Italian Elementi numerosi

Ciao a tutti,

se stampo una lunga listview che non ci sta dentro lo schermo posso scorrerla verso il basso con questa istruzione "lstCategorie.FastScrollEnabled = True" ma se dopo la lista devo aggiungere altri elementi quali bottoni e label posso scorrere tutto lo schermo verso il bass? premetto che non riesco ad usare le scrollView, e che devo caricare e stampare i dati in modo dinamico, quindi le dimensioni della lista non sono fisse... Grazie e ciao
