Android多片段管理

我在FragmentTabHost中有两个片段，名为“List”和“Map” Map调用SupportMapFragment。Android多片段管理

我的应用程序在列表中启动，我切换到地图并切换回列表=一切都很好：D 但是，当我切换回地图应用程序崩溃，因为我重复了地图ID。

我的状况是：如果您已经创建了视图，请不要执行任何操作。它不会崩溃，但它不显示：/

我该怎么办？

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" 
     />

您正在膨胀的布局引用SupportMapFrafment，但要扩展片段。你可以做的只是扩展SupportMapFragment，不要覆盖任何方法或定义一个静态片段在地图标签

我希望我可以但我不能扩展SupportMapFragment。因为我的tabhost正在等待扩展Fragment：/ – nsvir

好吧，你是对的。我不知道我做了什么，但知道我可以使用SupportMapFragment而不是Fragment。谢谢！ – nsvir
