I have a listView that returns two strings to one each row. The code and the name of a country, I would not like to present the code but I need it for when the user clicks on the line to get the code and search the bank. My line is like "345 Brazil", because I need the code I needed to get only it with adapter.getItem(position) . Is there any way to do this? Thank you in advance!
How to make the "adapter.getItemPosition" get only part of the String and hide the other party at the time of displaying the ListView?

I suppose your adapter is of type ArrayAdapter<String> and hence its difficulty.
My suggestion is to declare a class named Country and declare the Adapter as ArrayList<Pais> .
Begin by declaring the Parent class:
public class Pais{
String nome;
String codigo;
public Pais(String nome, String codigo){
this.nome = nome;
this.codigo = codigo;
}
public String getNome(){
return nome;
}
public String getCodigo(){
return codigo;
}
}
Declare the array , which is used by the Adapter as ArrayList<Pais> and pass it to ArrayAdapter<Pais> .
When you need the name of the country do: getItem(position).getNome();
When you need the country code do: getItem(position).getCodigo();

You can save the whole object to your Adapter , in your object you implement toString which is the method that Adapter will use to show in ListView , and when you need to get the code for example you have the object saved with all its attributes.

I solved the problem guys, it was my gambiarra but it worked, now I only get the number of the string adapter.getItem(position).replaceAll("[^0-9]*", "");
But how could I hide this number? Display only the name of the country?
