java - JSONArray 无法转换为 JSONObject 异常

Question

我有一个按以下方式构造的 JSON 字符串，它会抛出异常，将其传递给 JSONArray timeJSONArray = new JSONArray(time);

这是错误 Value [{"daysByte":158,"from":1020,"to":1260},{"daysByte":96,"from":1020,"to":1320 }] at 0 of type org.json.JSONArray无法转换为JSONObject这就是我接收数组的方式，但我无法更改它，所以我在将其转换为JSON对象而不是JSON 字符串，这是它当前的格式。我做错了什么？

[   
   [  
      {  
         "daysByte":30,
         "from":660,
         "to":1290
      },
      {  
         "daysByte":96,
         "from":660,
         "to":1320
      },
      {  
         "daysByte":128,
         "from":1050,
         "to":1290
      }
   ],
   [  
      {  
         "daysByte":252,
         "from":690,
         "to":840
      },
      {  
         "daysByte":252,
         "from":1050,
         "to":1260
      }
   ]
]

这是我正在使用的代码。我正在获取以字符串形式传入的值

public ArrayList<String> getTimeList(String time){

        System.out.println("PLACES ACTIVITY " + time);
        ArrayList<String> times = new ArrayList<>();
        try{
            //JSONObject timeJSONObject = new JSONObject(time);
            JSONArray timeJSONArray = new JSONArray(time);
            ArrayList<LegacyTimeSpan> timeSpanList = new ArrayList<>();

            LegacyTimeSpanConverterImpl converter = new LegacyTimeSpanConverterImpl();


            for(int i = 0; i < timeJSONArray.length(); i++){

                int daysByte = timeJSONArray.getJSONObject(i).getInt("daysByte");
                int from = timeJSONArray.getJSONObject(i).getInt("from");
                int to = timeJSONArray.getJSONObject(i).getInt("to");

                System.out.println("TO " + to);

                LegacyTimeSpan timeSpan = new LegacyTimeSpan(daysByte, from, to);
                timeSpanList.add(timeSpan);

            }

            Log.d("Time span list", timeSpanList.toString());
            WeekSpan weekSpan = converter.convertToWeekSpan(timeSpanList);
            List<DayTimeSpanPair> dayTimeSpanPair = weekSpan.toDayTimeSpanPairs();
            for(int i = 0; i< dayTimeSpanPair.size(); i++){

                String timeRange = buildTimeString(dayTimeSpanPair.get(i));
                times.add(timeRange);


            }
        } catch(JSONException e){
            Log.d("PLACES EXCEPTION JSON",e.getMessage());
        }

        return times;
    }

This Code should work i think as u declare the json Format.

             [
                [
                  {
                  } ,{},{}             // Json Object Structure as u defined in you Question
topArray =      ],
                [  
                  {
                  },{},{}
                ]
             ]


for(JSONArray objArray : topArray){
    for(JSONObject eachObject : objArray){
   System.out.println(eachObject.get("daysByte"););
   System.out.println(eachObject.get("from");
   System.out.println(eachObject.get("to");
    }
}
