Android / Java - Gson model object without making container object to unwrap root element

README.md

The following pattern helps to avoid making a PersonWrapper class that just has one property of Person the_person.

Use by calling

Person person = Person.fromJson(responseFromNetworkCall);

Example json you would be unwrapping seen in person.json.

Person.java

public class Person {

    public static class Container {
        public Person the_person;
    }

    public static Person fromJson(String json) {
        Gson gson = new Gson();
        Person.Container container = gson.fromJson(json, Person.Container.class);
        return container.the_person;
    }

    @SerializedName("id") public Integer id;
    @SerializedName("first_name") public String firstName;
    @SerializedName("middle_name") public String middleName;
    @SerializedName("last_name") public String lastName;

}

person.json

{
  "the_person": {
    "id": 123,
    "first_name": "robert",
    "middle_name": "adam",
    "last_name": "johns"
  }
}
