Question

所以我创建了一个应用程序，用户可以在其中创建通知作为提醒。该通知会弹出并运行，但我想在用户单击某个操作时删除该通知。这是我的代码：

            Intent intent =  new Intent();
            PendingIntent pIntent = PendingIntent.getActivity(MainActivity.this,0,intent,0);

            Notification notif = new Notification.Builder(MainActivity.this)
                    .setSmallIcon(R.drawable.notification)
                    .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.notification))
                    .setOngoing(switchState)
                    .setContentTitle("Noteify")
                    .setContentText(notifEditText.getText().toString())
                    .setPriority(Notification.PRIORITY_MAX)
                    .addAction(R.drawable.delete,"Delete",pIntent)
                    .setContentIntent(pIntent).getNotification();


            NotificationManager nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
            nm.notify(0,notif);

我添加了操作，但我不知道如何删除通知。

Answer 1

简单，只需称呼：

mBuilder.setAutoCancel(true);

在此

下面

NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(context)
    .setContentTitle("MyApp")
    .setContentText(message)
    .setDefaults(Notification.DEFAULT_ALL)
    .setAutoCancel(true)
    .setContentIntent(contentIntent)
    .setSmallIcon(icon);

Answer 2

Gowthaman M说的是正确的，将setAutoCancel(true);添加到Notification对象。

只需编辑您的代码，如下所示

        Intent intent =  new Intent();
        PendingIntent pIntent = PendingIntent.getActivity(MainActivity.this,0,intent,0);

        Notification notif = new Notification.Builder(MainActivity.this)
            .setSmallIcon(R.drawable.notification)
            .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.notification))
            .setOngoing(switchState)
            .setContentTitle("Noteify")
            .setAutoCancel(true)
            .setContentText(notifEditText.getText().toString())
            .setPriority(Notification.PRIORITY_MAX)
            .addAction(R.drawable.delete, "Delete", pIntent)
            .setContentIntent(pIntent).getNotification();


        NotificationManager nm = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
        nm.notify(0,notif);

如何设置通知的操作？
