To set repeat alarm for week days,use below code. Hope this is helpful.

        Calendar calender= Calendar.getInstance();

        calender.set(Calendar.DAY_OF_WEEK, weekNo);  //here pass week number
        calender.set(Calendar.HOUR_OF_DAY, hour);  //pass hour which you have select
        calender.set(Calendar.MINUTE, min);  //pass min which you have select
        calender.set(Calendar.SECOND, 0);
        calender.set(Calendar.MILLISECOND, 0);

        Calendar now = Calendar.getInstance();
        now.set(Calendar.SECOND, 0);
        now.set(Calendar.MILLISECOND, 0);

        if (calender.before(now)) {    //this condition is used for future reminder that means your reminder not fire for past time
            calender.add(Calendar.DATE, 7);
        }

        final int _id = (int) System.currentTimeMillis();  //this id is used to set multiple alarms

        Intent intent = new Intent(activity, YourServiceClass.class);

        PendingIntent pendingIntent = PendingIntent.getBroadcast(activity, _id, intent, PendingIntent.FLAG_UPDATE_CURRENT);

        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calender.getTimeInMillis(), 7 * 24 * 60 * 60 * 1000, pendingIntent);
