android - 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);

这将在每周星期一触发一次，但是: 我想仅在工作日(不含周六和周日)设置挂起的警报 Intent ，如何仅使用一个 Intent 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 个

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，如果您想在某个地方使用它):

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 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:不要忘记第一次使用以下命令在某处设置闹钟:setAlarm(AlarmManager.INTERVAL_DAY);

我认为这应该可行。
