  <pre><code>    TabSpec spec = tabHost.newTabSpec("home").setIndicator("Home").setContent(R.id.LinearLayout_home);
      tabHost.addTab(spec);
  </code></pre>
  
  <p>main.xml:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;  
  </code></pre>
  
  <p></p>
  
  <pre><code>&lt;LinearLayout android:id="@+id/LinearLayout_root" 
  android:layout_width="wrap_content" 
  android:layout_height="wrap_content"&gt;
  
      &lt;TabWidget android:id="@android:id/tabs" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content"&gt;
      &lt;/TabWidget&gt;
  
      &lt;FrameLayout android:id="@android:id/tabcontent" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent"&gt;
          &lt;include layout="@layout/home"/&gt;
      &lt;/FrameLayout&gt;      
  
  &lt;/LinearLayout&gt;
  </code></pre>
