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);
