                    break;
                case 1:
                    tvStateReservation.setText("Sur place");
                    break;
                case 2:
                    tvStateReservation.setText("À emporter");
                    break;
            }

        }

    }

}

The problem is in the method called test10 Where I check the size of the list of tags from the object in the list of objects, to make textviews appear and show the corresponding tags

It works, but when I go through the whole list, I scroll downwards, when I return, tags that should not go in which already showed well appear, the correct tags appear and 1 tag that should not go.

For example, in the restaurant were the Italian and Pizza tags, when climbing Italian, pizza and traditional appears

Alado was a Japanese restaurant, before he said Japanese, now he says, Japanese and pizza.
