java - 将事件添加到 "Material-Calendar-View"插件的日历时出现问题

Question

我正在尝试从服务器获取 JSON 响应，然后解析它，并将一些日期事件添加到 Material-Calendar-View 插件的日历中。

它几乎可以工作，但是日历的日期装饰不是立即添加的，而是在滚动日历中的 View 页面之后添加的。

我有一个想法，我应该将所有代码放到另一个线程中，因为有一个异常

但我不确定是否应该这样做，如果应该的话，我也不知道如何做对。

public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        events = new ArrayList<>();
        calendarView = (CalendarView) getView().findViewById(R.id.calendarView);
        mRequestQueue = VolleySingleton.getInstance(getContext()).getRequestQueue();
        JSONParse();
        calendarView.setEvents(events);
    }
    private void JSONParse() {
        String url = "https://api.myjson.com/bins/14htbv";
        JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
                response -> {
                    try {
                        jsonArray = response.getJSONArray("info_stories");
                        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
                        for (int i = 0; i < jsonArray.length(); i++) {
                            JSONObject hit = jsonArray.getJSONObject(i);
                            String dateStr = hit.getString("date");
                            String text_main = hit.getString("text_main");

                            Date date = sdf.parse(dateStr);
                            Calendar cal = Calendar.getInstance();
                            cal.setTime(date);
                            events.add(new EventDay(cal, R.drawable.ic_home));
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    } catch (ParseException e) {
                        e.printStackTrace();
                    }
                }, error -> {
                    error.printStackTrace();
                });
        mRequestQueue.add(request);
    }
