【问题描述】：

我是新手，很难将我的 JSonObject 保存到我的 Beanclass *这是 JSON 对象：* 关于这个 LOC 的结果：

 JSONObject responseJson;
 Log.i("LoginActivity",responseJson.toString());

11-28 22:15:56.525: I/LoginActivity(22793): {"message":"Successfully Logged In.","auths":"Global Administrator,Installer,KONG,Project Manager,SendPdfToCustomerRole,Surveyor" ,"user":{"view_all_proposals":"0","role_id":"1","contact_no":"020 8547 4333 (x354)","date_modified":"2013-10-10 10:08:07 ","status":"ACTIVE","profit_margin_limit":"","cash_code":"KHO","date_created":"2013-02-03 06:41:41","user_initials":"KHO", "密码":"f10343d1dc8d44c8935b356aa3f8aae2","id":"27","first_name":"Kong","用户名":"kong","is_admin":"0","地址":"技术经理","电子邮件":"kong.hoang@mrfsgroup.com","proposal_review":"3000000","last_name":"Hoang","ldap_authentication":"0"},"status":true,"apkStatus":true, "apkFileDate":"2013-11-25 05:07:27","apkFile":"34_SurveyAppNew.apk"}

和我的 Bean 类：

public class LoginBean {
private int id;
private String username;
private String password;
private String email;
private String status;
private Date ACTIVE;
private Date dateCreated;
private Date dateModified;
private String isAdmin; // is '0'
private String userInitials;
private int roleId;
private String firstName;
private String lastName;
private String contactNo;
private String address;
private String profitMarginLimit;

/**
 * @return the id
 */
public int getId() {
    return id;
}
/**
 * @param id the id to set
 */
public void setId(int id) {
    this.id = id;
}
/**
 * @return the username
 */
public String getUsername() {
    return username;
}
/**
 * @param username the username to set
 */
public void setUsername(String username) {
    this.username = username;
}
/**
 * @return the password
 */
public String getPassword() {
    return password;
}
/**
 * @param password the password to set
 */
public void setPassword(String password) {
    this.password = password;
}
/**
 * @return the email
 */
public String getEmail() {
    return email;
}
/**
 * @param email the email to set
 */
public void setEmail(String email) {
    this.email = email;
}
/**
 * @return the status
 */
public String getStatus() {
    return status;
}
/**
 * @param status the status to set
 */
public void setStatus(String status) {
    this.status = status;
}
/**
 * @return the aCTIVE
 */
public Date getACTIVE() {
    return ACTIVE;
}
/**
 * @param aCTIVE the aCTIVE to set
 */
public void setACTIVE(Date aCTIVE) {
    ACTIVE = aCTIVE;
}
/**
 * @return the dateCreated
 */
public Date getDateCreated() {
    return dateCreated;
}
/**
 * @param dateCreated the dateCreated to set
 */
public void setDateCreated(Date dateCreated) {
    this.dateCreated = dateCreated;
}
/**
 * @return the dateModified
 */
public Date getDateModified() {
    return dateModified;
}
/**
 * @param dateModified the dateModified to set
 */
public void setDateModified(Date dateModified) {
    this.dateModified = dateModified;
}
/**
 * @return the isAdmin
 */
public String getIsAdmin() {
    return isAdmin;
}
/**
 * @param isAdmin the isAdmin to set
 */
public void setIsAdmin(String isAdmin) {
    this.isAdmin = isAdmin;
}
/**
 * @return the userInitials
 */
public String getUserInitials() {
    return userInitials;
}
/**
 * @param userInitials the userInitials to set
 */
public void setUserInitials(String userInitials) {
    this.userInitials = userInitials;
}
/**
 * @return the roleId
 */
public int getRoleId() {
    return roleId;
}
/**
 * @param roleId the roleId to set
 */
public void setRoleId(int roleId) {
    this.roleId = roleId;
}
/**
 * @return the firstName
 */
public String getFirstName() {
    return firstName;
}
/**
 * @param firstName the firstName to set
 */
public void setFirstName(String firstName) {
    this.firstName = firstName;
}
/**
 * @return the lastName
 */
public String getLastName() {
    return lastName;
}
/**
 * @param lastName the lastName to set
 */
public void setLastName(String lastName) {
    this.lastName = lastName;
}
/**
 * @return the contactNo
 */
public String getContactNo() {
    return contactNo;
}
/**
 * @param contactNo the contactNo to set
 */
public void setContactNo(String contactNo) {
    this.contactNo = contactNo;
}
/**
 * @return the address
 */
public String getAddress() {
    return address;
}
/**
 * @param address the address to set
 */
public void setAddress(String address) {
    this.address = address;
}
/**
 * @return the profitMarginLimit
 */
public String getProfitMarginLimit() {
    return profitMarginLimit;
}
/**
 * @param profitMarginLimit the profitMarginLimit to set
 */
public void setProfitMarginLimit(String profitMarginLimit) {
    this.profitMarginLimit = profitMarginLimit;
}
}

有人可以指导我如何将 JSON 响应保存到我的 BeanClass 中。

【解决方案1】：

您可以通过很多行代码来完成。由于您是新手，我不建议您使用此库Gson，但它会解决您的问题。它只是使用Gson 的一行代码

使用 Gson...

Gson gson = new Gson();
Loginbean bean = new LoginBean(......); // Your constructor 
bean.setXYZ(....); // If you want
String json = gson.toJson(bean);
// And
LoginBean gotFromJson = gson.fromJson(json, LoginBean.class);
// Where json is the JSON you got from response
// You can get all the values of your fields here. like...
int id = gotFromJson.getId();
// and other getters. it will still return the values.

You can find Gson here

【讨论】：

是的，我已经在我的代码中使用了 Gson，但我不知道如何将所有值从 jsonResponse 插入到 BeanClass
如何插入来自 jsonresponse 的所有值？我不明白。您将获得一个包含所有值的 Loginbean 对象。您可以调用 getter 来检索字段的值。
@user1668447 请参考编辑。如果您有任何问题，请询问
不，您不必使用 set 添加任何值。声明LoginBean gotFromJson = gson.fromJson(json, LoginBean.class); 将为您做所有事情。试试上面的代码。你会明白的。这里gotFromJson 是你的LoginBean 对象。

我认为你确实需要这个
