地理编码语言总是返回英语

 Geocoder geo = new Geocoder(getApplicationContext(), new Locale("ja"));
                        List<Address> addresses = null;
                        try {
                            addresses = geo.getFromLocation(location.getLatitude(), location.getLongitude(), 1);

                            if (addresses.size() > 0) {

                                Log.d("CITY",addresses.get(0).getLocality());
                                city.setText(addresses.get(0).getLocality());

                            } else {
                                // do your stuff
                            }
                        } catch (IOException e) {
                            e.printStackTrace();
                        }

不管用哪种语言设置,城市名称总是用英语返回!
