How to store JSON response in an array list?
提问by Veronika Gilbert
I want to store a JSON response in array list so that it will be easy to fetch data and assign it to other variables. This is my JSON response:
我想将 JSON 响应存储在数组列表中，以便轻松获取数据并将其分配给其他变量。这是我的 JSON 响应：
{
"statusCode":"1001",
"message":"Success",
"response":{
"holidays":[
{
"holidayId":78,
"year":2015,
"date":"2015-01-01",
"day":"Thrusday",
"occasion":"New Year Day",
},
{
"holidayId":79,
"year":2015,
"date":"2015-01-15",
"day":"Thrusday",
"occasion":"Pongal/Sankranthi",
},
{
"holidayId":80,
"year":2015,
"date":"2015-01-26",
"day":"Monday",
"occasion":"Republic Day",
}
],
"year":0
}
}
This is the way I am fetching data from the response:
这是我从响应中获取数据的方式：
JSONObject jobj = new JSONObject(result);
String statusCode = jobj.getString("statusCode");
if (statusCode.equalsIgnoreCase("1001"))
{
System.out.println("SUCCESS!");
String response = jobj.getString("response");
JSONObject obj = new JSONObject(response);
String holidays = obj.getString("holidays");
ArrayList<HolidayResponse> holidayResponse = holidays; //This stmt. shows me error
}
How do I solve this issue? Please help me.
我该如何解决这个问题？请帮我。

that is because of a JSON parse exception: the holidays is a JSON array.Hence the correct way would be:
那是因为 JSON 解析异常：假期是一个 JSON 数组。因此正确的方法是：
JSONObject obj = new JSONObject(response);
JSONArray holidays = obj.getJSONArray("holidays");
look hereto convert that to array list.
查看此处将其转换为数组列表。
