安卓 : Showing wrong end date (one day before of actual date) in Google Calendar while adding an event with intent

Question

我在向 Google 日历添加事件时遇到问题，因为它在 Google 日历屏幕中显示错误的结束日期但是如果您添加该事件，它将生成一个具有正确结束日期的事件。不确定为什么它显示结束日期前 1 天。

例如，如果结束日期是 8 月 31 日，它将在日历预览屏幕上显示为 8 月 30 日，但仅为 8 月 31 日生成事件。

List<String> dateFormats = Arrays.asList(CALENDER_EVENT_DATE_FORMAT_1,
                CALENDER_EVENT_DATE_FORMAT_2);

        Calendar calStartDate = Calendar.getInstance();
        Calendar calEndDate = Calendar.getInstance();
        Date eventStartDate = null;
        Date eventEndDate = null;
        for (String format : dateFormats) {
            SimpleDateFormat sdf = new SimpleDateFormat(format);
            try {
                eventStartDate = sdf.parse(startDate);
                eventEndDate = sdf.parse(endDate);
            } catch (ParseException e) {

            }
        }

        Intent intent = new Intent(Intent.ACTION_EDIT);
        intent.setType(CALENDER_EVENT_TYPE);
        intent.putExtra(CALENDER_EVENT_TITLE, title);
        intent.putExtra(CALENDER_EVENT_DESC, note);
        intent.putExtra(CalendarContract.EXTRA_EVENT_ALL_DAY, isAllDay);

        calStartDate.set(Calendar.HOUR_OF_DAY, 0);            // set hour to midnight
        calStartDate.set(Calendar.MINUTE, 0);                 // set minute in hour
        calStartDate.set(Calendar.SECOND, 0);                 // set second in minute
        calStartDate.set(Calendar.MILLISECOND, 0);            // set millisecond in second
        calStartDate.setTime(eventStartDate);

        calEndDate.set(Calendar.HOUR_OF_DAY, 0);            // set hour to midnight
        calEndDate.set(Calendar.MINUTE, 0);                 // set minute in hour
        calEndDate.set(Calendar.SECOND, 0);                 // set second in minute
        calEndDate.set(Calendar.MILLISECOND, 0);            // set millisecond in second
        calEndDate.setTime(eventEndDate);

        intent.putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME,
                calStartDate.getTimeInMillis());
        intent.putExtra(CalendarContract.EXTRA_EVENT_END_TIME,
                calEndDate.getTimeInMillis());

        weakActivity.get().startActivity(intent);

这可能有帮助:

写入事件

如果 allDay 设置为 1，eventTimezone 必须是 Time.TIMEZONE_UTC 并且时间必须对应于午夜边界。
