如何在不知道名稱的情況下解析JSONObject？

Question

我有這樣的json字符串：

 { "2":{ "id":"2", "first":"3", "last":"2", "ilike":"1", "created_at":"2015-06-30 16:57:39", "liketo":"2", "firstname":"FirstName", "lastname":"LastName", "birthday":null } } 

如何在不知道名稱“ 2”而僅移至下一個數組的情況下解析JSONObject？

Answer 1

String json="" // place your json format here in double Quotes with proper escapes .......
jObject = new JSONObject(json.trim());
Iterator<?> keys = jObject.keys();

while( keys.hasNext() ) {
    String key = (String)keys.next();
    if ( jObject.get(key) instanceof JSONObject ) {
         // do what ever you want with the JSONObject.....
    }
}
