to recyclerView instead of wrap_content — Apurva, Oct 15 '15 at 09:01
@Apurva: Fixing the height of recyclerView worked. For people who come to this question.. more info on using nestedScrollView inside scrollView: [link](http://stackoverflow.com/questions/31000081/how-to-use-recyclerview-inside-nestedscrollview) — Narendra, Oct 15 '15 at 10:17

Follow this sample will get idea where you done mistake. Main Line is : android:fillViewport="true".

<android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fillViewport="true"
        android:theme="@style/ThemeOverlay.AppCompat.Light"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:paddingTop="24dp">


        <android.support.v7.widget.CardView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="16dp">


        <com.app.view.CustomRecyclerView
            android:id="@+id/recycler_movie_suggestion"
            android:layout_width="match_parent"
            android:layout_height="170dp"
            android:fillViewport="true"
            app:layout_behavior="@string/appbar_scrolling_view_behavior" />

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

    </LinearLayout>

    </android.support.v4.widget.NestedScrollView>

You sir are amazing. It seems setting fillViewport="true" on the NestedScrollView did the trick. Thank you! — Pkmmte, Oct 29 '15 at 00:16
This is the only one solution that worked for me, i tried each one from related questions but no one worked. — UrielUVD, Feb 17 '16 at 23:19
