 */

public interface iusermodel {
 void setfirstname(string firstname);

 void setlastname(string lastname);

 string getfirstname();

 string getlastname();

 //根据id获取对象
 userbean load(int id);
}

import android.util.log;

import com.bwei.mvps.bean.userbean;

/**
 * 1. 类的用途
 * 2. @author forever
 * 3. @date 2017/9/1 16:04
 */

public class usermodel implements iusermodel {
 @override

 log.i("xxx", lastname);

 }

 @override
 public string getfirstname() {
 return null;
 }

 @override
 public string getlastname() {
 return null;
 }

 @override
 public userbean load(int id) {
 //查询数据库或联网获取数据
 log.i("fff", id + "");

 return new userbean("张", "三");
 }
}

view包

/**
