     package org.shuxiang.tabhostsample;  

     import android.os.Bundle;
     import android.app.ActivityGroup;
     import android.content.Intent;
     import android.widget.TabHost;  

     public class MainActivity extends ActivityGroup 
     {
         private String tabHost1 = "A";
         private String tabHost2 = "B";
         private String tabHost3 = "C";
         private TabHost tabHost;  

         @Override
         public void onCreate(Bundle savedInstanceState) {
             super.onCreate(savedInstanceState);
             setContentView(R.layout.tabhost);  

             tabHost = (TabHost) findViewById(android.R.id.tabhost);

             tabHost.setup(getLocalActivityManager());  

             tabHost.setCurrentTab(0);
             tabHost.addTab(tabHost.newTabSpec(tabHost1)
             .setIndicator(tabHost1).
             setContent(new Intent(MainActivity.this, Tab1.class)));
             tabHost.addTab(tabHost.newTabSpec(tabHost2)
             .setIndicator(tabHost2)
             .setContent(new Intent(MainActivity.this, Tab2.class)));
