推荐答案

一旦你扫描并找到一个 BluetoothDevice 调用方法 BluetoothDevice.getBluetoothClass().这将返回一个 BluetoothClass 对象，文档 声明如下:

Once you scan and find a BluetoothDevice call the method BluetoothDevice.getBluetoothClass(). This will return a BluetoothClass object and the documentation states the following:

代表一个蓝牙类，描述一般特性和设备的能力.例如，一个蓝牙类将指定一般设备类型，例如电话、计算机或耳机，以及它是否能够提供诸如音频或电话.

Represents a Bluetooth class, which describes general characteristics and capabilities of a device. For example, a Bluetooth class will specify the general device type such as a phone, a computer, or headset, and whether it's capable of services such as audio or telephony.

因此，在您允许用户选择要连接的设备或过滤显示的 BluetoothDevice 列表之前，请尝试查看 BluetoothClass 是否具有正确的设备类型.

So before you allow the user to select the device to connect to, or to filter the list of BluetoothDevices shown, try seeing if the BluetoothClass has the correct device type.

BluetoothClass bluetoothClass = bluetoothDevice.getBluetoothClass();
if(bluetoothClass.getDeviceClass() == BluetoothClass.Device.AUDIO_VIDEO_HEADPHONES) {
    // allow user to select this device. I'm not sure exactly which type
    // headphones will be but this is a good guess. You can connect to
    // your Bluetooth headset to find out for sure.
}

可以在此处找到不同的设备类常量，以防您想区分进一步按设备类别.
