                    public void onSelected(String... citySelected) {
                        //省份
                        String province = citySelected[0];
                        //城市
                        String city = citySelected[1];
                        //区县
                        String district = citySelected[2];
                        //邮编
                        String code = citySelected[3];
                        //控件自己写两个edittext或者Xedittext用来显示文本代替下面两个个控件ID
                        //address_new_address用来展示地址
                        //address_new_zipcode用来展示邮编
                        address_new_address.setText(province + "-" + city + "-" + district);
                        address_new_zipcode.setText(code);
                    }
                });
                cityPickerView.show();
