推荐答案

我不确定是否有标准化的方法或是否可能.您有谷歌搜索了吗?如果找到了，您找到了什么?我会自己提供一些链接，因为它们可能会导致某些问题:

I'm not sure if there's a standardized way of doing this or if it's possible at all. Have you Googled a bit and if so what did you find? I'm gonna offer a few links myself as they might lead to something:

• 首先，我要研究 android.bluetooth. BluetoothHeadset 类.它将已连接的耳机列为通用 BluetoothDevice .从那里看来，您可以发出特定于供应商的命令来获取不同种类的传感器信息(例如电池电量).

• First of all I'd look into the android.bluetooth.BluetoothHeadset class. It will list connected headsets as generic BluetoothDevices. From there it seems like you can issue vendor specific commands to get different kinds of sensor information (like battery level).

检查此博客帖子，内容涉及从Android访问Plantronics耳机传感器.甚至还有一个带有源代码的示例应用程序.

Check this blog post from a Plantronics employee regarding Plantronics headset sensor access from Android. There's even an example app with source code.

检查 Sony附加SDK 用于使用其SmartApp系统与某些类型的耳机接口
