Android检查是否允许声音通知设置已启用或以编程方式禁用
因此，我已经关注此链接我的问题。但是我认为答案已经过时了。代码不起作用。
int importance = manager.getImportance();
boolean soundAllowed = importance < 0 || importance >= NotificationManager.IMPORTANCE_DEFAULT;
因此，这是我目前用来检测通知声的条件是打开还是关闭（管理器是通知manager类的对象）。但这不起作用。
我想检查通知的声音是打开还是关闭。如果关闭，请通知用户将其打开。
谢谢你的阅读
So I have followed this link to solve my problem. but i think the answer is out dated. the code is not working.
int importance = manager.getImportance();
boolean soundAllowed = importance < 0 || importance >= NotificationManager.IMPORTANCE_DEFAULT;
so this is condition i'm currently using to detect if sound of notification is on or off (where manager is object of NotificationManager class). but it's not working.
i want to check if sound of notification is on or off. if it is off then notify user to turn it on.
thank you for reading

在您的下面代码中，如果用户尚未指定任何通知或更高的通知重要性：在各处显示，发出噪音和窥视。然后，您的声音是真的。
我认为您应该删除重要性＆lt; 0因此，您只有用户才能获得此声音变量，这对通知声音具有更高的重视，
请在此处检查值，以更加清晰。

In your below code if user has not specified anything for notification or if he has Higher notification importance: shows everywhere, makes noise and peeks. Then your soundAllowed is true.
I think you should remove importance < 0 so you will get this soundAllowed variable only true with user has gave higher importance to notification sounds
Please check the values here for more clarity.
