Um den aktuellen Standort

Question

Ich verwende den folgenden Code zu erhalten, um den Standort eines Benutzers zu erhalten

public class MainLocation extends Application implements LocationListener { 
protected LocationManager locationManager; 
protected LocationListener locationListener; 
protected Context context; 
String lat; 
String provider; 
protected String latitude, longitude; 
protected boolean gps_enabled, network_enabled; 

@Override 
public void onCreate() { 
    super.onCreate(); 

    Log.e("Location", "here"); 

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 
     if (checkSelfPermission(Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { 
      // TODO: Consider calling 
      // public void requestPermissions(@NonNull String[] permissions, int requestCode) 
      // here to request the missing permissions, and then overriding 
      // public void onRequestPermissionsResult(int requestCode, String[] permissions, 
      //           int[] grantResults) 
      // to handle the case where the user grants the permission. See the documentation 
      // for Activity#requestPermissions for more details. 
      return; 
     } 
    } 
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this); 


} 

@Override 
public void onLocationChanged(Location location) { 
    Log.e("Location", "" + location.getLatitude()); 
} 

@Override 
public void onStatusChanged(String provider, int status, Bundle extras) { 
    Log.e("Location Status", "" + provider + " " + status + " " + extras); 
} 

@Override 
public void onProviderEnabled(String provider) { 
    Log.e("Location", "Enabled"); 
} 

@Override 
public void onProviderDisabled(String provider) { 
    Log.e("Location","Disabled"+provider); 

} 

}

aber hier ist die OnLocationChanged Funktion wird nie bekommen, so genannt, im die Lage nicht in der Lage holen . Wie kann ich den Standort bekommen? Im logcat wird die Registerkarte Info Breite und Länge unter dem Titel zeigt onLocationReceived“.

Dies ist das Manifest ist,

Die Google Play services location APIs werden über die Android Framework Lage APIs bevorzugt (android.location) als eine Möglichkeit, Standorterkennung, um Ihre Anwendung hinzuzufügen.

können Sie das Beispiel zu finden, wie es zu benutzen, rechts here.

PS vergessen Sie nicht, Überprüfen Sie, ob auf Ihrem Gerät Berechtigungen erteilt wurden, wenn Sie Berechtigungen in die Manifestdatei hinzugefügt haben ...
