In my case I needed to serialize and deserialize only one class to XML. For everything else I needed Json. So I registered my adapters like this:

retrofit = new Retrofit.Builder()
                .baseUrl(BuildConfig.BASE_URL)
                .addConverterFactory(EditUserXmlConverterFactory.create())
                .addConverterFactory(GsonConverterFactory.create(createGson()))
                .client(httpClient.build())
                .build();

since I could not extend SimpleXmlConverterFactory (unfortunately) I had to use my own class and change the following line:

if (!(type instanceof Class)) return null;

to

if (type != NeedToBeXML.class) return null;

This way only responses and requests of type NeedToBeXML are converted to XML - and everything else JSON.
