I am trying to make my list view popular with a json, it check the information of another json and return me a link in which I will use to fill photos but everything goes right with you setar link in a class but when it comes time to receive it always get null
GET.class <- class where I get the 1st json for popular
class GET extends AsyncTask<String,String,String> {
Activity activity;
String nome;
String nome2;
String idpaciente;
String idmedico;
ListView lv;
public GET(Activity activity, ListView lv, String nome) {
this.activity = activity;
this.lv = lv;
this.nome = nome;
}

urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.connect();
InputStream in = new BufferedInputStream(urlConnection.getInputStream());
reader = new BufferedReader(new InputStreamReader(in));
String line = "";
StringBuffer buffer = new StringBuffer();
while ((line = reader.readLine()) != null) {
buffer.append(line);

resposta = buffer.toString();

guardaFoto.class <- class where I store and pick up the links
public class guardaFoto {
String foto;
public void setPicture(String foto) {
this.foto = foto;
}
public String getPicture() { return foto; }
}
Using breakpoints I can see that the guardaFoto.class received the link but when trying to receive always returns null
The part of
whilewhich arrow the link onsetPictute()it will buy the id and will always be a link that I will receive so it would not be the case to use a list.– Matheus Rohwedder
However I would have to receive this link by
getPicture()and everything is being done on onCreate because they are images of users who would stand next to their medical appointments– Matheus Rohwedder
Well, you have two solutions, by a Reader and inform when you pick up a new one (or arrange your onPostExecute), or else Voce passes the Imageview to your Task and already arrow the image after downloading that is easier.
