Question

我想在不使用谷歌地图的情况下在我的Android项目中获得 gps location 。我开发了一项在模拟器上运行 的活动，但没有在手机上获取该位置

Answer 1

此代码显示如何获取纬度和经度。希望它有所帮助

public class GPSTracker extends Service implements LocationListener {

private final Context context;

boolean isGPSEnabled = false;
boolean isNetworkEnabled = false;
public boolean canGetLocation = false;

Location location;

double latitude;
double longitude;

private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10;
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1;

protected LocationManager locationManager;

public GPSTracker(Context context) {
    this.context = context;
    getLocation();
}

public Location getLocation() {
    try {
        locationManager = (LocationManager) context.getSystemService(LOCATION_SERVICE);

        isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);

        isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

        if(!isGPSEnabled && !isNetworkEnabled) {

        } else {
            this.canGetLocation = true;

            if (isNetworkEnabled) {

                        MIN_TIME_BW_UPDATES,
                        MIN_DISTANCE_CHANGE_FOR_UPDATES, this);

                    location = locationManager
                            .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

            }
        }

    } catch (Exception e) {
        e.printStackTrace();
    }

    return location;
}


public void stopUsingGPS() {
    if(locationManager != null) {
        locationManager.removeUpdates(GPSTracker.this);

        longitude = location.getLongitude();
    }

    return longitude;
}

public boolean canGetLocation() {
    return this.canGetLocation;
}

public void showSettingsAlert() {
    AlertDialog.Builder alertDialog = new AlertDialog.Builder(context);

    alertDialog.setTitle("GPS is settings");

    alertDialog.setMessage("Turn on your GPS to find nearby helpers");

    alertDialog.setPositiveButton("Settings", new DialogInterface.OnClickListener() {

            Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);

@Override

    // TODO Auto-generated method stub

}

@Override

请下载此源代码，它将帮助您获得Lattitude和Longitude。 :)从这两个你可以得到你的位置。希望这会有所帮助..

Answer 3

您可以通过两种方式获取当前位置首先是使用GPS本机api，其次是使用goolge map库来做到这一点第一种方式是

// Acquire a reference to the system Location Manager
LocationManager locationManager = (LocationManager)this.getSystemService(Context.LOCATION_SERVICE);

// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
  // Called when a new location is found by the network location provider.
  makeUseOfNewLocation(location);
}

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

public void onProviderEnabled(String provider) {}

public void onProviderDisabled(String provider) {}
  };

// Register the listener with the Location Manager to receive location updates
       locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);

通过GPS纬度和经度简单获取当前位置：

首先放入你的AndroidManifest.xml：
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

然后询问用户是否有权访问精确位置：

public void fineLocation(Activity activity) {
    ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, 1);
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String permissions[], @NonNull int[] grantResults) {
    if (requestCode == 1) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // get location because permission is granted.
        }
    }
}

然后获得当前的纬度和经度：

@SuppressWarnings("ResourceType")
public void gpsLoc(Context context) {
   android.location.LocationManager manager = (android.location.LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
   if (manager != null) {
      for (String provider : manager.getAllProviders()) {
         Location location = manager.getLastKnownLocation(provider);
         if (location != null) {
            double lat = location.getLatitude();
            double lon = location.getLongitude();
         }
      }
   }
}

Answer 5

试试这个

@SuppressWarnings("ResourceType")
public void gpsLoc(Context context) {
android.location.LocationManager manager = (android.location.LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
if (manager != null) {
  for (String provider : manager.getAllProviders()) {
     Location location = manager.getLastKnownLocation(provider);
     if (location != null) {
        double lat = location.getLatitude();
        double lon = location.getLongitude();
     }
   }
 }
}
