为什么在我添加了自定义事件的系统日历事件中将帐户显示为生日日历

Question

我尝试将事件从我的android日历应用同步到默认系统日历。事件已成功同步。但是活动帐户是生日日历。我需要将其更改为普通的电话帐户。可能吗？如果可能的话，我该怎么办？

ContentValues eventContentValue = new ContentValues();
eventContentValue.put(CalendarContract.Events.CALENDAR_ID, 2);
eventContentValue.put(CalendarContract.Events.TITLE, eventTitle);
eventContentValue.put(CalendarContract.Events.DESCRIPTION, "");
eventContentValue.put(CalendarContract.Events.EVENT_LOCATION, eventLocation);
if (stDateTime != null) {
    long startTime = stDateTime.getTime();// cal.getTimeInMillis();
    eventContentValue.put(CalendarContract.Events.DTSTART, startTime);
}
if (endDateTime != null) {
    long endTime = endDateTime.getTime();//cal.getTimeInMillis() + 60 * 60 * 1000;
    eventContentValue.put(CalendarContract.Events.DTEND, endTime);
}
eventContentValue.put(CalendarContract.Events.ALL_DAY, 0);
eventContentValue.put(CalendarContract.Events.STATUS, 1);// tentative 0, confirmed 1 canceled 2
eventContentValue.put(CalendarContract.Events.HAS_ALARM, 1);
eventContentValue.put(CalendarContract.Events.EVENT_TIMEZONE, TimeZone.getDefault().getID());
