登录界面的实现要求
对于UI界面的设置就不赘述了，只是普通的控件；
考虑到登录逻辑问题，一开始我们是没有账号的，所以需要进行注册功能的编辑；为了模拟登录效果，我们需要将用户注册的账户和密码发送到网络上。然后在登录界面将上传的数据获取下来进行比对从而登录成功；
上传和下载数据所需要的bean类：
BaseBean:用于一开始的手机号和密码的上传：
public class BaseBean {
public int code;
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
}
LoginBean:用以获取是否登录成功和用户数据：
private Object age;
private String createtime;
private int gender;
private Object icon;
private String mobile;
private int money;
private Object nickname;
private String password;
private int uid;
private String username;
进行get，set的设置即可；
User用户信息：
private String userName;
private String pwd;
设置有参、无参、get、set即可；
Register ：注册所用bean类：
private String msg;
private String code;
private DataBean data;
public static class DataBean {
private Object age;
private Object createtime;
private int gender;
private Object icon;
private String mobile;
private int money;
private Object nickname;
private String password;
private int uid;
private String username;
}
获取用户信息的方法类：
接口类：IUserModel:
public interface IUserModel {
public void setUserName(String userName);
public void setPwd(String pwd);
public User getUser();
}
//定义获取用户账号和密码的两个方法；
调用接口的用户类：UserModel:
User user = new User();
@Override
public void setUserName(String userName) {
user.setUserName(userName);
}
@Override
public void setPwd(String pwd) {
user.setPwd(pwd);
}
@Override
public User getUser() {
return user;
}
}
