blocks|key|1156838|text|这很简单。你必须在你的NotificationManager上调用cancel或cancelAll。cancel方法的参数是需要取消的通知的ID。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1156839|查看接口：http://developer.android.com/reference/android/app/NotificationManager.html#cancel(int)|1156840|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.android.com/reference/android/app/NotificationManager.html#cancel(int)^0|X|6|14|9|0|5|2F|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]|$9|S|A|T|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|U|8|@]|D|@$9|V|A|W|1|X]]|E|$]]|$1|H|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|I|$J|$5|K|L|M|E|$N|O]]]]

This is quite simple. You have to call <code>cancel</code> or <code>cancelAll</code> on your NotificationManager. The parameter of the cancel method is the ID of the notification that should be canceled.

See the API: <a href="http://developer.android.com/reference/android/app/NotificationManager.html#cancel(int)" rel="noreferrer">http://developer.android.com/reference/android/app/NotificationManager.html#cancel(int)</a>

blocks|key|942738|text|你可以试试这个快速代码|type|unstyled|depth|inlineStyleRanges|entityRanges|data|942739|public+static+void+cancelNotification(Context+ctx,+int+notifyId)+{
++++String+ns+=+Context.NOTIFICATION_SERVICE;
++++NotificationManager+nMgr+=+(NotificationManager)+ctx.getSystemService(ns);

}|code-block|syntax|javascript|942740|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

You can try this quick code

<pre><code>public static void cancelNotification(Context ctx, int notifyId) {
 String ns = Context.NOTIFICATION_SERVICE;
 NotificationManager nMgr = (NotificationManager) ctx.getSystemService(ns);
 nMgr.cancel(notifyId);
}
</code></pre>

blocks|key|1156997|text|您还可以在通知管理器上调用cancelAll，因此您甚至不必担心通知ids。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1156998|NotificationManager+notifManager=+(NotificationManager)+context.getSystemService(Context.NOTIFICATION_SERVICE);
notifManager.cancelAll();|code-block|syntax|javascript|1156999|编辑:我被否决了，所以也许我应该指定这只会从你的应用程序中删除通知。|1157000|entityMap^0|D|9|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|S|8|@]|D|@]|E|$]]|$1|M|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|N|$]]

You can also call <code>cancelAll</code> on the notification manager, so you don't even have to worry about the notification ids.

<pre><code>NotificationManager notifManager= (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
notifManager.cancelAll();
</code></pre>

EDIT : I was downvoted so maybe I should specify that this will only remove the notification from your application.

blocks|key|1157020|text|只需设置setAutoCancel(True)，如以下代码所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1157021|Intent+resultIntent+=+new+Intent(GameLevelsActivity.this,+NotificationReceiverActivityAdv.class);

simply set setAutoCancel(True) like the following code:

<pre><code>Intent resultIntent = new Intent(GameLevelsActivity.this, NotificationReceiverActivityAdv.class);

PendingIntent resultPendingIntent =
 PendingIntent.getActivity(
 GameLevelsActivity.this,
 0,

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
 getApplicationContext()).setSmallIcon(R.drawable.icon)
 .setContentTitle(adv_title)
 .setContentText(adv_desc)
 .setContentIntent(resultPendingIntent)
 //HERE IS WHAT YOY NEED:
 .setAutoCancel(true);

NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(547, mBuilder.build());`
</code></pre>

A short one Liner of this is:

Or to cancel all notifications is:

Use the NotificationManager to cancel your notification. You only need to provide your notification id

mNotificationManager.cancel(YOUR_NOTIFICATION_ID);

On Android API >=23 you can do somehting like this to remove a group of notifications.

<pre><code> for (StatusBarNotification statusBarNotification : mNotificationManager.getActiveNotifications()) {
 if (KEY_MESSAGE_GROUP.equals(statusBarNotification.getGroupKey())) {
 mNotificationManager.cancel(statusBarNotification.getId());
 }
