從列表中檢索字符串

Question

我正在使用第三方庫在自定義日歷上顯示日期。

當用戶單擊一天時，我需要檢索一些信息。

這是onDayClick方法的代碼：

 public void onDayClick(Date dateClicked) {
                List<Event> events = compactCalendarView.getEvents(dateClicked);
                Log.d(TAG, "Day was clicked: " + dateClicked + " with events " + events);


            }

這是此方法的日志輸出：

Day was clicked: Wed Mar 13 00:00:00 GMT+01:00 2019 with events [Event{color=-16711936, timeInMillis=1552431600000, data=Some extra data that I want to store.}]

我想從該字符串中檢索字段數據...

根據CompactCalendarView庫，數據對象類型為Object 。 因此，要檢索該字段，只需遍歷事件列表，然后訪問數據字段即可：

List<Event> events = compactCalendarView.getEvents(dateClicked);
for (Event event : events) {
    Object data = event.getData();
    // Access to other event properties
    int color = event.getColor();
    long timeInMillis = event.getTimeInMillis();
}
