У меня есть проблема, чтобы изменить цвет фона GroupView на позиции.
Согласно моему кодексу
когда я нажимаю 1-й номер GroupView, то изменение цвета 1-го номера GroupView.
И
когда я нажимаю 2-й номер GroupView, то 1-й номер GroupView изменяется в цвете.
Я хочу изменить цвет GroupView в позиции Развернуть и свернуть.
