Próbuję utworzyć obiekt JSONObject zawierający tablicę innych obiektów JSON, które są zorganizowane przez łańcuch? na przykład chcę utworzyć obiekt JSONObject zawierający tablicę obiektów zawierających urządzenia, które są również zorganizowane według daty meczu

aby dać ci wizualne odniesienie do tego, co próbuję osiągnąć

JSONObject (JSONArray("Object 10/10/12" {(fixtures content)(fixtures content)}")
                     ("Object 11/10/12" {(fixtures content)(fixtures content)}"))

heres, co próbowałem do tej pory, ale po prostu nie mogę go uruchomić

        String matchDate1 = null;
        JSONArray datesArray = null;
        JSONObject fixturesInfo = null;
        JSONArray fixturesInfoArray = null;
        String matchDateTemp = null;

        for(int f = 0; f < fixturesArray.length(); f++){

            JSONObject matchDateDict = fixturesArray.getJSONObject(f);
            matchDate1 = matchDateDict.getString("matchdate");
            JSONArray fixturesInfoDict = fixturesInfo.getJSONArray(matchDate1);

           if(fixturesInfoDict == null){
               tempArray = null;
           } else {
               tempArray = fixturesInfoDict;
           }

           if(matchDateTemp != matchDate1){
              fixturesInfoArray.put(matchDate1);
           }

          matchDateTemp = matchDate1;

          tempArray.put(fixturesArray.getJSONObject(f));
          fixturesInfo.put(matchDate1, tempArray);

        }




            Log.v("MyFix", "fixturesInfo = " + fixturesInfo);

        }catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

heres paszy json
