Alarm Manager的参考资料说

马上。

我在申请时遇到了这个问题。这是我的报警管理器代码:

Intent myIntent = new Intent(getActivity(), DinnerAlarmReceiver.class);
                pendingDinnerIntent = PendingIntent.getBroadcast(getActivity(), 0, myIntent, 0);

                Calendar calendar = Calendar.getInstance();
                calendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
                calendar.set(Calendar.MINUTE, minute);

                alarmManager.set(AlarmManager.RTC_WAKEUP,
                        calendar.getTimeInMillis(), pendingDinnerIntent);

-----编辑------

Calendar calendar = Calendar.getInstance();
                long currentTime = calendar.getTimeInMillis();
                calendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
                calendar.set(Calendar.MINUTE, minute);
                long setTime = calendar.getTimeInMillis();
                Timestamp setTimestamp = new Timestamp(setTime);
                Timestamp currentTimestamp = new Timestamp(currentTime);
                if (setTimestamp.after(currentTimestamp))
                {
                    alarmManager.set(AlarmManager.RTC_WAKEUP,
                            calendar.getTimeInMillis(), pendingDinnerIntent);
                }
                else
                {
                }

我该怎么办 alarmManager setTimestamp currentTimestamp

你不需要创造 Timestamp s、你可以用你的手来做 Calendar

Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
calendar.set(Calendar.MINUTE, minute);

if(calendar.before(Calendar.getInstance())) {
    calendar.add(Calendar.DATE, 1);
}

alarmManager.set(AlarmManager.RTC_WAKEUP,
    calendar.getTimeInMillis(), pendingDinnerIntent);

我还想提到的是,在基特卡特,如果你的 targetSdkVersion 19岁或以上 AlarmManager#set() setExact*() 方法。
