无法将JSON转换为Java POJO类？

3

我想将这个JSON转换为列表并插入到RecyclerView中，但是由于它给出了3个类，所以我无法实现。那么，如何将这个类转换为父类呢？有谁可以帮助我，这样我就可以制作响应列表并将其放入RecyclerView中。

三个类是什么意思？它是一个包含两个对象的数组。 - MetaSnarf

请您提供一下你的课程信息好吗？ - Nisheeth Shah

@RakshitNawani 是的，我知道，我需要做的是让父类给我整个响应！你有什么办法吗？ - Mohamed El Fwakhry

我使用http://www.jsonschema2pojo.org/创建自己的响应类，您可以根据需要进行自定义尝试。 - Rakshit Nawani

我推荐你在Android Studio中使用这个插件：https://plugins.jetbrains.com/plugin/7654-gsonformat。 - Kingfisher Phuoc

如果我理解你的问题正确，我相信这就是你的意思。请使用此内容。

创建一个像这样的POJO类。

public abstract class TempClass {

    @Expose
    @SerializedName("updated_at")
    private UpdatedAt updatedAt;
    @Expose
    @SerializedName("created_at")
    private CreatedAt createdAt;
    @Expose
    @SerializedName("photo")
    private String photo;
    @Expose
    @SerializedName("address_en")
    private String addressEn;
    @Expose
    @SerializedName("address_ar")
    private String addressAr;
    @Expose
    @SerializedName("mobile")
    private String mobile;
    @Expose
    @SerializedName("description_en")
    private String descriptionEn;
    @Expose
    @SerializedName("description_ar")
    private String descriptionAr;
    @Expose
    @SerializedName("name_en")
    private String nameEn;
    @Expose
    @SerializedName("name_ar")
    private String nameAr;
    @Expose
    @SerializedName("id")
    private int id;

    public UpdatedAt getUpdatedAt() {
        return updatedAt;
    }

    public void setUpdatedAt(UpdatedAt updatedAt) {
        this.updatedAt = updatedAt;
    }

    public CreatedAt getCreatedAt() {
        return createdAt;
    }

    public void setCreatedAt(CreatedAt createdAt) {
        this.createdAt = createdAt;
    }

    public String getPhoto() {
        return photo;
    }

    public void setPhoto(String photo) {
        this.photo = photo;
    }

    public String getAddressEn() {
        return addressEn;
    }

    public void setAddressEn(String addressEn) {
        this.addressEn = addressEn;
    }

    public String getAddressAr() {
        return addressAr;
    }

    public void setAddressAr(String addressAr) {
        this.addressAr = addressAr;
    }

    public String getMobile() {
        return mobile;
    }

    public void setMobile(String mobile) {
        this.mobile = mobile;
    }

    public String getDescriptionEn() {
        return descriptionEn;
    }

    public void setDescriptionEn(String descriptionEn) {
        this.descriptionEn = descriptionEn;
    }

    public String getDescriptionAr() {
        return descriptionAr;
    }

    public void setDescriptionAr(String descriptionAr) {
        this.descriptionAr = descriptionAr;
    }

    public String getNameEn() {
        return nameEn;
    }

    public void setNameEn(String nameEn) {
        this.nameEn = nameEn;
    }

    public String getNameAr() {
        return nameAr;
    }

    public void setNameAr(String nameAr) {
        this.nameAr = nameAr;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public static class UpdatedAt {
        @Expose
        @SerializedName("timezone")
        private String timezone;
        @Expose
        @SerializedName("timezone_type")
        private int timezoneType;
        @Expose
        @SerializedName("date")
        private String date;

        public String getTimezone() {
            return timezone;
        }

        public void setTimezone(String timezone) {
            this.timezone = timezone;
        }

        public int getTimezoneType() {
            return timezoneType;
        }

        public void setTimezoneType(int timezoneType) {
            this.timezoneType = timezoneType;
        }

        public String getDate() {
            return date;
        }

        public void setDate(String date) {
            this.date = date;
        }
    }

    public static class CreatedAt {
        @Expose
        @SerializedName("timezone")
        private String timezone;
        @Expose
        @SerializedName("timezone_type")
        private int timezoneType;
        @Expose
        @SerializedName("date")
        private String date;

        public String getTimezone() {
            return timezone;
        }

        public void setTimezone(String timezone) {
            this.timezone = timezone;
        }

        public int getTimezoneType() {
            return timezoneType;
        }

        public void setTimezoneType(int timezoneType) {
            this.timezoneType = timezoneType;
        }

        public String getDate() {
            return date;
        }

        public void setDate(String date) {
            this.date = date;
        }
    }
}

现在可以像这样访问内部类，请查看以下内容。

ArrayList<TempClass> item = new ArrayList<>();

item.get(holder.getAdapterPosition()).getUpdatedAt().getDate();//here access the UpdatedAt class object method. 

item.get(holder.getAdapterPosition()).getCreatedAt().getDate();// here access the CreatedAt class object method.

我的方法是：

使用GSON库。

我创建了两个模型类

主类，它包含每个数组项的信息
自定义日期类，它包含您的日期信息 created_at和updated_at属性

class MyDate{ public String date; public int timezone_type; public String timezone }

class Info{ public String id; public String name_ar; ..//其他属性//.. public MyDate created_at; public MyDate updated_at; }

然后将json解析为Info类的数组列表。

List<Info> infoArray = new Gson().fromJson(stringJson, new TypeToken<List<Info>>(){}.getType());
