title: How to display a "Loading..." text while retrieving items for a ListView
body: <p>There are some others applications doing this, like Twitter, Facebook, or even native applications such as Android Market. When you want to display a list of items retrieved from the internet, this looks like a standard way for displaying the user some notification about action in progress. This is a white background screen with an animated spinning wheel and a "Loading..." text. </p>
  
  <p>Does somebody know how to do this?</p>
  
  <p>I've been able to do something similar with this code, but I don't like it too much yet. Still work in progress:</p>
  
  <pre><code>&lt;ListView android:id="@+id/post_list" 
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"/&gt;
  
     &lt;TextView android:id="@android:id/loading" 
         android:background="@color/white"
         android:layout_width="fill_parent"     
         android:layout_height="fill_parent" 
         android:gravity="center" android:text="Loading..." /&gt;
  </code></pre>
