Sample code:

xml:

<my-object>
    <message>hello world</message>
    <count>10</count>
</my-object>

import org.simpleframework.xml.Default;
import org.simpleframework.xml.DefaultType;
import org.simpleframework.xml.Element;

@Default(value = DefaultType.FIELD)
final class MyObject {
  @Element private String message;
  @Element private int count;

  public MyObject() {}

  public MyObject(String message, int count) {
    this.message = message;
    this.count = count;
  }

  public void setMessage(String message) {
    this.message = message;
  }

  public String getMessage() {
    return message;
  }

  public void setCount(int count) {
    this.count = count;
  }

  public int getCount() {
    return count;
  }
}

    Format format = new Format(0, null, new HyphenStyle(), Verbosity.HIGH);
    Persister persister = new Persister(format);
    Retrofit retrofit =
        new Retrofit.Builder()
            .baseUrl(server.url("/"))
            .addConverterFactory(SimpleXmlConverterFactory.create(persister))
            .build();
    service = retrofit.create(Service.class);

  interface Service {
    @GET("/")
    Call<MyObject> get();

    @POST("/")
    Call<MyObject> post(@Body MyObject impl);

    @GET("/")
    Call<String> wrongClass();
  }
