title: RecyclerView inside RecyclerView does not scroll
body: <p>Hi I have a RecyclerView which contains another RecyclerView (please see the image), the inner RecyclerView does not scroll: for example look at the 7th of September in which the last activity is not visible at all but the RecyclerView does not scroll to display it.
  Here's the outer layout: </p>
  
  <pre><code>    &lt;android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/swipeContainer"
      android:layout_width="match_parent"
      android:layout_height="0dp"
      app:layout_constraintBottom_toBottomOf="parent"
      app:layout_constraintTop_toBottomOf="@+id/square"&gt;
  
      &lt;android.support.v7.widget.RecyclerView
          android:id="@+id/reciclo"
          android:layout_width="match_parent"
          android:layout_height="match_parent" /&gt;
  
  &lt;/android.support.v4.widget.SwipeRefreshLayout&gt;
  </code></pre>
  
  <p>and the inner one: </p>
