如何解析Android中的json字符串？

Question

可能重复:
Android/Java中的JSON数组迭代

我从服务器获取JSON字符串,我已经通过代码获得了JSON字符串.但我不明白如何解析它.

下面是我的JSON字符串

{
    "university": {
        "name": "oxford",
        "url": "http://www.youtube.com"
    },
    "1": {
        "id": "2",
        "title": "Baseball",
        "datetime": "2011-11-11 10:41:46"
    },
    "2": {
        "id": "1",
        "title": "Two basketball team players earn all state honors",
        "datetime": "2011-11-11 10:40:57"
    }
}

请提供任何指导或代码段.

Answer 1

使用JSON类进行解析,例如

JSONObject mainObject = new JSONObject(Your_Sring_data);
JSONObject uniObject = mainObject.getJSONObject("university");
String  uniName = uniObject.getString("name");
String uniURL = uniObject.getString("url");

JSONObject oneObject = mainObject.getJSONObject("1");
String id = oneObject.getString("id");
....

另外根据你的json字符串代码片段必须是这样的: -

JSONObject mainObject = new JSONObject(yourstring);

JSONObject universityObject = mainObject.getJSONObject("university");
JSONString name = universityObject.getString("name");  
JSONString url = universityObject.getString("url");

其他对象也一样.
