未获取 GPS 位置，但 Google 地图显示当前位置答案

【问题标题】：Not getting GPS location, though Google map is showing current location未获取 GPS 位置，但 Google 地图显示当前位置

【问题描述】：

我没有在我的代码中获取 GPS 位置，而 Google 地图正在显示当前位置甚至更新，我正在启动一个服务，在服务内将 locationListener 注册到 locationManager，处理 onLocationChanged 回调方法，在 AndroidManifest 中进行条目。 xml 甚至。正在显示日志 onCreate 方法。
下面是我的代码，你们能告诉我我哪里做错了......

public class LocationService extends Service implements LocationListener {
private static final long MIN_TIME_INTERVAL_FOR_GPS_LOCATION = 100;
private static final float MIN_DISTANCE_INTERVAL_FOR_GPS_LOCATION = 1.0f;
private static String TAG = LocationService.class.getSimpleName();
private LocationManager locationManager;
private static Location mCurrentLocation;

@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public void onCreate() {
    super.onCreate();
    Log.i(TAG, "onCreate...");

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, MIN_TIME_INTERVAL_FOR_GPS_LOCATION, MIN_DISTANCE_INTERVAL_FOR_GPS_LOCATION, this);
    mCurrentLocation = getBestLocation();
}

private Location getBestLocation() {
    Log.i(TAG, "getBestLocation...");
    Location location_gps = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
    Location location_network = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

    // If both are available, get the most recent
    if (location_gps != null && location_network != null) {
        return (location_gps.getTime() > location_network.getTime()) ? location_gps : location_network;
    } else if (location_gps == null && location_network == null) {
        return null;
    } else {
        return (location_gps == null) ? location_network : location_gps;
    }
}

@Override
public void onLocationChanged(Location location) {
    Log.i(TAG, "onLocationChanged...");
    Toast.makeText(LocationService.this, "Location Found", Toast.LENGTH_SHORT).show();
    mCurrentLocation = location;
}

@Override
public void onProviderDisabled(String provider) {
}

@Override
public void onProviderEnabled(String provider) {
}

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

public static Location getmCurrentLocation() {
    return mCurrentLocation;
}

public static void setmCurrentLocation(Location mCurrentLocation) {
    LocationService.mCurrentLocation = mCurrentLocation;
}

@Override
public void onDestroy() {
    super.onDestroy();
    Log.i(TAG, "onDestroy...");
    locationManager.removeUpdates(this);
}
}

【问题讨论】：

使用像谷歌地图这样的融合位置提供者..

【解决方案1】：

您的 locationManager 仅使用 GPS 提供程序调用 requestLocationUpdates。

我认为您的设备无法捕捉到 GPS 卫星信号，室内状态。
因此，您也应该使用网络提供商调用 requestLocationUpdates。

【讨论】：

所以你是说我也可以同时为其他提供者注册 locationListener ？
是.. 类 LocationService 扩展服务 { LocationListener gpsListener = new Location Listener { } LocationListener networkListener = new Location Listener { } }
