过渡到谷歌地图片段导致“错误膨胀类片段”

我加载WebView到片段作为子片段。使用按钮，然后我使用TransitionManager转换到Google Map。地图加载。然后我点击另一个按钮转换回WebView。 WebView显示。但是，当我点击按钮转换回地图，我得到一个“错误膨胀类片段”。过渡到谷歌地图片段导致“错误膨胀类片段”

出于某种原因，TransitionManager无法再次膨胀场景。我重复使用了包含Google Map的相同场景。我甚至尝试用以下方法重新初始化场景：

Scene.getSceneForLayout(sceneRoot, R.layout.activity_maps, context);

但它没有帮助。当Google地图从片段中显示出来后，Google地图是否有重新初始化的问题？

UPDATE：我想我可能已经找到了解决方案（需要尝试一下与过渡）： android maps v2 crashes when reopened in fragment

回答：

对我来说，我只需要使用这个代码片段，我用的时候导航抽屉。我希望它能起作用！

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/mainl" 
    android:layout_width="match_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" > 
</RelativeLayout>

MainActivity

public class MainActivity extends FragmentActivity { 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     FragmentTransaction mTransaction = getSupportFragmentManager().beginTransaction(); 
     SupportMapFragment mFRaFragment = new MapFragmentD(); 
     Bundle args = new Bundle(); 
     args.putDouble("lat", 30.375321); 
     args.putDouble("lng", 69.345115); 
     mFRaFragment.setArguments(args); 
     mTransaction.add(R.id.mainl, mFRaFragment); 
     mTransaction.commit(); 
     try { 
      MapsInitializer.initialize(getApplicationContext()); 
     } catch (GooglePlayServicesNotAvailableException e) { 
      e.printStackTrace(); 
     } 
    } 
}

MapFragmentD

public class MapFragmentD extends SupportMapFragment { 
    GoogleMap mapView; 
    private static LatLng position ; 
// ArrayList<Map> mapclass; 
    @Override 
    public void onCreate(Bundle arg0) { 
     super.onCreate(arg0); 
    } 
    @Override 
    public View onCreateView(LayoutInflater mInflater, ViewGroup arg1, 
      Bundle arg2) { 
     return super.onCreateView(mInflater, arg1, arg2); 
    } 
    @Override 
    public void onInflate(Activity arg0, AttributeSet arg1, Bundle arg2) { 
     super.onInflate(arg0, arg1, arg2); 
    } 
    @SuppressWarnings("unchecked") 
    @Override 
    public void onActivityCreated(Bundle savedInstanceState) { 
     super.onActivityCreated(savedInstanceState); 
//  mapclass = (ArrayList<Map>)getArguments().getSerializable("Map"); 
     mapView = getMap(); 
     mapView.setMapType(GoogleMap.MAP_TYPE_NORMAL); 
//  for(int i = 0; i < mapclass.size(); i++) 
//  { 
      position = new LatLng(getArguments().getDouble("lat"), getArguments().getDouble("lng")); 
      MarkerOptions markerOptions = new MarkerOptions(); 
      markerOptions.draggable(true); 
      markerOptions.position(position); 
      markerOptions.title("test"); 
//   markerOptions.snippet(mapclass.get(i).getSpeciality()); 
      markerOptions.icon(BitmapDescriptorFactory.defaultMarker()); 
      mapView.addMarker(markerOptions); 
//  } 
     CameraPosition cameraPosition = new CameraPosition.Builder() 
     .target(position) 
     .zoom(7)     
     .bearing(90) 
     .tilt(30)  
     .build();  
     mapView.animateCamera(CameraUpdateFactory.newCameraPosition(
       cameraPosition)); 
    } 
}
