Android Kotlin-java.lang.IllegalStateExpection:应为BEGIN_数组，但为字符串

我面临着这个问题。我在互联网上搜索过，但答案是Java，而不是Kotlin。我如何解决这个问题？如果你还需要什么，请告诉我。我正试图找到最近的餐馆，以确定用户位置。目前我正在使用静态变量，因为我还无法获得Zomato APi。我怎样才能做到这一点？我开始学习kotlin已经4-5天了

我的餐厅数据类

data class Restaurant(
    @SerializedName("name")
    val restName: String?,
    @SerializedName("address")
    val restAddress: String?
)

我的API接口

interface ZomatoAPI {

    @Headers(
        "Accept: application/json",
        "user-key: $API_KEY"
    )
    @GET("/search")
    fun getRestaurants(@Query("count") count: Int
                       ,@Query("lat") latitude: Double
                       ,@Query("lon") longitude: Double
                        ,@Query("sort") sort : String
                        ,@Query("order") order : String

    ): Single<List<Restaurant>>

}

---

您的

getRestaurants

方法应该如下所示：

interface ZomatoAPI {

@Headers(
    "Accept: application/json",
    "user-key: $API_KEY"
)
@GET("/search")
fun getRestaurants(@Query("count") count: Int
                   ,@Query("lat") latitude: Double
                   ,@Query("lon") longitude: Double
                    ,@Query("sort") sort : String
                    ,@Query("order") order : String

): Single<RestaurantResponse>

接口ZomatoAPI{
@标题(
“接受：应用程序/json”，
“用户密钥：$API_密钥”
)
@获取（“/search”）
趣味餐厅（@Query（“count”）count:Int
，@Query（“纬度”）纬度：双
，@Query（“lon”）经度：双精度
，@Query（“sort”）排序：字符串
，@Query（“订单”）订单：字符串
)：单身

}

你的模型课应该是这样的

data class RestaurantResponse(
    @SerializedName("restaurants")
    val restaurants: List<Restaurant>?,
    @SerializedName("results_found")
    val results_found: Int?
    @SerializedName("results_start")
    val results_start: Int?
    @SerializedName("results_shown")
    val results_shown: Int?
)

数据类餐厅响应(
@序列化名称（“餐厅”）
瓦尔餐厅：名单？，
@SerializedName（“找到的结果”）
找到的val结果：Int？
@SerializedName（“结果和开始”）
val结果\u开始：Int？
@SerializedName（“显示结果”）
显示的val结果：Int？
)

您需要共享堆栈跟踪、看到此错误的行以及能够重现错误的最小代码issue@sidgate当我启动它时，通常没有错误，但也没有加载。在我的ListViewModel中有onSuccess和onError函数，我在这两个函数上都设置了一个断点，它会给出错误消息。“在第1行第1列路径$”错误表示这是解析响应时产生的问题。您可以添加响应的样本格式或自己检查。可能您的响应JSON有缺陷，错误是这样说的。您需要为响应创建整个类（带有子类）。我建议您将json（来自zomato api）传递到此页面并生成必要的类@MihodiLushan我将立即添加它以获得回复，但我的适配器和listview是否应使用RestaurantResponse或Listenery其他内容应与之前相同。请记住，您之前期望的是列表，现在列表位于模型类中。您应该在从响应对象获取后传递列表。我尝试了jsonschema2pojo.org并进行了工作，我需要获取所有详细信息，但只是想学习如何使用APi获取公正的名称。非常感谢您的帮助@三河山
