Android原生定位

使用LocationManager和LocationListener结合进行简单定位功能

1.创建LocationManager

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

2.创建LocationListener

private final LocationListener locationListener = new LocationListener() {

        public void onLocationChanged(Location location) {
            if (location != null) {
                //经度
                double longitude = location.getLongitude();
                //纬度
                double latitude = location.getLatitude();
            } else {
                if (locationIndex >= 0) {
                    final String errorMessage = "定位失败，请重新定位";
                }
            }
        }

        public void onProviderDisabled(String provider) {
        }

        public void onProviderEnabled(String provider) {
        }

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

3.绑定

List<String> providers = locationManager.getProviders(true);
        for (String provider : providers) { 
            if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                // TODO: Consider calling
                //    ActivityCompat#requestPermissions
                // 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 ActivityCompat#requestPermissions for more details.
             return;
            }
            locationManager.requestLocationUpdates(provider, 0, 0, locationListener);
        }
