import com.wicresoft.myandroid.R; 
 
import android.app.TabActivity; 
import android.os.Bundle; 
import android.util.Log; 
import android.widget.TabHost; 
import android.widget.TabHost.OnTabChangeListener; 
 
@SuppressWarnings("deprecation") 
public class mainActivity extends TabActivity { 
  private TabHost tabhost; 
  @Override 
  protected void onCreate(Bundle savedInstanceState){ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main_activity); 
    //从TabActivity上面获取放置Tab的TabHost 
    tabhost = getTabHost(); 
    tabhost.addTab(tabhost 
         //创建新标签one 
        .newTabSpec("one") 
        //设置标签标题 
        .setIndicator("红色") 
        //设置该标签的布局内容 
        .setContent(R.id.widget_layout_red)); 
    tabhost.addTab(tabhost 
        .newTabSpec("two") 
        .setIndicator("黄色")

    tabhost.addTab(tabhost 
        .newTabSpec("three") 
        .setIndicator("蓝色") 
        .setContent(R.id.widget_layout_blue)); 
    tabhost.setOnTabChangedListener(listener); 
  } 
   
  private OnTabChangeListener listener = new OnTabChangeListener(){ 
    @Override 
    public void onTabChanged(String arg0) { 
      // TODO Auto-generated method stub 
      Log.i("TabChange", arg0); 
    } 
  };
