安卓通知时间

Question

我有一个公共(public)类来发出通知......

public class notifyHelper  {
public void sendNotification(Activity caller, Class<?> activityToLaunch, String title, String msg, int numberOfEvents, boolean flashLed, boolean vibrate, int ID) {
    NotificationManager notifier = (NotificationManager) caller.getSystemService(Context.NOTIFICATION_SERVICE);

    // Create this outside the button so we can increment the number drawn over the notification icon.
    // This indicates the number of alerts for this event.
    long whenTo = System.currentTimeMillis() + (1000 * 60 * 15);
    final Notification notify = new Notification(R.drawable.icon, "", whenTo);

    notify.icon = R.drawable.icon;
    notify.tickerText = "TV Spored ++";
    notify.when = whenTo;
    notify.number = numberOfEvents;
    notify.flags |= Notification.FLAG_AUTO_CANCEL;

    if (flashLed) {
    // add lights
        notify.flags |= Notification.FLAG_SHOW_LIGHTS;
        notify.ledARGB = Color.CYAN;
        notify.ledOnMS = 500;
        notify.ledOffMS = 500;
        notify.defaults |= Notification.DEFAULT_SOUND;
    }

    if (vibrate) {

        notify.vibrate = new long[] {100, 200, 200, 200, 200, 200, 1000, 200, 200, 200, 1000, 200};
    }

    Intent toLaunch = new Intent(caller, activityToLaunch);
    PendingIntent intentBack = PendingIntent.getActivity(caller, 0, toLaunch, 0);

    notify.setLatestEventInfo(caller, title, msg, intentBack);
    notifier.notify(ID, notify);
}

public static void clear(Activity caller) {
    NotificationManager notifier = (NotificationManager) caller.getSystemService(Context.NOTIFICATION_SERVICE);
    notifier.cancelAll();
}
}

无论我做什么(看看什么时候)，这个通知总是在调用时显示...我如何设置通知时间？

感谢您的回答!

是什么让您认为有一种方法可以创建非即时通知？

来自 http://developer.android.com/reference/android/app/Notification.html你可以看到一些重要的事情。首先，您正在使用的构造函数已被弃用——您应该考虑使用 http://developer.android.com/reference/android/app/Notification.Builder.html反而。但更重要的是，第三个参数不是“何时显示通知”，而是在通知本身的时间字段中显示的时间。想象一下……调用你的电话，不要接听(为了引起未接来电通知)。然后拉下通知抽屉，注意右下角显示的时间。
