Почему мой CustomAdapter не используется?

Я создал класс под названием FTPSite с геттерами и сеттерами для имени, адреса, имени пользователя, пароля, порта, пассивного режима. Я пытаюсь создать менеджер сайта, используя пользовательский адаптер, чтобы показывать имена сайтов, но я просто получаю имя и номера пакетов в качестве элемента списка.Почему мой CustomAdapter не используется?

заменить SiteAdapter adapter;

ArrayAdapter<FTPSite> adapter

затем в классе адаптера необходимо создать конструктор, как это

public SiteAdapter(Context context, int resource, int textViewResourceId, List<T> objects) { 
    super(context,resource,textViewResourceId,objects); 
}

см documentation

EDIT:

когда вы объявляете, что нужно сделать

adapter = new SiteAdapter(this,r.layout.your_layout,new int[] {r.id.title},model);

См. Мое редактирование. Я внес изменения, но я не вижу никакой разницы. – RapsFan1981

нет, вы не внесли изменений. Если вы объявляете свой адаптер как переменную класса с адаптером SiteAdapter, это неверно. он должен быть «ArrayAdapter adapter' – tyczj

О, извините, я не сохранил изменения, позвольте мне сделать это снова – RapsFan1981

Почему мой CustomAdapter не используется?
