按星期几过滤通知

Question

我的闹钟和通知有问题。我设置了当地到达acerta的通知，并且没有问题。我试图让用户选择在设置中使用共享首选项获取通知的日期，并按照您在代码中看到的那样获取它们。但这不起作用，即使我决定有一天还有所有其他通知没有区别，也无法弄清楚是什么错。有人能帮我吗？谢谢大家。

我必须刷新警报吗？

 SharedPreferences sharedPrefs = getSharedPreferences("SETTING_NOTIFICATION", MODE_PRIVATE);

     calendar = Calendar.getInstance();
    if (sharedPrefs.getBoolean("lun", true)){
        calendar.set(Calendar.DAY_OF_WEEK, 0);
        calendar.set(Calendar.HOUR_OF_DAY, 18);
        calendar.set(Calendar.MINUTE, 5);
        calendar.set(Calendar.SECOND, 0);
        notifi();
        Toast.makeText(getApplicationContext(), "notification lunedi", Toast.LENGTH_LONG).show();
    }
    if (sharedPrefs.getBoolean("mar", true)){
        calendar.set(Calendar.DAY_OF_WEEK, 1);
        calendar.set(Calendar.HOUR_OF_DAY, 18);
        calendar.set(Calendar.MINUTE, 5);
        calendar.set(Calendar.SECOND, 0);
        notifi();
    }
    if (sharedPrefs.getBoolean("mer", true)){
        calendar.set(Calendar.DAY_OF_WEEK, 2);
        calendar.set(Calendar.HOUR_OF_DAY, 18);
        calendar.set(Calendar.MINUTE, 5);
        calendar.set(Calendar.SECOND, 0);
        notifi();
    }
    if (sharedPrefs.getBoolean("gio", true)){
        calendar.set(Calendar.DAY_OF_WEEK, 3);
        calendar.set(Calendar.HOUR_OF_DAY, 18);
        calendar.set(Calendar.MINUTE, 5);
        calendar.set(Calendar.SECOND, 0);
        notifi();
    }
    if (sharedPrefs.getBoolean("ven", true)){
        calendar.set(Calendar.DAY_OF_WEEK, 4);
        calendar.set(Calendar.HOUR_OF_DAY, 18);
        calendar.set(Calendar.MINUTE, 5);
        calendar.set(Calendar.SECOND, 0);
        notifi();
    }
    if (sharedPrefs.getBoolean("sab", true)){
        calendar.set(Calendar.DAY_OF_WEEK, 5);
        calendar.set(Calendar.HOUR_OF_DAY, 18);
        calendar.set(Calendar.MINUTE, 5);
        calendar.set(Calendar.SECOND, 0);
        notifi();
    }
    if (sharedPrefs.getBoolean("dom", true)){
        calendar.set(Calendar.DAY_OF_WEEK, 6);
        calendar.set(Calendar.HOUR_OF_DAY, 18);
        calendar.set(Calendar.MINUTE, 5);
        calendar.set(Calendar.SECOND, 0);
        notifi();
    }

}


public void notifi(){
    Intent intent1 = new Intent(Home.this, AlarmReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(Home.this, 0,intent1, PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager am = (AlarmManager) Home.this.getSystemService(Home.this.ALARM_SERVICE);
    am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
