Tabhost內片段不工作

Question

//HappChat.java

public class HappChat extends Fragment { 

TabHost tabhost; 

@Override 
public View onCreateView(final LayoutInflater inflater, final ViewGroup container, 
     Bundle savedInstanceState) { 

    View rootView = inflater.inflate(R.layout.chat_header, container, false); 

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

    tabhost.setup(); 

    TabSpec ts = tabhost.newTabSpec("Tab 1"); 
    ts.setIndicator("", getResources().getDrawable(R.drawable.tab_user)); 
    ts.setContent(new Intent(getActivity(), ChatFirstTab.class)); 
    tabhost.addTab(ts); 

    TabSpec ts1 = tabhost.newTabSpec("Tab 2"); 
    ts1.setIndicator("", getResources().getDrawable(R.drawable.tab_chat)); 
    ts1.setContent(new Intent(getActivity(), ChatSecondTab.class)); 
    tabhost.addTab(ts1); 

    for(int i=0;i<tabhost.getTabWidget().getChildCount();i++) 
    { 
     tabhost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#E8E8E8")); 
    } 
    tabhost.getTabWidget().setCurrentTab(0); 
    tabhost.getTabWidget().getChildAt(0).setBackgroundColor(Color.parseColor("#FFFFFF")); 

    tabhost.setOnTabChangedListener(new OnTabChangeListener() { 

     @Override 
     public void onTabChanged(String tabId) { 
      // TODO Auto-generated method stub 
      for(int i=0;i<tabhost.getTabWidget().getChildCount();i++) 
      { 
       tabhost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#E8E8E8")); 
      } 

      tabhost.getTabWidget().getChildAt(tabhost.getCurrentTab()).setBackgroundColor(Color.parseColor("#FFFFFF")); 
     } 
    }); 

    return rootView; 
    } 
} 

//ChatFirstTab.java

public class ChatFirstTab extends Fragment { 

@Override 
public View onCreateView(final LayoutInflater inflater, final ViewGroup container, 
     Bundle savedInstanceState) { 

    View rootView = inflater.inflate(R.layout.chat_first, container, false); 

    return rootView; 
    } 
} 

//ChatSecondTab.java

public class ChatSecondTab extends Fragment { 

@Override 
public View onCreateView(final LayoutInflater inflater, final ViewGroup container, 
     Bundle savedInstanceState) { 

    View rootView = inflater.inflate(R.layout.chat_first, container, false); 

    return rootView; 
    } 
} 

我的問題是，運行時上面的代碼顯示了下面描述的錯誤。

06-23 04:32:00.658: E/AndroidRuntime(12802): java.lang.IllegalStateException: Did you forget to call 'public void setup(LocalActivityManager activityGroup)'?

etc... 

如何解決這個錯誤。我嘗試了很多，並提到更多的鏈接，但沒有成功。有沒有解決這個錯誤的方法。

任何幫助，將不勝感激。
