本文实例为大家分享了Android封装MVP实现登录注册功能,供大家参考,具体内容如下

model包:


import com.bwei.mvps.bean.UserBean;

/**
* 1. 类的用途
* 2. @author forever
* 3. @date 2017/9/1 16:00
*/

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
public void setFirstName(String firstName) {
Log.i("xxx", firstName);
}

@Override
public void setLastName(String lastName) {
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


/**
* 1. 类的用途
* 2. @author forever
* 3. @date 2017/9/1 15:53
*/

public interface UserView {
void setFirstName(String firstName);

void setLastName(String lastName);

int getId();

String getFirstName();

String getLastName();
}

presenter包:


import android.util.Log;

import com.bwei.mvps.MainActivity;
import com.bwei.mvps.bean.UserBean;
import com.bwei.mvps.model.IUserModel;
import com.bwei.mvps.model.UserModel;
import com.bwei.mvps.view.UserView;

/**
* 1. 类的用途
* 2. @author forever
* 3. @date 2017/9/1 16:05
*/

public class UserPresenter {

private UserView userview;
private final IUserModel iUserModel;

public UserPresenter(UserView userview) {
this.userview = userview;
iUserModel = new UserModel();

}

//保存数据
public void saveUser(int id, String firstName, String lastName) {
UserBean userBean = iUserModel.load(id);
Log.i("sss", "id:" + id + ",firstName:" + firstName + ",lastName:" + lastName);

}

//查询数据
public void find(int id) {
UserBean userBean = iUserModel.load(id);
String firstName = userBean.getFirstName();
String lastName = userBean.getLastName();
userview.setFirstName(firstName);
userview.setLastName(lastName);

Log.i("aaa", "id:" + id + ",firstName:" + firstName + ",lastName:" + lastName);

}
}
