Я создал настраиваемую панель поиска диапазона и хотел бы реализовать для нее специальные возможности.Обычный жест для перемещения мяча вправо / вверх в строке поиска по умолчанию - «Вправо, затем влево».Поэтому, когда пользователь фокусируется на левом шаре, я хочу обнаружить жест «Вправо, затем налево», когда включен режим обратной связи, и переместить мяч на один шаг.
Вы можете активировать функцию обратной связи и использовать громкость какпример того, чего я пытаюсь достичь.
Информация о жестах обратного вызова: URL
