尝试使用 Retrofit 解析 JSON 响应时出现以下错误： java.lang.IllegalStateException: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $

这是 JSON 响应的样子：

                }
            }]
        }
    }]
}

这是我的经销商课程：

public class Dealer {
    @SerializedName("Id")
    String mId;

    @SerializedName("Name")
    String mName;

    @SerializedName("Region")
    String mRegion;

    @SerializedName("UniqueKey")
    String mUniqueKey;

    public String getId() {
        return mId;
    }

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

    public String getName() {
        return mName;
    }

    public void setName(String name) {
        this.mName = name;
    }

    public String getRegion() {
        return mRegion;
    }

    public void setRegion(String region) {
        this.mRegion = region;
    }

    public String getUniqueKey() {
        return mUniqueKey;
    }

    public void setUniqueKey(String uniqueKey) {
        this.mUniqueKey = uniqueKey;
    }
}

这是改造电话：

@FormUrlEncoded
@POST("get_dealer_list.php")
Call<List<Dealer>> getDealers(@Field("listname") String listName, @Field("outputformat") String outputFormat);

关于我做错了什么的任何想法？

  1. 创建以下类：

对于最小的孩子

"@attributes": { "Id": "12", "Name": "Barons Tokai", "Region": "Western Cape", "Status": "active", "UniqueKey": "96ec67999ed613174efe17f697dc4695" }

    public class DealerObject {
       @SerializedName("@attribute")
       Dealer attribute;

       public getAttribute() {
          return attribute;
       }
    }

   public class BigDealerObject {

       List<DealerListObject> Dealers;

       public getBigDealerObject {
          return Dealers;
       }
    }

然后对于所有响应：

   public class DealerResponse {

       List<BigDealerObject> automobi;

       public getAutomobi {
          return automobi;
       }
    }

最后，调用：

Call<DealerResponse> getDealers(@Field("listname") String listName, @Field("outputformat") String outputFormat);

当然。如您所见，您的 JSON 响应以对象 ({}) 开头，而您尝试将其分配给列表 (List)。为了解决这个问题，您应该创建一个名为 Response 的类，其中包含以下字段和类：

public class Response {
    public DealersClass Dealers;
}

class DealersClass {
    public List<Dealer> Dealer;
}

Dealer 类是您构建的类。将来避免此类错误的一种简单方法是查看您的回复。当您看到 { 时，这意味着您应该将其与 Java 类匹配。当你看到 [ 这意味着你应该将它与一个 Java 列表相匹配。

希望能帮助到你。
