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

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

LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
        // 当位置变化时触发
        double latitude = location.getLatitude();
        double longitude = location.getLongitude();
        // 根据经纬度获取城市信息
        String city = getCityFromCoordinates(latitude, longitude);
        // 处理获取到的城市信息
        handleCity(city);
    }

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

    public void onProviderEnabled(String provider) {}

    public void onProviderDisabled(String provider) {}
};

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);

private String getCityFromCoordinates(double latitude, double longitude) {
    Geocoder geocoder = new Geocoder(this, Locale.getDefault());
    try {
        List<Address> addresses = geocoder.getFromLocation(latitude, longitude, 1);
        if (addresses.size() > 0) {
            Address address = addresses.get(0);
            return address.getLocality();
        }
    } catch (IOException e) {
        e.printStackTrace();
