推荐答案

我不知道你是怎么想它进行排序，如何完整的数据看起来像，但这里的想法：

I don't know how you want it to be sorted and how your full data looks like but here's the idea:

JSONArray jsonEvents = new JSONObject(json).getJSONArray("event");
JSONObject [] events = new JSONObject[jsonEvents.length()];

// fill an array with your events
for (int i = 0; jsonEvents.length(); i++) {
    events[i] = jsonEvents.getJSONObject(i);
}

// sort them
Arrays.sort(events, new Comparator<JSONObject>() {
    static final SimpleDateFormat sdfToDate = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");

    public int compare(JSONObject event1, JSONObject event2) {
        return sdfToDate.parse(event1.getString("startTime")).compareTo(
            sdfToDate.parse(event2.getString("startTime"))
    }
});
