Retrofit
➢ Model (POJO)
➢ Interface Service
➢ Adapter / Call
➢ Converter such as GSON
Retrofit
public class Question { private String question; private String url;
public String getQuestion() { return question;}
public String getUrl() { return url;}}
Retrofit (Model POJO)
public interface RetrofitRequestService {
@GET("/questions")
Call<List<Question>> ques();
}
Retrofit (Service Interface)
Retrofit mRestAdapter = new Retrofit
.Builder()
.baseUrl("http://private-9adb36-crashback.apiary-mock.com/")
.addConverterFactory(GsonConverterFactory.create())
.build();
service = mRestAdapter.create(RetrofitRequestService.class);
Retrofit (Adapter / Call)
Call<List<Question>> call = service.ques();
//call on another thread not in main threadcall.enqueue(new Callback<List<Question>>() { @Override public void onResponse(Call<List<Question>> call, Response<List<Question>> response) { System.out.println("Question = " + response.body().get(0).getQuestion()); System.out.println("url = " + response.body().get(0).getUrl()); }
@Override public void onFailure(Call<List<Question>> call, Throwable t) { }});
