我从服务器收到了这个 Json 响应

我已经创建了这个对象

public class EventDetails {

@SerializedName("id")
public String id;

@SerializedName("title")
public String name;

@SerializedName("price")
public String price;    

@SerializedName("bookingFee")
public String booking_fee;

@SerializedName("standby")
public int isStandBy;

@SerializedName("subTitle")
public String show;

@SerializedName("closeTime")
public String time;

@SerializedName("openTime")
public String date;

@SerializedName("date")
public String eventDate;

//@SerializedName("genre")
public String[] genre;

@SerializedName("venueId")
public String venue_id;

@SerializedName("overview")
public String overview;

@SerializedName("djs")
public String presenter;

@SerializedName("terms")
public String terms;

@SerializedName("firstCutOff")
public String firstCutOff;

@SerializedName("secondCutOff")
public String secondCutOff;

@SerializedName("autoCutOff")
public String thirdCutOff;

@SerializedName("tickets")
public String tickets;

//@SerializedName("images")
public String[] image_url;

//@SerializedName("codes")
public String[] promoCodes; 
 }

我正在尝试使用 GSON 来解析它，就像我在其他项目中使用此代码所做的那样。

String result = httpRequest(params);
Type collectionType = new TypeToken<List<EventDetails>>(){}.getType();              
List<EventDetails> data = gson.fromJson(result, collectionType);

我不断收到此异常，不确定解决方案是什么

你有：

@SerializedName("terms")
public String terms;

你的 JSON 有：

"terms": {
    "ID Criteria": [
        "Photo ID",
        "Over 21s"
    ],
    "Dress Code criteria": [
        ""
    ]
},

“条款”不是String. 它是一个对象（特别是一个具有两个数组字段的对象），Gson 告诉你这一点。

为那些嵌套创建 Java 对象，然后添加到 EventDetails 类。

例如代码"codes": [ { "code": "HC0989", "price": "8.00" } ],

你可以创建一个类

public class Codes{
    public String code;
    public String price;
}

然后添加到您的 EventDetails

public Codes[] codes;
