英文:
Gson doesn't serialyse mac adresses
问题
我想保存蓝牙设备的Mac地址，所以我使用Gson进行序列化，将其转换为String类型，但没有任何返回。
Gson gson = new Gson();
Log.d("my device", String.valueOf(myBluetoothDevice)); //93:39:1B:04:00:71
String dev = gson.toJson(myBluetoothDevice, BluetoothDevice.class);
Log.d("my device after", dev); //{}
谢谢帮助

Log.d("my device", String.valueOf(myBluetoothDevice)); //93:39:1B:04:00:71
String dev = gson.toJson(myBluetoothDevice, BluetoothDevice.class);

获取BluetoothDevice的地址，请调用getAddress方法：
String address = myBluetoothDevice.getAddress();
// address = 00:11:22:AA:BB:CC
如果您想将字符串转换为JSON表示形式的字符串，基本上只需添加引号，那么您可以使用gson.toJson()：
String addressInJson = gson.toJson(myBluetoothDevice.getAddress());
// addressInJson = "00:11:22:AA:BB:CC"
英文:
To get the address of a BluetoothDevice, call the getAddress method:
String address = myBluetoothDevice.getAddress();
// address = 00:11:22:AA:BB:CC
If you want to convert the String into a JSON representation of the string, which basically just adds quotes, then you can use gson.toJson():
String addressInJson = gson.toJson(myBluetoothDevice.getAddress());
// addressInJson = "00:11:22:AA:BB:CC"
