Я хочу изменить вкладку, прокручивая экран. Я создаю вкладки, используя фрагмент tabhost, но когда я реализую функцию прокрутки в моем проекте, он не открывает вложенный фрагмент на каждой вкладке, потому что я открытие вложенного дочернего фрагмента внутри каждой вкладки.Как добавить жестов на фрагменте TAbHost
Пожалуйста, скажите мне, что это очень важно для меня.
вот мой код.
это мой основной деятельности.
