获得经度和纬度的Android总是返回0.0

我正在尝试获取 android的经度和纬度,这是我的代码：

LocationManager locationManager = (LocationManager)
            this_activity.getSystemService(Context.LOCATION_SERVICE);

    LocationListener locationListener = new MyLocationListener();
    locationManager.requestLocationUpdates(
            LocationManager.GPS_PROVIDER,5000,10,locationListener);




 public class MyLocationListener implements LocationListener {

    @Override
    public void onLocationChanged(Location loc) {
        longitude = Double.toString(loc.getLongitude());
        latitude = Double.toString(loc.getLatitude());
    }

    @Override
    public void onProviderdisabled(String provider) {}

    @Override
    public void onProviderEnabled(String provider) {}

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

清单Permissions：

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

经度和纬度我总是得到0.0秒

解决方法

除了@AshishPedhadiya提到你只听GPS提供商的权限.

LocationListener locationListener = new MyLocationListener();
locationManager.requestLocationUpdates(
        LocationManager.GPS_PROVIDER,locationListener);

GPS无法在里面工作.因此,当您测试应用程序时,它几乎总是会返回(0,0)位置.您可能也想收听NETWORK_PROVIDER,如果没有GPS位置,它会估计来自手机信号塔和WiFi点的位置.

locationManager.requestLocationUpdates(
        LocationManager.NETWORK_PROVIDER,locationListener);

此外,要获取快速地理位置,请查看Application.getLastKNownLocation()方法.
