I'd like to know how to create a notification that doesn't show the icon in the statusbar.

There is a way to hide it?

推荐答案

从Android 4.1（API级别16）开始，可以指定通知的 priority 。如果您将该标记设置为 PRIORITY_MIN 通知图标不会显示在状态栏上。

Since Android 4.1 (API level 16) it's possible to specify a notification's priority. If you set that flag to PRIORITY_MIN the notification icon won't show up on the statusbar.

notification.priority = Notification.PRIORITY_MIN;

或者如果您使用 Notification.Builder ：

builder.setPriority(Notification.PRIORITY_MIN);

从Android 8.0 Oreo开始（API级别26）您必须将通知的 NotificationChannel 的重要性设置为 IMPORTANCE_MIN ：

As of Android 8.0 Oreo (API level 26) you have to set the importance of the notification's NotificationChannel to IMPORTANCE_MIN:

NotificationChannel channel = 
      new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_MIN);
notificationManager.createNotificationChannel(channel);
...
builder.setChannelId(channel.getId())
