Question

我正在开发音乐应用程序，因此我需要在通知栏上显示通知。为此，我正在使用自定义通知。以下是Android Oreo通知的代码

String NOTIFICATION_CHANNEL_ID = "001";
        RemoteViews notificationLayout = new RemoteViews(getPackageName(), R.layout.mynotification);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "My Notifications", NotificationManager.IMPORTANCE_LOW);
            notificationChannel.setDescription("Channel description");

            NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
            notificationManager.createNotificationChannel(notificationChannel);

            NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(MainActivity.this, NOTIFICATION_CHANNEL_ID);
            notificationBuilder.setSmallIcon(R.drawable.exo_edit_mode_logo)
                    .setCustomContentView(notificationLayout)
                    .setAutoCancel(true)
                    .setPriority(Notification.PRIORITY_DEFAULT);

            NotificationManagerCompat com = NotificationManagerCompat.from(this);
            com.notify(001, notificationBuilder.build());

        }

此代码工作正常，但是从通知栏滑动通知时，它将被删除。但是我的要求不是在滑动通知时删除。我尝试使用 setAutoCancel（true）和 setAutoCancel（false）。但是不起作用，它将被删除。那么如何在此处粘贴通知。

请指导我该怎么做。

预先感谢

Answer 1

您必须添加此setOngoing(true)

尝试：

Notification.Builder builder = new Notification.Builder(this, CHANNEL_ID)
                .setContentTitle(getString(R.string.app_name))
                .setContentText("Text")
                .setSmallIcon(R.mipmap.ic_launcher)
                .setAutoCancel(false)
                .setOngoing(true);

Notification notification = builder.build();

使用setOngoing(true)实现这一目标
