除非您触摸mapview,否则不会加载Android MapView

我在我的android应用程序中添加了一个mapview.我在清单中使用了正确的设置,现在我遇到了问题.当我去我有地图的地方时,它只显示画布而不显示地图.如果我触摸它只开始加载.即使这样它也没有完全加载.它只加载到一定的水平.如果我继续触摸屏幕,它会不断加载.但即使这样我也无法放大或缩小,甚至无法移动地图.这有解决方案吗？我做错了什么吗？

我的守则

            MapView mapView;
            GoogleMap map;





             mapView = (MapView)view.findViewById(R.id.map);
             Bundle savedInstanceState = null;
            mapView.onCreate(savedInstanceState);

                // Gets to GoogleMap from the MapView and does initialization stuff
                map = mapView.getMap();
                map.getUiSettings().setMyLocationButtonEnabled(false);
                map.setMyLocationEnabled(true);

                MapsInitializer.initialize(activity);

                double lat;
                double lon;

                lat = Double.parseDouble(theaterDetail.getLatitude());
                lon = Double.parseDouble(theaterDetail.getLongitude());

                // Updates the location and zoom of the MapView
                map.addMarker(new MarkerOptions().position(
                        new LatLng(lat, lon)).title(theaterDetail.getAddress()));

                final LatLng THEATER_POSITION = new LatLng(lat, lon);

                CameraPosition cameraPosition = new CameraPosition.Builder()
                        .target(THEATER_POSITION) // Sets the center of the map to
                                                    // THEATER_POSITION
                        .zoom(10) // Sets the zoom
                        .bearing(360) // Sets the orientation of the camera to east
                        .tilt(30) // Sets the tilt of the camera to 30 degrees
                        .build(); // Creates a CameraPosition from the builder
                        map.animateCamera(CameraUpdateFactory
                        .newCameraPosition(cameraPosition));

解决方法:

虽然这是一个老问题,但我在这里提供了对我有用的东西.此解决方案的工作原理是它覆盖了onResume()处理程序.如果您使用的是mapView,则需要从onResume()处理程序调用mapView.onResume().例：

@Override
public void onResume() {
    mMapView.onResume();
    super.onResume();
}
