java - 设置多个闹钟

Question

到目前为止，我有这个方法可以设置重复闹钟。该闹钟在上午 11 点 15 分每隔 15 分钟设置一次闹钟。我想知道是否想在该闹钟旁边设置另一个凌晨 12:00 的重复闹钟，我需要做任何不同的事情吗？

另外，当闹钟响起时是否可以显示多种 View ？如果我希望在上午 11:15 弹出一个 View ，并在中午 12:36 弹出另一个 View ，我可以设置吗？如果是这样，怎么办？

private void setCollectionAlarms() {

    AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(context, AlarmReceiver.class);
    pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);

    interval = 900000;

    try {
        //If the date is set to HHmm, then add current date time
        SimpleDateFormat format = new SimpleDateFormat("HH:mm");
        String time = "11:15";

        long timeOfFirstCollectionInMillis = format.parse(time).getTime();
        System.out.println("Time in Milis: " + timeOfFirstCollectionInMillis);

        Calendar now = Calendar.getInstance();
        now.setTime(new Date());

        Calendar cal = Calendar.getInstance();
        Date timedate = format.parse(time);
        cal.setTime(timedate); // thinks 1970
        cal.set(Calendar.YEAR, now.get(Calendar.YEAR));
        cal.set(Calendar.MONTH, now.get(Calendar.MONTH));
        cal.set(Calendar.DAY_OF_MONTH, now.get(Calendar.DAY_OF_MONTH));

        //If the time from the db is before now (That is no date set but time set), then set it for tomorrow
        if (cal.before(now)) {
            // increase
            Date tomorrow = cal.getTime();
            cal.setTime(tomorrow);
            cal.add(Calendar.DATE, 1);
            tomorrow = cal.getTime();
            System.out.println("TimeDate for Tomorrow: " + tomorrow);

            //convert date to milis
            long timeInMilis = (tomorrow.getTime());

            //Set Alarm to Repeat
            manager.setRepeating(AlarmManager.RTC_WAKEUP, timeInMilis, interval, pendingIntent);


            //else, set the alarm for today
        } else {
            timedate = cal.getTime();
            System.out.println("TimeDate: " + timedate);

            //convert date to milis
            long timeInMilis = (timedate.getTime());

            //Set Alarm to Repeat
            manager.setRepeating(AlarmManager.RTC_WAKEUP, timeInMilis, interval, pendingIntent);


        }
    } catch (ParseException e) {
        e.printStackTrace();
    }

}

我刚刚写完一篇关于这个主题的博客文章。您需要处理触发警报时要做的所有逻辑以及扩展 BroadcastReceiver 的类中的代码运行。

Android bytes: Alarms

希望这足够清楚，但如果您还有其他问题，我可以更新答案。
