Я создаю приложение, в котором будет показан список отелей, все данные поступают из MySQL с помощью JSON и PHP , Я создал обычай list view
, расширив базовый адаптер до пользовательского, но я не могу реализовать OnItemClickListener
для listview
, так как я хочу показать название отеля этой строки в Toast
всякий раз, когда пользователь нажимает на строку Посмотреть список. Я пробовал использовать различные примеры в Интернете, но я просто не работаю.Как создать OnItemClickListener для просмотра пользовательского списка при передаче данных из PHP с помощью JSON
