Scolling avec plusieurs RecyclerViews dans la Mise en page

J'ai été en mesure de résoudre le problème en mettant le tout à l'intérieur ScrollView et puis réglage de la hauteur de la verticale RecyclerView manuellement ou par programmation.

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/scrollView">

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

            <EditText
                android:id="@+id/search"
                android:layout_width="fill_parent"
                android:layout_height="50dp"
                android:hint="Search Dramas"
                android:textSize="16sp"
                android:paddingLeft="10dp"
                android:gravity="center"
                android:textColor="@color/dark_grey"
                android:textColorHint="@color/dark_grey"
                android:background="@drawable/border_bottom"/>


            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@drawable/border_bottom_background_black"
                android:textColor="@color/white"
                android:padding="10dp"
                android:text="Most Watched"/>

            <!-- A RecyclerView to display horizontal list -->
            <android.support.v7.widget.RecyclerView
                android:id="@+id/featured"
                android:scrollbars="none"
                android:layout_width="fill_parent"
                android:layout_height="240dp"
                android:paddingLeft="0dp"
                android:paddingRight="15dp"
                android:paddingTop="15dp"
                android:paddingBottom="25dp"
                android:background="@color/black"/>

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@drawable/border_bottom_backgroundless"
                android:textColor="@color/dark_grey"
                android:padding="10dp"
                android:text="All Dramas"/>

            <!-- A RecyclerView to display list -->
            <android.support.v7.widget.RecyclerView
                android:id="@+id/pick_item"
                android:paddingBottom="20dp"
                android:scrollbars="vertical"
                android:layout_width="fill_parent"
                android:layout_height="match_parent"
                android:minHeight="840dp"/>


    </LinearLayout>
</ScrollView>

Réglage RecyclerView de la hauteur de base du programme:

LinearLayout.LayoutParams params = new     
     LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, 
     ViewGroup.LayoutParams.WRAP_CONTENT);
//calculate height of RecyclerView based on child count
params.height=1150;
//set height of RecyclerView
recyclerView.setLayoutParams(params);
