是的，你可以过滤掉它。

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
  public void onReceive(Context context, Intent intent) {
    String action = intent.getAction();
    if (BluetoothDevice.ACTION_FOUND.equals(action)) {
      // Discovery has found a device. Get the BluetoothDevice
      // object and its info from the Intent.
      BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
      String deviceName = device.getName();
      // 
      // use try-catch to keep tying on the logic -- John Melody added
      try {
        if (deviceName.contains("somethingsomething")) {
          System.out.println(String.format("Ok %s", deviceName));
        }
      } catch(Exception e) {
        e.printStackTrace();
      }
    //
    }
  }
};
