title: Expandable recycler view and a textview below issue
body: <p>I'm trying to implement a 2 expandable recyclerview with 2 headings.So my view has 
  1. 
  2. 
  3. 
  4. 
  Since my recyclerview is expandable, and when I expand the 1st recyclerview , it goes inside my 2nd textview.
  ie.there is a separate scroll for my recycler view.</p>
  
  <p>I want the 2nd textview and recyclerview to move down when expanding the 1st recyclerview.</p>
  
  <p>activity.xml</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:fillViewport="true"&gt;
  &lt;LinearLayout
      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"
      android:orientation="vertical"
      android:layout_marginBottom="10dp"
      tools:context=".ListActivity"&gt;
  
      &lt;TextView
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:textStyle="bold"
          android:textSize="22sp"
          android:text="Weightage: 40%"/&gt;
  &lt;LinearLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"&gt;
      &lt;android.support.v7.widget.RecyclerView
          android:id="@+id/recview"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:background="#fafafa" /&gt;
  &lt;/LinearLayout&gt;
      &lt;TextView
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:textStyle="bold"
          android:textSize="22sp"
          android:layout_marginBottom="10dp"
          android:text="Weightage: 60%"/&gt;
      &lt;android.support.v7.widget.RecyclerView
          android:id="@+id/recview2"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:background="#fafafa" /&gt;
  &lt;/LinearLayout&gt;
  &lt;/ScrollView&gt;

  <p>the same happens with the second recyclerview. On expanding the second recycler view, recyclerview items have a separate scroll and the text above stays at a place.The overall scroll doesn't work.</p>
