Good day. There is a new task. There is a catalog of masters. When you select a specific wizard, its page opens (activated with ViewPager), and now the wizards can be flipped through with a swipe. It all works. When trying to add a SlidingTabLayout wizard to the page, a strange thing began with page turning and displaying information: 1) The indicator slider stops somewhere between the tabs; 2) An unselected master is displayed, when turning the pages you can see that the selected master is not in the list of masters at all. I doubt that someone is now interested in watching the sources of what they dazzled up, I want a bit of theory. Has anyone come across SlidingTabLayout inside ViewPagera and, if so, please share your experience.
