Question

我创建了一个重复规则为“FREQ = MONTHLY; BYMONTHDAY = 16; COUNT = 10”的事件。我在我的两个Android Calendars应用程序以及Google Calendar网站上看到了该活动。我可以从我的应用程序中读取所有其他事件，但我没有看到此事件。唯一的区别是这个事件有重复规则。这是我的阅读代码。

    public static MyEvents readCalendarMyEvent(Context context,Date date1, Date date2, int calendarID) 
{
    try
    {
            Calendar calendar1 = Calendar.getInstance();
            calendar1.setTime(date1);
            Calendar calendar2 = Calendar.getInstance();
            calendar2.setTime(date2);
            Uri l_eventUri;

            if (Build.VERSION.SDK_INT >= 8) {
                l_eventUri = Uri.parse("content://com.android.calendar/events");
            } else {
                l_eventUri = Uri.parse("content://calendar/events");
            }
            ContentResolver contentResolver = context.getContentResolver();
            String dtstart = "dtstart";
            String dtend = "dtend";

            String[] l_projection = new String[] { CalendarContract.Events.CALENDAR_ID,
                    CalendarContract.Events.TITLE, //1
                    CalendarContract.Events.DESCRIPTION,

问题解决了。我在where子句中犯了一个错误。

以下是正确的

        String where = "(" + dtstart + ">" 
                    + calendar1.getTimeInMillis() + " and "
                    + dtstart + "<" + calendar2.getTimeInMillis() + " and "+ 
                    CalendarContract.Events.CALENDAR_ID + " = '" + String.valueOf(calendarID) +"')";
