推荐答案

您应该创建一个包含要传递的数据的类，并从Serializable或Parcelable扩展该数据，然后可以将该类的对象放入Extra到Intent并在Service

you should create a class containing your data to be passed and extend that from Serializable or Parcelable and then you can put an object of that class as an Extra to your Intent and use it in your Service

正如rom4ek所提到的，BluetoothDevice已经实现了Parcelable，您要做的就是:

EDIT : as rom4ek mentioned, BluetoothDevice is already implements Parcelable and all you have to do is :

Bundle b = new Bundle();
b.putParcelable("data", yourBluetoothDeviceObject);
yourIntent.putExtra(b);

以及用于检索数据:

Bundle b = yourIntent.getExtra();
BluetoothDevice device = (BluetoothDevice) b.getParcelable("data");
