闹钟仅在工作日重复

Question

Calendar calendar = Calendar.getInstance();

            calendar.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY); // Tue, Wed... 
            calendar.set(Calendar.HOUR_OF_DAY, 1);
            calendar.set(Calendar.MINUTE, 0);
            calendar.set(Calendar.SECOND, 0);
            PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context,MyClass.class),PendingIntent.FLAG_UPDATE_CURRENT);
            AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
            am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 7*24*60*60*1000, pi);

这将在星期一每周触发一次，但是：我想只在工作日（没有周六和周日）设置未决警报意图，如何只使用一个意图来做到这一点？我不想使用 5 个不同的 PendingIntents 和 5 个不同的 ID，因为这样我就必须取消 5

Answer 1

无法将日历设置为多个日期，因此您不能按照自己喜欢的方式进行设置。

我建议您每天重复闹钟并在 onReceive 中检查今天是哪一天，如果是 saturday/sunday 就立即 return 并且不要做任何事情。

Calendar calendar = Calendar.getInstance();

calendar.set(Calendar.HOUR_OF_DAY, 1);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context, MyClass.class), 0);
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 24 * 60 * 60 * 1000, pi);

接收方

public class MyClass extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (today == sunday || today == saturday) {
            return;
        }

        // do normal stuff.
    }
}

Answer 2

也许：

创建setAlarm方法：

public void setAlarm(long interval){ 
    Calendar calendar = Calendar.getInstance();

    //Alarm will go off at 1
    calendar.set(Calendar.HOUR_OF_DAY, 1);
    calendar.set(Calendar.MINUTE, 0);
    calendar.set(Calendar.SECOND, 0);

    PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context,MyClass.class),PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), interval, pi); 
}

创建cancelAlarm方法（可选，如果你想在某处使用它）：

public void cancelAlarm(Context context){
    PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context,MyClass.class),PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    am.cancel(pi);
}

检查您 onReceive()

中的日期

@Override
public void onReceive(Context context, Intent intent) {

    Calendar calendar = Calendar.getInstance();
    int day = calendar.get(Calendar.DAY_OF_WEEK); //Sunday = 1, Saterday = 7
    switch(day){

        case 6:  //Friday
            long interval = 3*24*60*60*1000 //skip saterday and sunday
            setAlarm(interval);

        case 2: //Monday
            setAlarm(AlarmManager.INTERVAL_DAY);  //Alarm will repeat everyday, until friday
        break;
}

PS: 不要忘记在第一次的某个地方设置闹钟，使用：setAlarm(AlarmManager.INTERVAL_DAY);

我认为这应该可行。

闹钟仅在工作日重复

Alarm repeating only on weekdays
