问是否可以仅显示配对的、打开的和范围内的蓝牙设备的活动列表，而不是显示所有以前配对的设备？

EN

BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(BluetoothDevice.ACTION_FOUND);
registerReceiver(receiver, intentFilter);
bluetoothAdapter.startDiscovery();

...
private ArrayList<BluetoothDevice> devices = new ArrayList<>();
private final BroadcastReceiver receiver = new BroadcastReceiver(){
    public void onReceive(Context context, Intent intent){
        String action = intent.getAction();
        if(action.equals(BluetoothAdapter.ACTION_FOUND)){
            BluetoothDevice bluetoothDevice = (BluetoothDevice) intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
            devices.add(bluetoothDevice);
        }
    }
};
