最近有个需求是蓝牙界面只显示耳机，不显示其他设备，所以看了一下蓝牙相关代码。

在BluetoothClass中定义了蓝牙设备的类型
frameworks/base/core/java/android/bluetooth/BluetoothClass.java

    public static class Device {
   
   
        private static final int BITMASK = 0x1FFC;

        /**
         * Defines all major device class constants.
         * <p>See {@link BluetoothClass.Device} for minor classes.
         */
        public static class Major {
   
   
            private static final int BITMASK = 0x1F00;

            public static final int MISC = 0x0000;
            public static final int COMPUTER = 0x0100;
            public static final int PHONE = 0x0200;
            public static final int NETWORKING = 0x0300;
            public static final int AUDIO_VIDEO = 0x0400;
            public static final int PERIPHERAL = 0x0500;
            public static final int IMAGING = 0x0600;
            public static final int WEARABLE = 0x0700;
            public static final int TOY = 0x0800;
            public static final int HEALTH = 0x0900;
            public static final int UNCATEGORIZED = 0x1F00;
        }

        // Devices in the COMPUTER major class
        public static
