android - 我如何以编程方式知道 Android O 上是否启用了通知 channel ？

Question

查看文档我可以看到检查通知 channel 所有属性的方法，但我找不到检查 channel 本身是启用还是禁用的方法。

我错过了什么吗？

Official Documentation有你的答案:

You can call the following two methods to discover the settings a user has applied to a notification channel:

• o retrieve a single notification channel, you can call getNotificationChannel().
• To retrieve all notification channels belonging to your app, you can call getNotificationChannels().

After you have the NotificationChannel, you can use methods such as getVibrationPattern() and getSound() to find out what settings the user currently has. To find out if a user blocked a notification channel, you can call getImportance(). If the notification channel is blocked, getImportance() returns IMPORTANCE_NONE.

因此 getImportance() 会告诉您通知 channel 是否被阻止。
