java - 以正确的顺序获取 JSONObject

Question

我正在使用 org.json 库并尝试以如下所示的简单形式创建 JSON 对象 stops 但我总是得到所有 timeEntries 在同一个 JSONArray timeArray 中，并且名称总是在 current output

中改变

当前输出:

{"arrival_time":
                {"mon-fri":[
                               ["04:48","05:18","05:46","06:16"],
                               ["04:52","05:22","05:50","06:20"],
                               ["04:57","05:27","05:56","06:26"]
                           ]
                },
"stops_name":"third name"}

代码:

    ArrayList<String> result = new ArrayList<String>();
    JSONObject stops = new JSONObject();
    JSONObject arrivals = new JSONObject();
    JSONArray arrivalMoFr  = new JSONArray();

    for (Entry<String, List<String>> entry : map.entrySet()) {
        String name = entry.getKey();
        List<String> timeEntries = entry.getValue();                        
        try {                       
        stops.put("stops_name", name);

        JSONArray timeArray = new JSONArray(timeEntries);
        arrivalMoFr.put( timeArray);

        arrivals.put("mon-fri", arrivalMoFr);

        stops.put("arrival_time", arrivals);

        System.out.println(stops.toString(3));
        } catch (JSONException e) {
            e.printStackTrace();
        }

简单的结果应该怎么样

{"arrival_time":
                {"mon-fri":["04:48","05:18","05:46","06:16"]

                }
"stops_name":"first name"},
{"arrival_time":
                {"mon-fri":["04:52","05:22","05:50","06:20"]

                }
"stops_name":"second name"},
{"arrival_time":
                {"mon-fri":["04:57","05:27", "05:56","06:26"]

                }
"stops_name":"third name"}

请记住，您需要一个数组 作为您的根对象。您必须多次创建其他数组和对象，因此在 for 循环之外初始化它们没有用。

ArrayList<String> result = new ArrayList<String>();
JSONArray stops = new JSONArray();

for (Entry<String, List<String>> entry : map.entrySet()) {
    String name = entry.getKey();
    List<String> timeEntries = entry.getValue();                        
    try {
        JSONObject stop = new JSONObject();                     
        stop.put("stops_name", name);

        JSONArray timeArray = new JSONArray(timeEntries);
        //arrivalMoFr.put( timeArray);

        JSONObject arrivals = new JSONObject();
        arrivals.put("mon-fri", timeArray);

        stop.put("arrival_time", arrivals);
        stops.put(stop);

        //System.out.println(stops.toString(3));
    } catch (JSONException e) {
        e.printStackTrace();
    }
}
