Переопределить или добавить одну строку в пользовательском ListView

Я работаю над списком меню для приложения, которое я делаю. Я следовал этому руководству по его созданию (изменив значения по мере необходимости) - http://www.ezzylearning.com/tutorial.aspx?tid=1763429.

Теперь мой список не супер сложный. У него будут одни и те же данные каждый раз, и будет только два раздела. Пока мой список работает, но мне нужно заменить 7-й элемент другим представлением/макетом в xml или добавить это представление.

Текущий код....
