Создаю приложение Anekdot Reader: http://4pda.ru/forum/index.php?showtopic=334581
Дело в том, что анекдоты выводятся в TextView (id=text), а этот TextView находится в ScrollView. Мне необходимо одновременно обрабатывать TouchListener (для слайда вперед - назад) и ScrollView (вверх - вниз), как мне это осуществить?
Вот layout единственного Activity:
