       &lt;/FrameLayout&gt;
  &lt;/LinearLayout&gt;
  &lt;/TabHost&gt;
  </code></pre>
  
  <p>and the activity code is </p>
  
  <pre><code>public class TabTestActivity extends Activity {
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);
      Resources res = getResources();
  
      TabHost tabs=(TabHost)findViewById(R.id.tabhost);
      tabs.setup();
  
      TabHost.TabSpec spec=tabs.newTabSpec("mitab1");
      spec.setContent(R.id.tab1);
      spec.setIndicator("sss",
              res.getDrawable(android.R.drawable.ic_btn_speak_now));
      tabs.addTab(spec);
  
      spec=tabs.newTabSpec("mitab2");
      spec.setContent(R.id.tab2);
      spec.setIndicator("TAB2",
              res.getDrawable(android.R.drawable.ic_dialog_map));
      tabs.addTab(spec);
  
  
  
      tabs.setCurrentTab(0);
  }
  </code></pre>
  
  <p>as you can see is very simple. But when I write <code>spec.setIndicator("",
                  res.getDrawable(android.R.drawable.ic_dialog_map));</code>
  I can see the icon, bu when I write <code>spec.setIndicator("TAB2",
                  res.getDrawable(android.R.drawable.ic_dialog_map));</code>
  I can only see TAB2, but no both of them.</p>
  
  <p>It seems that there are no enougth space to show both. So I've tried to get increase the tab height with this </p>
  
  <pre><code>tabs.getTabWidget().getChildAt(1).getLayoutParams().height = 150; 
  </code></pre>
  
  <p>but not seems to work.</p>
