    推荐答案

    扫描并找到BluetoothDevice后,调用方法BluetoothDevice.getBluetoothClass().这将返回一个BluetoothClass对象,并且文档指出以下内容:

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

    因此,在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.进一步根据设备类别.
