安卓：在使用时通知您的应用程序在后台运行AUTO-取消 [英] Android: Using AUTO-CANCEL on a notification when your app is running in the background

问题描述

我已经看过了所有其他的AUTO-取消 - 不工作的问题在这里，他们似乎都涉及到，我不犯错误。我曾经尝试都

I have looked at all the other AUTO-CANCEL-not-working questions here, and they all seem to involve mistakes that I am not making. I have tried both

builder.setAutoCancel(true);

和

Notification notif = builder.build();
notif.flags |= Notification.FLAG_AUTO_CANCEL;

无论是作品。

Neither works.

我使用NotificationCompat因为我最小的API为8。这里是我的全部code。在这个特殊的通知，我不打电话的意图，因为我不需要用户做任何事。

I am using NotificationCompat since my minimum API is 8. Here is my full code. In this particular notification, I am not calling an intent, since I don't need the user to do anything.

NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
builder.setContentTitle(getString(R.string.app_name) + ": my title");
builder.setContentText(message);
builder.setSmallIcon(R.drawable.notification_icon);

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.prog_icon);
builder.setLargeIcon(bitmap);

builder.setAutoCancel(true); // dismiss notification on user click

NotificationManager notiManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
notiManager.notify(MY_NOTI_MANAGER_ID, builder.build());

的通知只显示完美。你可以刷卡将其清除。但是，简单地点击它并没有解雇通知。它刚好亮起，呆在那里。

The notification displays just perfectly. You can swipe to clear it. But simply tapping it does not dismiss the notification. It just lights up and stay there.

之间我的code和他人张贴在这里的一些可能的不同： 1）我使用NotificationCompat（这不应该有所作为，但是我们以前听说过这一点）。 2）由于我的通知很简单，我不重视的意图。

Some possible differences between my code and others' posted here: 1) I am using NotificationCompat (which should not make a difference, but we've heard that before). 2) Since my notification is simple, I do not attach an intent.

请让我知道如果您有任何见解。

Please let me know if you have any insights.

编辑：我的目的是驳回通知没有前景化我的后台程序。

My purpose is to dismiss a notification without foregrounding my background app.

推荐答案

那么显然你的执行的需要挂起的意图。

So apparently you do need a pending intent.

在<一个href="http://stackoverflow.com/questions/7040742/android-notification-manager-having-a-notification-without-an-intent">Android - 通知经理，有一个通知，没有意图，我发现了一个解决方案，抓住当前活动的应用程序作为待处理的意图（这样你就不必开始自己的活动，以驳回通知）。

At Android - notification manager, having a notification without an intent, I found a solution that grabs the current active application as your pending intent (so that you don't have to start your own activity in order to dismiss the notification).

我刚刚添加了下面两行code（设置自动取消后右）：

I just added the following two lines of code (right after setting the auto-cancel):

PendingIntent notifyPIntent = 
    PendingIntent.getActivity(getApplicationContext(), 0, new Intent(), 0);     
builder.setContentIntent(notifyPIntent);

这真是棒极了。我要说的是，如果你不想让你的活动一下您的通知重新启动作为用户的结果，那么这就是你最好的选择。

It worked great. I would say that if you don't want your activity to restart as a result of the user clicking your notification, then this is your best option.
