title: AdView attached to bottom doesn't let me see last item in Recyclerview
body: <p>I have a <code>RelativeLayout</code> in wich I have a <code>RecyclerView</code> and a <code>LinearLayout</code> with an <code>AdView</code> inside. The <code>RecyclerView</code> has many items and when I was unable to show them in the screen I just had to scroll down to see them, but now that I added the <code>LinearLayout</code> attached to the bottom of the screen with the <code>AdView</code> inside I scroll down and I'm not able to see the last item of the <code>RecyclerView</code>. I'm attaching the <code>LinearLayout</code> to the bottom but it seems that It's above the <code>RecyclerView</code> and I want the <code>RecyclerView</code> to show items in the screen but not behind the <code>LinearLayout</code>. Is it possible?</p>
  
  <p>Here's my XML for the Layout:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  xmlns:ads="http://schemas.android.com/apk/res-auto"&gt;
  
  &lt;android.support.v7.widget.RecyclerView
      android:id="@+id/rvGeneric"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:scrollbars="vertical"&gt;
  &lt;/android.support.v7.widget.RecyclerView&gt;
  
  &lt;LinearLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_alignParentBottom="true"
      android:gravity="center"&gt;
  
      &lt;com.google.android.gms.ads.AdView
          android:id="@+id/adViewBaseRefresh"
          android:layout_width="fill_parent"
          android:layout_height="53dp"
          ads:adSize="BANNER"
          ads:adUnitId="@string/banner_ad_unit_id"
          android:layout_marginBottom="3dp"&gt;
      &lt;/com.google.android.gms.ads.AdView&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p></p>
