title: only icon on tabs
body: <p>I'm wondering how to suppress the label on the tabs
  I want only an icon</p>
  
  <pre><code>    intent = new Intent().setClass(this, Test.class);
      spec = tabHost.newTabSpec("test").setIndicator("test", 
                      res.getDrawable(R.drawable.ic_tab_test))
                    .setContent(intent);
      tabHost.addTab(spec);
  </code></pre>
  
  <p>I have an xml file for each tab describing the icon
  All works perfectly except I want to have ONLY the icon, not the label</p>
  
  <p>Thanx</p>
