Android的碎片

Question

內谷歌地圖V2我有以下代碼：

public class Tab_Map extends SupportMapFragment { 

View view; 
SupportMapFragment gmap; 
GoogleMap map; 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    view = inflater.inflate(R.layout.tab_map, container, false); 

    map = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.fragment1)) 
       .getMap(); 
    return view; 
} 

當我運行我的應用程序，並嘗試加載地圖選項卡我收到以下錯誤：

我可以找不到解決這個問題的辦法，我所要做的就是在地圖內部放置一張地圖。

有人可以幫忙。

確定這樣的解決辦法是添加以下行：

super.onCreateView(inflater, container, savedInstanceState);
