package jczb.shoping.model;

import java.io.Serializable;

import android.R.string;

//登录所需要的字段信息

public class loginMsg implements Serializable {

  private String avatarPath;

  private String accountNum;

  private String littleName;

  private String memberRank;

  private int growths;

  private String memberIntegral;

  public String getAvatarPath() {

    return avatarPath;

  }

  public void setAvatarPath(String avatarPath) {

    this.avatarPath = avatarPath;

  }

  public String getAccountNum() {

    return accountNum;

  }

  public void setAccountNum(String accountNum) {

    this.accountNum = accountNum;

  }

  public String getLittleName() {

    return littleName;

  }

  }

  public String getMemberIntegral() {

  }

  public void setMemberIntegral(String memberIntegral) {

}

第二个用到的FoundPassWord，具体代码如下所示：

package jczb.shoping.model;

import java.io.Serializable;

import android.R.string;

public class foundPassWord implements Serializable {

  private String phoneNumber; //手机号

  private String vlidationNum; //验证码

  private String passWord; //密码

  private String repetyPassWord; //确认密码

  public String getPhoneNumber() {

    return phoneNumber;

  }

  public void setPhoneNumber(String phoneNumber) {

    this.phoneNumber = phoneNumber;

  }

  public String getVlidationNum() {

    return vlidationNum;

  }

  public void setVlidationNum(String vlidationNum) {

    this.vlidationNum = vlidationNum;

  }

  public String getPassWord() {

    return passWord;

  }

  public void setPassWord(String passWord) {

    this.passWord = passWord;

  }

  public String getRepetyPassWord() {

    return repetyPassWord;

  }

  public void setRepetyPassWord(String repetyPassWord) {

    this.repetyPassWord = repetyPassWord;

  }

}

接着，我们来画页面，用xml对我们的登录页面进行相关布局设置，具体代码如下所示：
