私の場所にGoogleマップカメラがないのはなぜですか？

Question

私は私が私の場所にカメラをしたいが、カメラは他の場所にあり、私はこの起こる 誰もがこれはこの状況が

が起こる理由を見つける私を助けることができる理由を知らない、フラグメントアンドロイドでGoogleマップのコードを持っています私の断片コード：

public class FragmentMap extends Fragment implements LocationListener { 

MapView mapView; 
GoogleMap map; 
double latitude; 
double longitude; 
public String bestProvider; 
public Criteria criteria; 


@Override 
public void onLocationChanged(Location location) { 

    // Getting latitude of the current location 
    latitude = location.getLatitude(); 

    // Getting longitude of the current location 
    longitude = location.getLongitude(); 

    // Creating a LatLng object for the current location 
    LatLng latLng = new LatLng(latitude, longitude); 

    // Showing the current location in Google Map 
    map.moveCamera(CameraUpdateFactory.newLatLng(latLng)); 

    // Zoom in the Google Map 
    map.animateCamera(CameraUpdateFactory.zoomTo(15)); 

} 

@Override 
public void onStatusChanged(String provider, int status, Bundle extras) { 

} 

@Override 
public void onProviderEnabled(String provider) { 

} 

@Override 
public void onProviderDisabled(String provider) { 

} 


@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    View v = inflater.inflate(R.layout.map_fragment, container, false); 

    // Gets the MapView from the XML layout and creates it 
    mapView = (MapView) v.findViewById(R.id.mapview); 
    mapView.onCreate(savedInstanceState); 

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


    // Needs to call MapsInitializer before doing any CameraUpdateFactory calls 
    MapsInitializer.initialize(this.getActivity()); 

    // Updates the location and zoom of the MapView 
    map.setMyLocationEnabled(true); 

    criteria = new Criteria(); 
    bestProvider = String.valueOf(MainActivity.locationManager.getBestProvider(criteria, true)).toString(); 
    Location location = MainActivity.locationManager.getLastKnownLocation(bestProvider); 

    if (location != null) { 
     onLocationChanged(location); 
    } 

    CameraUpdate cameraUpdate = 
      CameraUpdateFactory 
        .newLatLngZoom(new LatLng(location.getLatitude(), location.getLongitude()), 16); 
    map.animateCamera(cameraUpdate); 

    return v; 
} 

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

@Override 
public void onDestroy() { 
    super.onDestroy(); 
    mapView.onDestroy(); 
} 

@Override 
public void onLowMemory() { 
    super.onLowMemory(); 
    mapView.onLowMemory(); 
} 

}

これは私の場所の宣言である：

public static LocationManager locationManager; 
    locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

あなたonlocationchangeはする必要があります -

@Override 
public void onLocationChanged(Location location) { 

CameraPosition cameraPosition = new CameraPosition.Builder() 
       .target(new LatLng(location.getLatitude(), location.getLongitude())) 
       .zoom(14) 
       .build(); 

if (map != null) { 
    map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition)); 
} 

} 

これはあなたの現在の場所にカメラを移動します。

私はそれがあなたのために働くかどうか教えてください。
