Android重复报警管理器呼叫接收器无限次

Question

我每24小时在重复模式下设置一个闹钟。因此，警报接收器应该只在一次设置的时间内调用，但它会重复调用。为什么呢？

这是我附上我的代码来设置闹钟：

        AlarmManager alarmMgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        Intent objIntent = new Intent(this, PedometerAlarmReciever.class);
        PendingIntent alarmIntent = PendingIntent.getBroadcast(this, 0, objIntent, 0);

        // Set the alarm to start at 21:32 PM
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        calendar.set(Calendar.HOUR, 11);
        calendar.set(Calendar.MINUTE, 20);
        calendar.set(Calendar.AM_PM, Calendar.AM);

        // setRepeating() lets you specify a precise custom interval--in this case,
        // 1 day
        alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
                AlarmManager.INTERVAL_DAY, alarmIntent);
