Google maps 第二次打开片段时，片段内部的MapFragment未正确加载

我在片段中有一个mapFragment以及其他视图，当我第一次打开片段时，它工作正常，但是重新打开片段会导致一个空白（白色）屏幕

有人有同样的问题吗？或者任何人都知道如何解决这个问题。。好心帮忙

public class CostEstimationFragment extends Fragment implements OnMapReadyCallback{
private GoogleMap mMap;
MapFragment mapFragment;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
if (rootView != null) {
        ViewGroup parent = (ViewGroup) rootView.getParent();
        if (parent != null)
            parent.removeView(rootView);
    }
    try {
        if(savedInstanceState==null){
        rootView = inflater.inflate(R.layout.abc_layout, container,
                false);
        }

    } catch (InflateException e) {
        e.printStackTrace();

    }
    if(mMap==null)
    mMap = getMapFragment().getMap();
    mMap.clear();

    }

相应类abc_layout.XML的XML

<ScrollView>
<RelativeLayout>
<ListView/>

<LinearLayout
android:id="@+id/mapviewLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="50dp"
android:orientation="vertical" 
android:layout_below="@+id/estimateLayout"
android:padding="10dp"
android:background="@color/white"
android:elevation="2dp">


  <fragment
    android:id="@+id/map"
    class="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="300dp"/> 



 </LinearLayout>

 <RelativeLayout/>
 <ScrollView/>

更新-2 增加

我需要跟踪打开的所有其他片段，以便正确导航应用程序，所以我只是更改了ft.replace（R.id.frame\u container，fragment）对于此片段

现在在LogCat中获得以下错误

在片段中实现OnMapReadyCallback接口，然后像下面那样编辑代码

if(mMap==null){
  getMapFragment().getMapAsync(this);
  //remove mMap.clear();
 }
@Override
protected void onStart() {
    super.onStart();
    if(mMap==null){
      getMapFragment().getMapAsync(this);

   }
}
@Override
public void onMapReady(GoogleMap map) {
    mMap=map;
}

并更改此行：

ft.add(R.id.frame_container, fragment);

到

我是这样做的：

始终删除

onDestroyView（）

上的MapFragment以防止

充气异常

onCreateView

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState){
  if (view != null) {
       ViewGroup parent = (ViewGroup) view.getParent();
        if (parent != null)
             parent.removeView(view);
        }
        try
        {
            view = inflater.inflate(R.layout.fragment_map_layout,null);
            MapFragment mapFragment = (MapFragment) getActivity().getFragmentManager()
                    .findFragmentById(R.id.map);
            mapFragment.getMapAsync(this);
        }catch (InflateException e) {
        /* map is already there, just return view as it is */
        }
    return view;
}

onDestroyView

@Override
public void onDestroyView() {
  super.onDestroyView();
        MapFragment mapFragment = (MapFragment) getActivity().getFragmentManager()
                .findFragmentById(R.id.map);

if (mapFragment != null){
     getActivity().getFragmentManager().beginTransaction().remove(mapFragment).commit();
    }
}

希望这能对您有所帮助。

请提供fragment classI的源代码。我已经编辑了这个问题，并添加了我的类fragment和xml中所需的部分。请尝试我的答案，让我知道在传递getMapAsync（）方法getMapAsync（OnMapReadyCallback）时，我应该在getMapAsync（）内传递哪个参数在类型中，MapFragment不适用于参数（Activity）“还提供您调用此片段时的代码片段我的意思是activityType不匹配：无法从void转换为GoogleMap请将“add”替换为“replace”，正如我在五月编辑回答中所说，将“add”替换为“replace”，仍然没有运气，更新了我问题中的日志更新-2将您在瓦利德的项目发送给我_sarwar@hotmail.com

ft.replace(R.id.frame_container, fragment);

  if (view != null) {
       ViewGroup parent = (ViewGroup) view.getParent();
        if (parent != null)

        }
