You can always <code>cancel()</code> the <code>Notification</code> from whatever is being invoked by the action (e.g., in <code>onCreate()</code> of the activity tied to the <code>PendingIntent</code> you supply to <code>addAction()</code>).

When you called notify on the notification manager you gave it an id - that is the unique id you can use to access it later (this is from the notification manager:

<pre><code>notify(int id, Notification notification)
</code></pre>

To cancel, you would call:

<pre><code>cancel(int id)
</code></pre>

with the same id. So, basically, you need to keep track of the id or possibly put the id into a Bundle you add to the Intent inside the PendingIntent?

I found that when you use the action buttons in expanded notifications, you have to write extra code and you are more constrained.

You have to manually cancel your notification when the user clicks an action button. The notification is only cancelled automatically for the default action. 

Also if you start a broadcast receiver from the button, the notification drawer doesn't close. 

I ended up creating a new NotificationActivity to address these issues. This intermediary activity without any UI cancels the notification and then starts the activity I really wanted to start from the notification. 

I've posted sample code in a related post <a href="https://stackoverflow.com/questions/18261969/clicking-android-notification-actions-does-not-close-notification-drawer/21783203">Clicking Android Notification Actions does not close Notification drawer</a>.

blocks|key|285679|text|在我看来，使用BroadcastReceiver是一种更简洁的取消通知的方式：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|285680|在AndroidManifest.xml中：|285681|<receiver+

In my opinion using a <code>BroadcastReceiver</code> is a cleaner way to cancel a Notification:

In AndroidManifest.xml:

<pre><code>&lt;receiver 
 android:name=.NotificationCancelReceiver" &gt;
 &lt;intent-filter android:priority="999" &gt;
 &lt;action android:name="com.example.cancel" /&gt;
 &lt;/intent-filter&gt;
&lt;/receiver&gt;
</code></pre>

In java File:

<pre><code>Intent cancel = new Intent("com.example.cancel");
PendingIntent cancelP = PendingIntent.getBroadcast(context, 0, cancel, PendingIntent.FLAG_CANCEL_CURRENT);

NotificationCompat.Action actions[] = new NotificationCompat.Action[1];
</code></pre>

NotificationCancelReceiver

<pre><code>public class NotificationCancelReceiver extends BroadcastReceiver {
 @Override
 public void onReceive(Context context, Intent intent) {
 //Cancel your ongoing Notification
 };
}
</code></pre>

blocks|key|502467|text|只需放入这一行：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|502468|+builder.setAutoCancel(true);|code-block|syntax|javascript|502469|完整的代码是：|502470|NotificationCompat.Builder+builder+=+new+NotificationCompat.Builder(this);

Just put this line : 

<pre><code> builder.setAutoCancel(true);
</code></pre>

And the full code is :

<pre><code>NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
 builder.setSmallIcon(android.R.drawable.ic_dialog_alert);
 Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.google.co.in/"));
 PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
 builder.setContentIntent(pendingIntent);
 builder.setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.misti_ic));
 builder.setContentTitle("Notifications Title");
 builder.setContentText("Your notification content here.");
 builder.setSubText("Tap to view the website.");
 Toast.makeText(getApplicationContext(), "The notification has been created!!", Toast.LENGTH_LONG).show();

 NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
 builder.setAutoCancel(true);
 // Will display the notification in the notification bar
 notificationManager.notify(1, builder.build());
</code></pre>

You will need to run the following code after your intent is fired to remove the notification.

<pre><code>NotificationManagerCompat.from(this).cancel(null, notificationId);
</code></pre>

NB: notificationId is the same id passed to run your notification

Since API level 16 (Jelly Bean), there is the possibility to add actions to a notification with

<pre><code>builder.addAction(iconId, title, intent);
</code></pre>

But when I add an action to a notification and the action is pressed, the notification is not going to be dismissed.
When the notification itself is being clicked, it can be dismissed with

<pre><code>notification.flags = Notification.FLAG_AUTO_CANCEL;
</code></pre>

or

<pre><code>builder.setAutoCancel(true);
</code></pre>

But obviously, this has nothing to with the actions associated to the notification.

Any hints? Or is this not part of the API yet? I did not find anything.

How to dismiss notification after action has been clicked

Android

从API级别16 (Jelly Bean)开始，可以使用以下命令向通知添加操作builder.addAction(iconId, title, intent);但是，当我向通知中添加一个操作并按下该操作时，该通知不会被驳回。单击通知本身时，可以使用以下命令解除通知notification.flags = Notific...
