Android多片段管理

我在FragmentTabHost中有兩個片段，名爲「List」和「Map」 Map調用SupportMapFragment。Android多片段管理

我的應用程序在列表中啓動，我切換到地圖並切換回列表=一切都很好：D 但是，當我切換回地圖應用程序崩潰，因爲我重複了地圖ID。

我的狀況是：如果您已經創建了視圖，請不要執行任何操作。它不會崩潰，但它不顯示：/

我該怎麼辦？

MapFragment.java

public class MapFragment extends Fragment{ 

    private View view; 

    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     if (view != null){ 
      return null; 
     } 
     view = inflater.inflate(R.layout.map, null, false); 
     return view; 
    } 
}

map.xml

<?xml version="1.0" encoding="utf-8"?> 
<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
      android:id="@+id/map" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
     class="com.google.android.gms.maps.SupportMapFragment" 
     />

如果你有崩潰，從logcat發佈stacktrace。 – Karakuri

您正在膨脹的佈局引用SupportMapFrafment，但要擴展片段。你可以做的只是擴展SupportMapFragment，不要覆蓋任何方法或定義一個靜態片段在地圖標籤

我希望我可以但我不能擴展SupportMapFragment。因爲我的tabhost正在等待擴展Fragment：/ – nsvir

好吧，你是對的。我不知道我做了什麼，但知道我可以使用SupportMapFragment而不是Fragment。謝謝！ – nsvir
