我已经完整阅读了Retrofit，Retrofit将在数组完美序列化时起作用。

 "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 offersdata 中有 ArrayList

在接口(interface)类中必须更改代码

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

到此

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

因为它不包含ArrayList

要在响应后从Limitedoffers获取数组，只需使用

response.body().getOffersdata();

获取offersdata数组列表
