These questions talk about the same thing as you want. Those answers will be helpful:

You just need to specify the day to start it and then repeat it every 7 days. There are few ways specified in answers on given questions:

Update:

In your comment you said

How to set the triggerAtMillis part in setRepeating. say for example today is Tuesday, I choose weekly Monday, Wednesday, Friday. - What do I put for Wednesday ?

What I understood that that if today is Tuesday, how to set alarm for lets say Wednesday repeating, right? First of all yes you can use mulltiple id's to set alarms for each day separately.

Then you can add alarmCalendar.set(Calendar.DAY_OF_WEEK, week); line to your existing code. Based on the week day( from 1-7) it repeats for that day. You can pass it into a function as parameter. Like:

    setAlarm(2); //set the alarm for this day of the week

    public void setAlarm(int dayOfWeek) {
        // Add this day of the week line to your existing code
        alarmCalendar.set(Calendar.DAY_OF_WEEK, dayOfWeek);

        alarmCalendar.set(Calendar.HOUR, AlarmHrsInInt);
        alarmCalendar.set(Calendar.MINUTE, AlarmMinsInInt);
        alarmCalendar.set(Calendar.SECOND, 0);
        alarmCalendar.set(Calendar.AM_PM, amorpm);

        Long alarmTime = alarmCalendar.getTimeInMillis();
        //Also change the time to 24 hours.
        am.setRepeating(AlarmManager.RTC_WAKEUP, alarmTime, 24 * 60 * 60 * 1000 , pi); 
}

I've taken the example from one of above question. Hope its more clear now.
