Pourquoi ma liste n'est-elle pas rafraîchissante?

Question

J'ai une liste de fichiers et quand l'utilisateur enregistre un fichier, je veux rafraîchir la liste pour que le nouveau fichier apparaisse. C'est ce que j'ai essayé.

private IconifiedTextListAdapter itla = new IconifiedTextListAdapter(this); 

...

private void saveAs(){ 
       AlertDialog.Builder alert = new AlertDialog.Builder(this); 

       alert.setTitle("Save as"); 
       alert.setMessage("(Will be saved in the current working directory)"); 

       // Set an EditText view to get user input 
       final EditText input = new EditText(this); 
       alert.setView(input); 

       alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface dialog, int whichButton) { 
        String value = input.getText().toString(); 
        String tmpText = et.getText().toString(); 

        try { 
        File tempfile = new File(currentDirectory, value); 
        FileWriter writer = new FileWriter(tempfile); 
         writer.write(tmpText); 
         writer.flush(); 
         writer.close(); 
         changed=false; 
         itla.notifyDataSetChanged(); 
       } catch (IOException e) { 
        // TODO Auto-generated catch block 
       e.printStackTrace(); 
       } 
        } 
       });
