我想从android访问jsonarray

Question

大家好我有>>> any('bob' == j.name for j in i) True 没有钥匙或者＃34;标题＆＃34;如下

JSONArray

如何访问数组中的每个对象，我看到的所有示例都包含列表前的标题或名称，但是这个没有名称，因此我可以在[ { "messages_PK_ID": 429, "messages_Name": "اختبار المنهج التأسيسي1", "messages_ToSendDateDiff": 365, "message_URL": "<p style=\"text-align: center;\"><a href=\"http://www.iacademypd.com/LevelExamLogin.aspx\"><img alt=\"\" src=\"http://iacademypd.com/AttachFiles/Level1.jpg\" /></a></p>", "messageType_Name": "بطاقة", "message_FKID_MessageType": 1, "sendEmailAuditTrial_DayNo": 365, "sendEmailAuditTrial_Type": 1, "sendEmailAuditTrial_Datetime": "2012-02-24T10:05:39.587", "messages_Year": 1, "message_URL_New": "http://www.iacademypd.com/LevelExamLogin.aspx" }, { "messages_PK_ID": 428, "messages_Name": "البطاقة/364", "messages_ToSendDateDiff": 364, "message_URL": "<p><img alt=\"\" src=\"http://iacademypd.com/AttachFiles/card-364aaa.jpg\" /></p>", "messageType_Name": "بطاقة", "message_FKID_MessageType": 1, "sendEmailAuditTrial_DayNo": 364, "sendEmailAuditTrial_Type": 1, "sendEmailAuditTrial_Datetime": "2012-02-24T10:05:39.58", "messages_Year": 1, "message_URL_New": "http://iacademypd.com/AttachFiles/card-364aaa.jpg" },....and so on 中指定< / p>

有什么建议吗？

Answer 1

请将RoboPojo Generator用于Android Studio，它将帮助您为您创建模型类，并直接将SetData设置为您的模型类。

如果您使用Gson来设置数据。

在ilink下面帮助你：

希望这会对你有所帮助。

Answer 2

使用Gson Library解析这个json最简单的方法

compile 'com.google.code.gson:gson:2.8.1'

使用think来解析http://www.jsonschema2pojo.org/

你会得到像这样的pojo课程 的 1.User.Java

    public class User {

    @SerializedName("messages_PK_ID")
    @Expose
    private Integer messagesPKID;
    @SerializedName("messages_Name")
    @Expose
    private String messagesName;
    @SerializedName("messages_ToSendDateDiff")
    @Expose
    private Integer messagesToSendDateDiff;
    @SerializedName("message_URL")
    @Expose
    private String messageURL;
    @SerializedName("messageType_Name")
    @Expose
    private String messageTypeName;
    @SerializedName("message_FKID_MessageType")
    @Expose
    private Integer messageFKIDMessageType;
    @SerializedName("sendEmailAuditTrial_DayNo")
    @Expose
    private Integer sendEmailAuditTrialDayNo;
    @SerializedName("sendEmailAuditTrial_Type")
    @Expose
    private Integer sendEmailAuditTrialType;
    @SerializedName("sendEmailAuditTrial_Datetime")
    @Expose
    private String sendEmailAuditTrialDatetime;
    @SerializedName("messages_Year")
    @Expose
    private Integer messagesYear;
    @SerializedName("message_URL_New")
    @Expose
    private String messageURLNew;

    public Integer getMessagesPKID() {
    return messagesPKID;
    }

    public void setMessagesPKID(Integer messagesPKID) {
    this.messagesPKID = messagesPKID;
    }

    public String getMessagesName() {
    return messagesName;
    }

    public void setMessagesName(String messagesName) {
    this.messagesName = messagesName;
    }

    public Integer getMessagesToSendDateDiff() {
    return messagesToSendDateDiff;
    }

    public void setMessagesToSendDateDiff(Integer messagesToSendDateDiff) {
    this.messagesToSendDateDiff = messagesToSendDateDiff;
    }

    public String getMessageURL() {
    return messageURL;
    }

    public void setMessageURL(String messageURL) {
    this.messageURL = messageURL;
    }

    public String getMessageTypeName() {
    return messageTypeName;
    }

    public void setMessageTypeName(String messageTypeName) {
    this.messageTypeName = messageTypeName;
    }

    public Integer getMessageFKIDMessageType() {
    return messageFKIDMessageType;
    }

    public void setMessageFKIDMessageType(Integer messageFKIDMessageType) {
    this.messageFKIDMessageType = messageFKIDMessageType;
    }

    public Integer getSendEmailAuditTrialDayNo() {
    return sendEmailAuditTrialDayNo;
    }

    public void setSendEmailAuditTrialDayNo(Integer sendEmailAuditTrialDayNo) {
    this.sendEmailAuditTrialDayNo = sendEmailAuditTrialDayNo;
    }

    public Integer getSendEmailAuditTrialType() {
    return sendEmailAuditTrialType;
    }

    public void setSendEmailAuditTrialType(Integer sendEmailAuditTrialType) {
    this.sendEmailAuditTrialType = sendEmailAuditTrialType;
    }

    public String getSendEmailAuditTrialDatetime() {
    return sendEmailAuditTrialDatetime;
    }

    public void setSendEmailAuditTrialDatetime(String sendEmailAuditTrialDatetime) {
    this.sendEmailAuditTrialDatetime = sendEmailAuditTrialDatetime;
    }

    public Integer getMessagesYear() {
    return messagesYear;
    }

    public void setMessagesYear(Integer messagesYear) {
    this.messagesYear = messagesYear;
    }

    public String getMessageURLNew() {
    return messageURLNew;
    }

    public void setMessageURLNew(String messageURLNew) {
    this.messageURLNew = messageURLNew;
    }

    }

在解析了json之后，你必须像这样使用解析

     Gson mGson=new Gson();
     ArrayList<User>  userArrayList=new ArrayList<>();
     JsonArray jsonElements=new JsonArray("your Json Array");
     for (int i = 0; i < jsonElements.size(); i++) {
     User user=new User();
     user=mGson.fromJson(jsonElements.get(i).getJsonObject().toString(),User.class);
     userArrayList.add(user);
     }

//你可以像这样访问 userArrayList.get（0）.getMessagesName（）; //第一个对象项目

如上所述，您可以访问响应pojo。
