从JSON数组中提取数据
我知道它是一个数组,但是我对JSON完全陌生,需要帮助理解它的结构,这是我提取数据的尝试:
String JSonString = readURL("//my URL is here");JSONArray s = JSONArray.fromObject(JSonString);
JSONObject Data =(JSONObject)(s.getJSONObject(0));
System.out.println(Data.get("name"));
我拥有的JSON数据如下所示:
{"sports": [
{
"name": "basketball",
"id": 40,
"uid": "s:40",
"leagues": [
{
"name": "National Basketball Assoc.",
"abbreviation": "nba",
"id": 46,
"uid": "s:40~l:46",
"groupId": 7,
"shortName": "NBA",
"athletes": []
}
]
}
],
"resultsOffset": 10,
"resultsLimit": 10,
"resultsCount": 1,
"timestamp": "2013-11-18T03:15:43Z",
"status": "success"
}
我对这些东西的掌握并不强,因此感谢所有帮助。
回答:
这是个主意:
JSONObject root = new JSONObject(yourJsonString);JSONArray sportsArray = root.getJSONArray("sports");
// now get the first element:
JSONObject firstSport = sportsArray.getJSONObject(0);
// and details of the first element
String name = firstSport.getString("name"); // basketball
int id = firstSport.getInt("id"); // 40
JSONArray leaguesArray = firstSport.getJSONArray("leagues");
// and so on, you can process leaguesArray similarly
它应该可以工作(如果有编译错误,请随时投诉)
