android - Mapbox 'setMyLocationEnabled' 不工作

Question

我正在尝试在我的 mapbox map 中启用一个位置。 但是，行 mapboxMap.setMyLocationEnabled(true); 失败并且 Android Studio 给出“无法解析方法 setMyLocationEnabled(boolean)”。

我在我的 Gradle 中使用 MapBox 版本 6.0.1(最新):

//
compile ('com.mapbox.mapboxsdk:mapbox-android-sdk:6.0.1@aar') {  // Map BOX
    transitive=true
}

当我切换到版本 5.1.3(我在之前制作的应用程序中使用过)时，Android Studio 检测到该方法，但在运行时应用程序抛出以下异常: android.view.InflateException:二进制 XML 文件第 0 行:错误膨胀类 com.mapbox.mapboxsdk.maps.MapView

希望在这方面得到一些帮助。 相关代码如下，谢谢!

这是 Activity 中的相关代码:

mapView = (MapView) findViewById(R.id.map);
mapView.onCreate(savedInstanceState);
mapView.getMapAsync(new OnMapReadyCallback() {
        @Override
        public void onMapReady(MapboxMap mapboxMap) {
            // Set map style
            mapboxMap.setStyleUrl(Style.MAPBOX_STREETS);


            // Set the camera's starting position
             CameraPosition cameraPosition = new CameraPosition.Builder()
                    .target(new LatLng(32.1622,34.8338)) // set the camera's center position on the first coordinate of the tour
                    .zoom(14)  // set the camera's zoom level
                    .tilt(0)  // set the camera's tilt
                    .build();

            // Move the camera to that position
                mapboxMap.moveCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));

            // Set user location
            mapboxMap.setMyLocationEnabled(true);

            //Set MyLocation Button
            //userLocationFAB(DrivingActivity.get, mapboxMap);

            // Add route line
            //mapboxMap.addPolyline(getRoute());

//                // Add markers
//                ArrayList<MarkerOptions> markers = getMarkers();
//
//                for (int i=0 ; i<markers.size() ; i++) {
//                    mapboxMap.addMarker(markers.get(i));
//                }
            }
        });
    }

这是来自 XML 文件的代码:

@Hey mickey 检查这个，如何获取当前位置:

           mapFragment.getMapAsync(new OnMapReadyCallback() {
           @Override
           public void onMapReady(MapboxMap mapboxMap) {
            mapboxmap = mapboxMap;
            mapboxMap.setOnMapClickListener(DetailDirectionFragment.this);
            mapboxMap.getUiSettings().setZoomControlsEnabled(true);
            initLocationEngine();

        }
    });

@SuppressWarnings( {"MissingPermission"})
private void initLocationEngine() {
    locationEngine = new LocationEngineProvider(activity).obtainBestLocationEngineAvailable();
    locationEngine.setPriority(HIGH_ACCURACY);
    locationEngine.setInterval(0);
    locationEngine.setFastestInterval(1000);
    locationEngine.addLocationEngineListener(this);
    locationEngine.activate();

    if (locationEngine.getLastLocation() != null) {
        Location lastLocation = locationEngine.getLastLocation();
        onLocationChanged(lastLocation);
        currentLocation = Point.fromLngLat(lastLocation.getLongitude(), lastLocation.getLatitude());
        updateLocation(lastLocation.getLongitude(), lastLocation.getLatitude());
    }
}

         @Override
public void onLocationChanged(Location location) {
    currentLocation = Point.fromLngLat(location.getLongitude(), location.getLatitude());
    Log.e("currentlocation",location.getLatitude()+"lat"+location.getLongitude()+"lng");
    onLocationFound(location);
}

@SuppressWarnings( {"MissingPermission"})
@Override
public void onConnected() {
 locationEngine.requestLocationUpdates();
  }
   private void onLocationFound(Location location) {
    if (!locationFound) {
          animateCamera(new LatLng(location.getLatitude(),                              location.getLongitude()));
        MarkerViewOptions markerViewOptions = new MarkerViewOptions()
                .position(new LatLng(location.getLatitude(), location.getLongitude()));
        currentMarker = mapboxmap.addMarker(markerViewOptions);
        locationFound = true;

    }
}
private void animateCamera(LatLng point) {
    mapboxmap.animateCamera(CameraUpdateFactory.newLatLngZoom(point, DEFAULT_CAMERA_ZOOM), CAMERA_ANIMATION_DURATION);
}

检查 this关联。
