How set the first element in a spinner?

Question

in my app Android I have a set of data I want to bind to a spinner.
But of these I would like a particular value to be seen as the first in the spinner list.

public String [] getDescriptionCategories () {
     Set <String> categories = products.keySet ();
     String [] result = new String [categorie.size ()];
     int i = 0;
     for (String cat: categories) {
         result [i ++] = cat;
     }

     return result;
 }

The result is ["Altro","Prodotti","Utenti"], but I wish it was ["Utenti", "Prodotti", "Altro"]

How do I set it up?

You should use return Collections.reverse(result);. It will reverse your list. If you want to sort the list by alphabetical order, see this answer. Hope it helps :)
