如何从另一个班级

Question

我正在开发一个包含Spinner的应用程序。我希望它：检测依赖于Spinner的int更改，如果此值=不为0，则需要创建一个String并使用int值对其进行实例化。

这是Hider.class代码:(服务）

public int NOTIF_ID =1;
public double timeup;
public static  String time;
public IBinder onBind(Intent intent)
{
    return null;
}

@Override
public int onStartCommand(Intent argument, int flags, int startId)
{

    Toast.makeText(getApplicationContext(),"Service Started", Toast.LENGTH_SHORT).show();
     NotificationManager notif_manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);

    Notification.Builder notif_specs = new Notification.Builder(this);
    notif_specs.setContentTitle("Notification");
    notif_specs.setContentText("is now active..."+ timeup);
    notif_specs.setSmallIcon(R.drawable.combo);
    notif_specs.setTicker("Bildirim Geldi");
    notif_specs.setOngoing(true);

    Intent intent = new Intent(this, MainActivity.class);
    PendingIntent bildirimin_niyeti = PendingIntent.getActivity(this, NOTIF_ID, intent, 0);
    notif_specs.setContentIntent(bildirimin_niyeti);

    final Notification notif = notif_specs.getNotification();

    notif_manager.notify(NOTIF_ID, notif);



    if (MainActivity.timer_time!=0)
    {
        String str;
        switch (MainActivity.timer_time)
        {
            case 1: str = "Remaining 1m";
                            break;
            case 5: str = "Remaining 5m";
                            break;
            case 10: str = "Remaining 10m";
                            break;
        }

    }


    return START_STICKY; 
}

public void onDestroy()
{
    NotificationManager notif_mani = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
    notif_mani.cancel(NOTIF_ID);

    if(MainActivity.vib_bool)

    {
        final MediaPlayer oynatıcı = MediaPlayer.create(this, R.drawable.end);
        oynatıcı.start();
    }


    Toast.makeText(getApplicationContext(),"Service Stopped",Toast.LENGTH_SHORT).show();

    super.onDestroy();

}


}

这段代码不工作导致OnStartCommand（）工作一次我想。那么如何编写这段代码来重复运行呢？ 谢谢你的帮助。
