title: Why recyclerView is not visible under scrollView?
body: <p>I want a layout in which I need recyclerView in between two views and for scrolling all, i need scrollView. I have created a sample program in which i have used below xml: </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:fillViewport="true"
  tools:context="com.example.vatishs.recyclerviewunderscrollview.MainActivity"&gt;
  
  &lt;LinearLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="vertical"
      android:paddingLeft="@dimen/activity_horizontal_margin"
      android:paddingRight="@dimen/activity_horizontal_margin"&gt;
  
  
      &lt;EditText
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:gravity="bottom|start"
          android:hint="Hint" /&gt;
  
      &lt;android.support.v7.widget.RecyclerView
          android:id="@+id/mRecycler"
          android:layout_width="match_parent"
          android:layout_height="wrap_content" /&gt;
  
      &lt;EditText
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:gravity="bottom|start"
          android:hint="Hint" /&gt;
  &lt;/LinearLayout&gt;
  &lt;/ScrollView&gt;
  </code></pre>
  
  <p>Now, I don't understand why recyclerView is not visible when i run this program?</p>
  
  <p>It is visible if I am not use scrollView.</p>
