1.M:bean：

package com.example.mvp4android.bean;public class UserBean {    private String username;    private String password;    public String getUsername() {        return username;    }    public UserBean() {        super();        // TODO Auto-generated constructor stub    }    public void setUsername(String username) {        this.username = username;    }    public String getPassword() {        return password;    }    public UserBean(String username, String password) {        super();        this.username = username;        this.password = password;    }    public void setPassword(String password) {        this.password = password;    }}

2.M:interface

package com.example.mvp4android.biz;public interface IUserBiz {    public void login(String username, String password, OnLoginListener loginListener);}

M: interface-clicklistener

package com.example.mvp4android.biz;import com.example.mvp4android.bean.UserBean;public interface OnLoginListener {    void loginSuccess(UserBean user);    void loginFailed();}
