title: How to create a overlay layout upon a listview
body: <p>I have a listview that will be filled with <code>AsyncTask</code> and at the bottom edge of the app I need to show a fixed overlay layout like this:</p>
  
  <p><img src="https://i.stack.imgur.com/483hh.png" alt="enter image description here"></p>
  
  <p>But I can't figure it out how I can do this in xml?
  This is my present layout.xml:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="vertical"&gt;
  
      &lt;ListView
          android:id="@+id/list"
          android:layout_width="match_parent"
          android:layout_height="wrap_content" /&gt;
  
     &lt;!-- Probably I need to do something here  --&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
