title: RelativeLayout zorder lollipop
body: <p>I have a little layout working correctly on API 19: 4.2.2 but can't make it work on API 21: 5.0.1.</p>
  
  <p>Here is 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" &gt;
  
      &lt;Button
          android:id="@+id/start_button"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:textStyle="bold"
          android:textSize="30sp"
          android:background="@color/start_button_bg"
          android:textColor="@color/start_button_text"
          android:text="@string/start_process"/&gt;
  
      &lt;TextView
          android:id="@+id/pro_icon"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_margin="10dp"
          android:layout_alignParentRight="true"
          android:layout_alignParentTop="true"
          android:textColor="@android:color/white"
          android:background="@drawable/pro_icon"
          android:text="PRO"
          android:gravity="center"
          android:textAppearance="?android:attr/textAppearanceMedium"/&gt;
  
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>Really simple stuff. I just want the textview to be over the Button in the relative layout. I know relative layout stacks views in the order they are added in the xml, but this seems not to be working the same on lollipop. I can't get the TextView to be rendered over the button. Any idea?</p>
  
  <p>Cheers.</p>
