获取数字格式异常： 无效双精度： " "

Question

在将数据附加到我的arraylist时获取此错误。

这是我的jsonresponse

[
    {
        "ChatId": 13,
        "Name": [],
        "LoginUserId": "123xc-xcv4r4",
        "Message": [
            {
                "message": "Message 1 ",
                "Status": 0,
                "Date": "2017-09-11T12:56:21.07",
                "Name": "name",
                "UserId": "12",
                "Id": 0,
                "Latitude": "",
                "Longitude": ""
            },
        ],
        "UserId": ["3434scjdcndne4r4ir" ]
    }
]

我以上响应为

     Type type = new TypeToken<List<jsonModel>>() {
                    }.getType();
   arraylist= Conversions.getGson().fromJson(response, type);

我在我的代码中没有任何双重值

和错误正在

 arraylist= Conversions.getGson().fromJson(response, type);

这是我的pojo类

private int ChatId;
    private ArrayList<String> Name = new ArrayList<String>();
    private String LoginUserId;
    private ArrayList<AllUserMessages> Message = new 
    ArrayList<AllUserMessages>();
    private ArrayList<String> UserId = new ArrayList<String>();

请帮助我摆脱这个问题

Answer 1

1）尝试将您的AllUserMessages类Latitude, Longitude变量类型double更改为String

2）或将Latitude, Longitude从服务器站点更改为双重。
