title: Fill Android Tab with custom pic and/or colour
body: <p>Hey all I've created Google's exmaple of a <a href="http://developer.android.com/resources/tutorials/views/hello-tabwidget.html" rel="nofollow">tab layout</a></p>
  
  <p>HelloTabWidget.java:</p>
  
  <pre><code>public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  
  Resources res = getResources(); // Resource object to get Drawables
  TabHost tabHost = getTabHost();  // The activity TabHost
  TabHost.TabSpec spec;  // Resusable TabSpec for each tab
  Intent intent;  // Reusable Intent for each tab
  
  // Create an Intent to launch an Activity for the tab (to be reused)
  intent = new Intent().setClass(this, ArtistsActivity.class);
  
  // Initialize a TabSpec for each tab and add it to the TabHost
  spec = tabHost.newTabSpec("artists").setIndicator("Artists",
                    res.getDrawable(R.drawable.ic_tab_artists))
                .setContent(intent);
  tabHost.addTab(spec);
  
  // Do the same for the other tabs
  intent = new Intent().setClass(this, AlbumsActivity.class);
  spec = tabHost.newTabSpec("albums").setIndicator("Albums",
                    res.getDrawable(R.drawable.ic_tab_albums))
                .setContent(intent);
  tabHost.addTab(spec);
  
  intent = new Intent().setClass(this, SongsActivity.class);
  spec = tabHost.newTabSpec("songs").setIndicator("Songs",
                    res.getDrawable(R.drawable.ic_tab_songs))
                .setContent(intent);
  tabHost.addTab(spec);
  
  tabHost.setCurrentTab(2);
  </code></pre>
  
  <p>}</p>
  
  <p>I know how to create my own icon to use instead of their grey and white microphone, but I can't figure out how to make my custom icon fill the entire tab.  When the tab is selected it's a light grey with my pic in the middle and when not selected its a dark grey with my pic in the middle.  I prefer to have my own pic fill the entire tab, and for more knowledgeable; my own choice in color to fill the tab.</p>
