将每周事件添加到日历

Question

我想向本机 Calendar 添加一个事件，这里我想在每个 Tuesday 上重复此事件，直到 31 December 2015:

btnWeekly.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {       
        Calendar calendar = Calendar.getInstance(); 

        Intent intent = new Intent(Intent.ACTION_INSERT)
                .setData(Events.CONTENT_URI)
                .setType("vnd.android.cursor.item/event")
                .putExtra(Events.TITLE, "Tuesdays")
                .putExtra(Events.DESCRIPTION, "Tuesday Specials")
                .putExtra(Events.EVENT_LOCATION, "Lixious Bench")
                .putExtra(Events.RRULE, "FREQ=WEEKLY;BYDAY=Tu;UNTIL=20151231")
                .putExtra(Events.DTSTART, calendar.getTimeInMillis())
                .putExtra(CalendarContract.EXTRA_EVENT_ALL_DAY, true)
                .putExtra(CalendarContract.Events.HAS_ALARM, 1)
                .putExtra(Events.AVAILABILITY, Events.AVAILABILITY_BUSY);
        startActivity(intent);
    }                               
}

问题： 在日历中它为每个 Thursday 显示此事件，而我在我的代码

中使用了“tu”

还有一件事，如果我还想为此事件提供持续时间，例如：仅 from 6:00 pm to 9:00 pm。

Answer 1

你说它显示星期四重复，但我得到的是星期四的开始日，每周二重复。所以我很确定 RRULE 部分是正确的。

我想你所要做的就是用日历设置实际的开始和结束时间以获得正确的毫秒数，然后用户 "beginTime" 而不是 "dtstart" 和 "endTime" 而不是"dtend".

@Override
public void onClick(View v) {

    // If you want the start times to show up, you have to set them
    Calendar calendar = Calendar.getInstance();

    // Here we set a start time of Tuesday the 17th, 6pm
    calendar.set(2015, Calendar.MARCH, 17, 18, 0, 0);
    calendar.setTimeZone(TimeZone.getDefault());

    long start = calendar.getTimeInMillis();
    // add three hours in milliseconds to get end time of 9pm
    long end = calendar.getTimeInMillis() + 3 * 60 * 60 * 1000;

    Intent intent = new Intent(Intent.ACTION_INSERT)
            .setData(Events.CONTENT_URI)
            .setType("vnd.android.cursor.item/event")
            .putExtra(Events.TITLE, "Tuesdays")
            .putExtra(Events.DESCRIPTION, "Tuesday Specials")
            .putExtra(Events.EVENT_LOCATION, "Lixious Bench")
            .putExtra(Events.RRULE, "FREQ=WEEKLY;BYDAY=TU;UNTIL=20150428")

            // to specify start time use "beginTime" instead of "dtstart"
            //.putExtra(Events.DTSTART, calendar.getTimeInMillis())
            .putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, start)
            .putExtra(CalendarContract.EXTRA_EVENT_END_TIME, end)

            // if you want to go from 6pm to 9pm, don't specify all day
            //.putExtra(CalendarContract.EXTRA_EVENT_ALL_DAY, true)
            .putExtra(CalendarContract.Events.HAS_ALARM, 1)
            .putExtra(Events.AVAILABILITY, Events.AVAILABILITY_BUSY);

    startActivity(intent);
 }

Answer 2

这里分享一个简单的代码希望对你有所帮助或指导：

Intent intentAlarm = new Intent(getActivity(), AlarmReceiver.class);

intentAlarm.putExtra("name", data.getName());
intentAlarm.putExtra("desc", data.getDescription());
intentAlarm.setData(Uri.parse("custom://" + data.getId()));
intentAlarm.setAction(String.valueOf(data.getId()));

// Create the AlarmManager
AlarmManager alarmManager = (AlarmManager) getActivity()
        .getSystemService(Context.ALARM_SERVICE);

// Set the alarm for a particular time
alarmManager.set(AlarmManager.RTC_WAKEUP, Calendar_Object
        .getTimeInMillis(), PendingIntent.getBroadcast(
                    getActivity(), Integer.parseInt(data.getId()), intentAlarm,
                    PendingIntent.FLAG_UPDATE_CURRENT));

Answer 3

对于星期二，首字母必须全部大写，即。 TU

.putExtra(CalendarContract.Events.RRULE, "FREQ=WEEKLY;BYDAY=TU;UNTIL=20151231")

要为您需要添加的事件指定持续时间

.putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME,getMillis(begintime))
.putExtra(CalendarContract.EXTRA_EVENT_END_TIME, getMillis(endtime))
