With this piece of code
final ListView lw = (ListView) findViewById( R.id.book_list );
lw.setVisibility(View.VISIBLE);
ListView listBookView = (ListView) findViewById( R.id.book_list );
ArrayList<HashMap<String, Object>> my_list = new ArrayList<HashMap<String, Object>>();
for ( int x=0; x< book_list.size(); x++)
{
String[] valori_book = book_list.get( x ).getObjVars();
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("book", valori_book[ 0 ]);
map.put("descr", valori_book[ 1 ] );
my_list.add(map);
}
// ...
SimpleAdapter showMenu = new SimpleAdapter(this, my_list, R.layout.activity_book_booklistmask,
new String[] { "book" , "descr" }, new int[] {R.id.nome_quaderno, R.id.descrizione_quaderno});
listBookView.setAdapter(showMenu);

From the SimpleAdapter documentation
A view that implements Checkable (e.g. CheckBox). The expected bind value is a boolean.
TextView. The expected bind value is a string and setViewText(TextView, String) is invoked.
ImageView. The expected bind value is a resource id or a string and setViewImage(ImageView, int) or setViewImage(ImageView, String) is invoked.
It would appear that passing an Object as the mapped object is not compatible with SimpleAdapter. Change the object type, or create a custom adapter (I recommend the later)
