Question

我有一些由LocationManager支持的GPS坐标。当设备连接到互联网时，我必须检查我去过哪个国家。是否有任何服务允许您发送GPS位置并接收国家/地区作为回应？

您可以使用它来获取在给定的经度和纬度中存储为地址的所有详细信息。

LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
String provider = locationManager.getBestProvider(new Criteria(), true);

Location locations = locationManager.getLastKnownLocation(provider);
List<String>  providerList = locationManager.getAllProviders();
if(null!=locations && null!=providerList && providerList.size()>0){                 
double longitude = locations.getLongitude();
double latitude = locations.getLatitude();
Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.getDefault());                 
try {
    List<Address> listAddresses = geocoder.getFromLocation(latitude, longitude, 1);
    if(null!=listAddresses&&listAddresses.size()>0){
        String _Location = listAddresses.get(0).getAddressLine(0);
    }
} catch (IOException e) {
    e.printStackTrace();
}

}

如果您需要有关经度和纬度的更多详细信息，可以这样做，

public void getAddress(double lat, double lng) {
    Geocoder geocoder = new Geocoder(HomeActivity.mContext, Locale.getDefault());
    try {
        List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);
        Address obj = addresses.get(0);
        String add = obj.getAddressLine(0);
        GUIStatics.currentAddress = obj.getSubAdminArea() + ","
                + obj.getAdminArea();
        GUIStatics.latitude = obj.getLatitude();
        GUIStatics.longitude = obj.getLongitude();
        GUIStatics.currentCity= obj.getSubAdminArea();
        GUIStatics.currentState= obj.getAdminArea();
        add = add + "\n" + obj.getCountryName();
        add = add + "\n" + obj.getCountryCode();
        add = add + "\n" + obj.getAdminArea();
        add = add + "\n" + obj.getPostalCode();
        add = add + "\n" + obj.getSubAdminArea();
        add = add + "\n" + obj.getLocality();
        add = add + "\n" + obj.getSubThoroughfare();

        Log.v("IGA", "Address" + add);
        // Toast.makeText(this, "Address=>" + add,
        // Toast.LENGTH_SHORT).show();

        // TennisAppActivity.showDialog(add);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
    }
}

不要忘记在清单文件中添加权限。

使用Geocoder，你可以得到这样的国家：

private String getCountry(double latitude, double longitude) {
        try {
            List<Address> addresses;
            Geocoder geocoder = new Geocoder(getActivity(), Locale.getDefault());
            addresses = geocoder.getFromLocation(latitude, longitude, 1); 
            return addresses.get(0).getCountryName();;
        } catch (IOException e) {
            e.printStackTrace();
        }
        return  "Unknown address";
    }

通过GPS坐标确定国家
