Answer 1

Créez d'abord l'interface comme celui-ci ....

public interface GitHubService { 
     @GET("v0/topstories.json") 
     Call<List<Long>> listRepos(); 
    } 

et utiliser dans votre activité comme ça .....

 Retrofit retrofit = new Retrofit.Builder() 
       .baseUrl("https://hacker-news.firebaseio.com/").addConverterFactory(GsonConverterFactory.create()) 
       .build(); 

     GitHubService api = retrofit.create(GitHubService.class); 

     api.listRepos().enqueue(new Callback<List<Long>>() { 
      @Override 
      public void onResponse(Call<List<Long>> call, Response<List<Long>> response) { 
       if (response.isSuccessful()) { 

        // do operations here 
        String number = ""; 
        for (int i = 0; i < response.body().size(); i++) 
         number += response.body().get(i) + ", "; 

        ((TextView) findViewById(R.id.number)).setText(number); 
       } else 
        Toast.makeText(MainActivity.this, response.errorBody().toString(), Toast.LENGTH_LONG).show(); 
      } 

      @Override 
      public void onFailure(Call<List<Long>> call, Throwable t) { 
      Toast.makeText(MainActivity.this, t.getMessage().toString(), Toast.LENGTH_LONG).show(); 
      } 
     }); 

et utiliser cette depandencies dans votre gradle ...

> compile 'com.squareup.retrofit2:retrofit:2.3.0' 
>  compile 'com.squareup.retrofit2:converter-gson:2.+' 

Answer 2

POJO signifie Plain Old Java Objects, si vous obtenez un tableau entier comme réponse, analyser pour dans l'interface de mise à niveau,

quelque chose comme ceci:

@GET(... you url) 
Call<List<Integer>>getHackerNews() 

Attendez-vous à un tableau ou une liste d'entiers.
