Did you forget to call 'public void setup(LocalActivityManager activityGroup)解决

在使用TabHost时有时出现Did you forget to call 'public void setup(LocalActivityManager activityGroup)，主要是没有继承ActivityGroup和获得ActivityManager。

错误内容描述

E/AndroidRuntime(20559): Caused by: java.lang.IllegalStateException: Did you forget to call 'public void setup(LocalActivityManager activityGroup)'?

解决方法

    public class TabDesignActivity extends ActivityGroup{  
      
        @Override  
        protected void onCreate(Bundle savedInstanceState) {  
            // TODO Auto-generated method stub  
            super.onCreate(savedInstanceState);  
            setContentView(R.layout.tab_main);  
              
            mTabHost = (TabHost) findViewById(R.id.tabhost);  
            mTabHost.setup();  
            mTabHost.setup(this.getLocalActivityManager());       
    }
