当我将json转换为Gson对象预期为BEGIN_ARRAY但为BEGIN_OBJECT时，会发生Gson错误

Question

当我将json转换为gson时，我得到了以下错误：

E/AndroidRuntime(1142):com.google.gson.jsonSyntaxException:java.lang.IllegalStateException:预期为BEGIN_ARRAY，但BEGIN_OBJECT位于第1行第51列

  {

"ResultCode": "0",
"ErrorMessage": null,
"Payload": [
    {
        "Items": [
            {
                "Title": "Star Wars"
            },
            { … },
            { … },
            { … },
            { … },
            { … },
            { … },
            { … },
            { … },
            { … },
            { … }
        ]
    },
    {
        "Items": [ … ]
    },
    {
        "Items": [ … ]
    }
]

} 

 import java.util.List;

 public class MResult{
private String ErrorMessage;   
private String ResultCode;
private List<List<Item>> Payload;

public String getErrorMessage() {
    return ErrorMessage;
}
public void setErrorMessage(String errorMessage) {
    ErrorMessage = errorMessage;
}
public String getResultCode() {
    return ResultCode;
}
public void setResultCode(String resultCode) {
    ResultCode = resultCode;
}
public List<List<Item>> getPayload() {
    return Payload;
}
public void setPayload(List<List<Item>> payload) {
    Payload = payload;
}

}

 public class Item{

private String Title;

 public String getTitle() {
    return Title;
}
public void setTitle(String title) {
    Title = title;
}

 }

 MResult serviceResult = new Gson().fromJson(result,MResult.class);

Answer 1

您需要另一个类来保存项

List<Foo> Payload;

class Foo{
   List<Item> Items;
}
