Java 谷歌地图API地面覆盖不'；在应用程序中无法工作

对于我正在开发的应用程序，我想制作一个图像覆盖。在iOS上，我使用了GoogleMapsAPI，这非常有效。但在相同的设置、配置和API下，它无法在Android上运行。这就是我得到的结果：

这显然不是我希望看到的，因为我的图像是正方形的，根据坐标应该看起来更低

我使用以下代码：

    public class MapFragment extends Fragment implements OnMapReadyCallback {

    LatLng lastValidTarget;

    public MapFragment() {
        // Required empty public constructor
    }

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        inflater.inflate(R.menu.filler_menu, menu);
        super.onCreateOptionsMenu(menu, inflater);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == R.id.action_filler) {
            System.out.println("filler");
            return true;
        }

        return false;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        setHasOptionsMenu(true);

        View fragmentView = inflater.inflate(R.layout.fragment_map, container, false);

        return fragmentView;
    }

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        com.google.android.gms.maps.SupportMapFragment fragment = (com.google.android.gms.maps.SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.map);
        fragment.getMapAsync(this);
    }

    @Override
    public void onMapReady(final GoogleMap googleMap) {
        LatLng target = new LatLng(52.051361, 4.522754);
        this.lastValidTarget = target;

        CameraPosition cameraPosition = new CameraPosition.Builder()
                .target(target)            // Sets the center of the map to Mountain View
                .zoom(18)                  // Sets the zoom
                .bearing(38)               // Sets the orientation of the camera to east
                .tilt(0)                   // Sets the tilt of the camera to 30 degrees
                .build();                  // Creates a CameraPosition from the builder
        googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));

        //googleMap.setMapType(GoogleMap.MAP_TYPE_NONE);
        googleMap.setMyLocationEnabled(true);

        LatLngBounds bounds = new LatLngBounds(
                new LatLng(52.046518, 4.529650),       // South west corner
                new LatLng(52.056125, 4.516046));      // North east corner

        GroundOverlay overlay = googleMap.addGroundOverlay(new GroundOverlayOptions()
                .image(BitmapDescriptorFactory.fromResource(R.drawable.tester))
                .positionFromBounds(bounds)
                .bearing(0)
                .transparency(0.3f));
    }
}

以及以下内容（fragment_map.xml）

我正在使用的代码中是否有错误，或者我是否使用了错误的代码？提前感谢。

问题是您定义的LatLngBounds

不正确。如文档中所述，
LatLngBounds
的构造器预期为西南和东北，您正在交换坐标（东南和西北）

要解决此问题，请将yout
LatLngBounds
更改为

LatLngBounds bounds = new LatLngBounds(new LatLng(52.046518, 4.516046), new LatLng(52.056125, 4.529650));

或者更好地使用
LatLngBounds.Builder
来避免错误：

LatLngBounds bounds = LatLngBounds.builder()
    .include(new LatLng(52.046518, 4.529650))
    .include(new LatLng(52.056125, 4.516046))
    .build();

LatLngBounds bounds = LatLngBounds.builder()
    .include(new LatLng(52.046518, 4.529650))
    .include(new LatLng(52.056125, 4.516046))
    .build();
