问题 I am writing application that uses ViewPager to host Fragment s. When I change fragment programmatically the smooth scroll function does not work. I use ViewPager.setCurrentItem(int item, boolean smoothScroll)` method. Maybe anyone know a workaround this bug? Maybe with animations? EDIT: I am using support package.
