我从来没有试过有一个服务中的一个关键监听器，但谷歌从一点点帮助，我发现这一点：的体积变化监听器？

I have never tried to have a key listener inside a service, but with a little help from Google I found this: Volume change listener?

看来，正常的关键事件只能从活动进行处理。我没有时间去尝试了这一点我自己，但捕捉长期的点击有可能的答案从链接和卢克斯的回答结合起来。 据我了解有关BroadcastReceivers，你想创建一个接收器，该通知服务每当有人点击音量按钮。

It seems that normal key events can only be handled from Activities. I do not have time to try this out myself, but for capturing long clicks it might be possible to combine the answer from the link and Lukes answer. From what I understand about BroadcastReceivers, you would want to create a receiver, that notify the Service whenever someone click the volume buttons.
