My question is how to take the request JSON and put it in an Arraylist so I can inflate the Recyclerview. Thanks in advance.

Adds a CoverterFactory the instantiation of Retrofit, through the addConverterFactory, and in case JSON returns an Array, you can easily map it to an Arraylist.

You can convert your JSON into a Jsonobject and go capturing its attributes.

JSON

    {
     "nome": "José da Silva"
     "idade" : 30
     }

JAVA

JSONObject jsonObj= new JSONObject("seu json aqui");
String nome = jsonObj.getString("nome");
int idade = jsonObj.getInt("idade");

Exit

Log.d("App", "Nome: " + nome);//José da Silva
Log.d("App", "Idade: " + idade);//30

Another alternative would be the GSON library, in which you directly convert an Object to Json and a Json to Object. Link: http://www.vogella.com/tutorials/JavaLibrary-Gson/article.html

  • I managed to fix it. Thanks for the help!
