作爲片段標籤之一的片段中的Map v2的問題

Question

有3個選項卡的應用程序，我已經使用選項卡主機和片段活動。我在第一個選項卡中有一個地圖，當我第一次啓動它時工作正常，當我切換選項卡並返回我的應用程序崩潰並給我一個錯誤膨脹類異常時，會顯示地圖。

這裏是我的標籤更改代碼listerner

getActivity().getSupportFragmentManager().beginTransaction().replace(placeholder, new MapView(), "Maps").commit(); 

這裏是我的片段級代碼

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

     view = inflater.inflate(R.layout.map_view, container, false); 

    return view; 
} 

這裏是我的logcat的

Answer 1

這是回答by Vidar here：Duplicate ID, tag null, or parent id with another fragment for com.google.android.gms.maps.MapFragment

他的解決方案是：

if (view != null) { 
    ViewGroup parent = (ViewGroup) view.getParent(); 
    if (parent != null) 
     parent.removeView(view); 
} 
try { 
    view = inflater.inflate(R.layout.map, container, false); 
} catch (InflateException e) { 
    /* map is already there, just return view as it is */ 
} 
return view;
