TabLayout ViewPager2 work with Fragment how to make fragment init load when select Tab

Question

I have three Fragments

1. HomeFragment
2. DiscFrament
3. MeFragment

work with ViewPager2 and TabLayout set smoothScroll true use defalut, but lazy loading not working

 TabLayoutMediator(tabLayout, viewPager) {
     tab, position ->
        tab.text = position.toString() 
            }.attach()

and what I need is

1. I need smoothScroll the tab Indicator

2. Lazy loading Fragment when I scroll the page or Select Tab the Fragment data load view show

Answer 1

tabLayout.addOnTabSelectedListener(object: TabLayout.OnTabSelectedListener{
            override fun onTabSelected(tab: TabLayout.Tab?) {
                tab?:return
                viewPager.setCurrentItem(tab.position, false)
            }

            override fun onTabUnselected(tab: TabLayout.Tab?) {

            }

            override fun onTabReselected(tab: TabLayout.Tab?) {

            }

        })

the most important code is viewPager.setCurrentItem(tab.position, false) to override TabLayoutMediator addOnTabSelectedListener, so that it can be smooth scroll but also can lazy load
