我的活动结果是错的

Question

我真的不知道如何解决这个问题，我发现很多很多的解决方案，但仍然无法正常工作。

我的问题是我的活动跳转到TabHost后，标签页浏览量变为空白，但是当我切换标签时，这是正常的。

我猜日期已经准备好，当活动第一次跳，但为什么它不显示正常？

任何帮助将非常感激..

这一点，活动，其中在跳下TabHost。

public class ListContainActivity extends FragmentActivity{ 

    public static final String tag = "COOLSMILE_DEBUG"; 
    private TabHost tabHost ;

     InitTabHost();

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

       switch (checkedId) {

         break;

      } 
     });    
    } 

    private void getIntentExtra(){ 
     Intent intent = getIntent(); 
     mString = intent.getExtras().getString("PRESIDENTS_CONTENT"); 
    } 

}

我找到了原因，那是因为Tag和setContent(R.id.contain_tab1)不是一比一relationship.I以为只是之前设置一个时间，现在我有解决的问题。
