Question

我将一个WebView作为子片段加载到片段中。然后使用按钮，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时，我得到一个＆＃34;错误的类膨胀类片段＆＃34;。

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

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

但它没有帮助。谷歌地图在从片段中显示后被破坏后是否有重新初始化的问题？

更新我想我可能已经找到了解决方案（需要尝试使用转换）： android maps v2 crashes when reopened in fragment

Answer 1

在我的情况下，当我使用导航抽屉时，我只需要使用带有片段的代码。我希望它有效！

<?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));



    }
}
