Changing a listview in onItemClickListener

Hello!

I'm starting to develop to android, and I have a big doubt. I know how to work around this problem but I don't like the way I found to do it.
So I have a listview perfectly populated, and have a onItemClickListener:

public void onItemClick(AdapterView<?> adapter, View view, int pos, long id) {
 
                                Player player = _game.getPlayer();
 
                                ListView lstview = (ListView) findViewById(R.id.list);
 
                                if(!player.hasPlayed(pos) || !player.hasPlayed() || !_game.hasGameEnded()) {
 
                                        LinearLayout layout = (LinearLayout) view;
 
                                        layout = (LinearLayout) layout.getChildAt(0);
 
                                        TextView txt1 = (TextView) layout.getChildAt(0);
 
                                        layout = (LinearLayout) lstview.getChildAt(pos);
 
                                        layout = (LinearLayout) layout.getChildAt(0);
 
                                        TextView txt2 = (TextView) layout.getChildAt(0);
 
                                        System.out.println(txt1.getText());
 
                                        System.out.println(txt2.getText());
 
                                        txt2.setText("TRETA");
 
                                        System.out.println(txt1.getText());
 
                                        System.out.println(txt2.getText());
 
                                        player.checkPlay(pos);
 
                                        player.checkPlay(Player.BONUS);
 
                                        _game.changeTab(0);
 
                                }
 
                        }

I beg you to ignore the "debugging" code

the thing is, as you see I did a setText on a TextView and the println's next to it confirm i have modified it. But the List is not updated and if I click on the same item again the change to "TRETA" is not there.

I tried to find a solution to this, I don't even know if it's possible to change the view while in the listener. Thanks in advance =)

P.S. the layout of the list item

this is kind of a bump. But I think I did a post a bit too much complicated... What I want is to when I click a list item, I want it to become grey or change its text.

I tried in the function of the onitemclicklistener and it doesn't change anything on the actual list.

thanks ^^
