java - 一段时间后通知

Question

我想添加一个通知管理器，它应该在几毫秒后启动。 一切都在运行，但我仍然不知道如何添加几周后通知的时间？

public void test(){
    int icon = R.drawable.ic_launcher;
    CharSequence ticker ="ticker";
    long showAt =System.currentTimeMillis();
    Notification notification = new Notification(icon, ticker, showAt);activity/intent
    CharSequence notificationTitle = "test";
    CharSequence notificationMessage = "Test1";
    Intent intent = new Intent(this, Activity.class);
    PendingIntent objPendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
    Context ctx = getApplicationContext();
    notification.setLatestEventInfo(ctx, notificationTitle, notificationMessage, objPendingIntent);
    final int notificationIdentifier = 101; //an unique number set by developer to identify a notification, using this notification can be updated/replaced
    NotificationManager notificationManager = (NotificationManager)
            getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(notificationIdentifier, notification);
    // ... 
}

您需要使用Alarm manager带有在固定时间间隔后重复通知的通知。检查AlarmManagerNotificationManagerTutorial , Android AlarmManager tutorial和 Multiple Notifications Using AlarmManager 。那里有很多教程。希望这可以帮助。
