如何获取JSONObject的元素？

JSonObject json = new JSonObject(yourdata);String statistics = json.getString("statistics");JSonObject name1 = json.getJSonObject("John");String ageJohn = name1.getString("Age");

为了以动态方式获取这些项目：

JSonObject json = new JSonObject(yourdata);String statistics = json.getString("statistics");for (Iterator key=json.keys();key.hasNext();) {    JSonObject name = json.get(key.next());    //now name contains the firstname, and so on... }
