java需要BEGIN数组，但在第1行和第2行是BEGIN_对象

2 周 Questions & Answers 269

这是来自api的json数组数据/json对象数据，获取错误预期为begin_数组，但在第3行和第2列路径处为begin_对象$

    "offersdata": [
        {
            "offercode": "GRAB20",
            "title": "Get Upto",
            "description": "20% off on selected merchandise on purchase of INR 1000 or more"
        },
        {
            "offercode": "JAN20",
            "title": "Get Upto",
            "description": "20% Off on all purchases in January"
        },
        {
            "offercode": "BHHH",
            "title": "DES",
            "description": "FDSFS"
        }
    ],
    "message": "success"
}

界面

 @GET("user")
    Call<List<limitedoffers>>  getoffers();

    public String getDescription() {

    }

    public void setDescription(String description) {
        this.description = description;

啊，这是我最喜欢的话题

要解决这个问题，您必须实现serializer

对于您的情况，您必须自己将即将到来的对象转换为数组

# 2 楼答案

我已经完整地阅读了关于改型的内容，改型将在阵列完全序列化时起作用

；

 "offersdata": [
        {
            "offercode": "GRAB20",
            "title": "Get Upto",
            "description": "20% off on selected merchandise on purchase of INR 1000 or more"
        },
        {
            "offercode": "JAN20",
            "title": "Get Upto",
            "description": "20% Off on all purchases in January"
        },
        {
            "offercode": "BHHH",
            "title": "DES",
            "description": "FDSFS"
        }
    ],
    "message": "success"
}

在上面的Jsonarray中，offersdata具有ArrayList

在接口类中，必须更改此代码

@GET("user")
Call<List<limitedoffers>>  getoffers();

对这个

@GET("user")
Call<limitedoffers>  getoffers();

因为它不包含ArrayList

要在响应后从限制提供程序获取数组，只需使用

response.body().getOffersdata();

获取报价数据Arraylist

有 Java 编程相关的问题?
