求助，Activities can't be added until the containing group has been created

在一个Activity里面放一个抽屉，抽屉里面放个Tab，弄了好久没有成功

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

	    tabHost.setup( new ActivityGroup().getLocalActivityManager ()); 



	    if (tabHost==null)Log.i("JSY", "NULL");

	    else Log.i("JSY", "NOTNULL");

	   // 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, MyChanceList.class); 

     

        // Initialize a TabSpec for each tab and add it to the TabHost 

        spec = tabHost.newTabSpec(res.getString(R.string.str_forecast)).setIndicator(res.getString(R.string.str_forecast), 

                          res.getDrawable(R.drawable.icon)) 

                      .setContent(intent); 

        tabHost.addTab(spec); 

     

        // Do the same for the other tabs 

        intent = new Intent().setClass(this, OtherChanceList.class); 

        spec = tabHost.newTabSpec(res.getString(R.string.str_history)).setIndicator(res.getString(R.string.str_history), 

                          res.getDrawable(R.drawable.icon)) 

                      .setContent(intent); 

        tabHost.addTab(spec); 

        tabHost.setCurrentTab(0);

错误信息如下
