我正在使用Tabbed活动，在第一个片段中我正在使用地图片段。它工作正常，但问题是如果我在此活动中的其他片段之间进行更改，则整个活动崩溃。删除地图片段后，代码运行良好。但我想在片段中放置一个地图，所以请帮助。这是我的地图片段的xml代码
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="350dp"
android:layout_height="200dp"
android:layout_marginTop="20dp"
android:id="@+id/map"
android:layout_below="@+id/textView6"
android:layout_alignParentLeft="true"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_alignParentStart="true"
android:layout_marginLeft="19dp"
android:layout_marginStart="19dp"
每次活动崩溃前都是错误 -

这是我的片段代码
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
mapFragment = ((SupportMapFragment) getChildFragmentManager()
.findFragmentById(R.id.map));
mapFragment.getMapAsync(this);
}
@Override
public void onDestroy() {
super.onDestroy();
if (mapFragment != null) {
//mMap = null;
mapFragment=null;
}
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
//Toast.makeText(getActivity(), lat + " " + lng, Toast.LENGTH_LONG).show();
LatLng locations = new LatLng(Util.reslatitude,Util.reslogitide);
if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
mMap.setMyLocationEnabled(true);
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(locations, 13));
mMap.addMarker(new MarkerOptions()
.title("abc")
.position(locations));
}
提前致谢

而不是在onActivityCreated初始化您的mapFragment onCreateView
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
mapFragment = ((SupportMapFragment) getChildFragmentManager()
.findFragmentById(R.id.map));
mapFragment.getMapAsync(this);
}
您的onActivityCreated应该是
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
添加以下代码，让我知道它是否有效
@Override
public void onPause() {
super.onPause();
getChildFragmentManager().beginTransaction()
.remove(mapFragment)
.commit();
}

而不是地图片段尝试在第一个片段中使用MapView。
