获取NumberFormatException：无效的双精度：“”

Question

将数据附加到我的arrayList时出现此错误。

这是我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" ] 
    } 
] 

我附上上述响应，

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

我在我的代码

和错误notusing任何双重价值在

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

越来越

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>(); 

请帮我走出这个问题

Answer 1

1）尽量到您的AllUserMessages类Latitude, Longitude变量类型的double更改为String

2），或改变Latitude, Longitude服务器网站翻番。
