每天两次使用alarmmanager？ [英] How to use alarmmanager 2 times every day?

问题描述

我已经使用以下代码每天设置一次警报管理器，我希望设置2个不同的时间，因此每天设置2次。

I have used the following code to set alarmmanager for only one time every days, I'd like to have 2 different time to set, so 2 times every days.

我的代码：

Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 10);
calendar.set(Calendar.MINUTE, 35);
calendar.set(Calendar.SECOND, 0);    AlarmManager am = (AlarmManager)     getApplicationContext().getSystemService  (Context.ALARM_SERVICE);
PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(getApplicationContext(),     AlarmReceiver.class),      PendingIntent.FLAG_UPDATE_CURRENT);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),     AlarmManager.INTERVAL_DAY, pi);

推荐答案

您可以使用AlarmManager.INTERVAL_DAY / 2间隔：

You can use an interval of AlarmManager.INTERVAL_DAY / 2 :

Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 10);
calendar.set(Calendar.MINUTE, 35);
 calendar.set(Calendar.SECOND, 0);    
AlarmManager am = (AlarmManager)getApplicationContext().getSystemService  (Context.ALARM_SERVICE);
Intent intent = new Intent(getApplicationContext(), AlarmReceiver.class);
 PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), 0, intent,      PendingIntent.FLAG_UPDATE_CURRENT);
 am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),        AlarmManager.INTERVAL_DAY / 2, pi);

但是如果您触发闹钟的时间很重要，则可以使用两个日历对象：

but if the time of the day in which you fire your alarm matters you can use two calendar objects :

Calendar cal1 = Calendar.getInstance();
cal1.set(Calendar.HOUR_OF_DAY, 12); //midday
cal1.set(Calendar.MINUTE, 00);
cal1.set(Calendar.SECOND, 00);

Calendar cal2 = Calendar.getInstance();
cal2.set(Calendar.HOUR_OF_DAY, 18);//8pm for example
cal2.set(Calendar.MINUTE, 00);
cal2.set(Calendar.SECOND, 00);

并设置您的警报管理器：

and set your alarm manager :

am.setRepeating(AlarmManager.RTC_WAKEUP, cal1.getTimeInMillis(),cal2.getTimeInMillis(), pi);
