Hello all, I’ve got one weird issue with

ViewPager2

and I cannot make any sense of it, I’ve got separate

Activity

that holds

ViewPager2

which contains fragments. That means destroying that activity with

finish()

closes

ViewPager2

as well. Now what I’ve got is beyond me, everything works fine when I start it for the first time, but if I close it and reopen my observables in the fragments won’t emit any changes, tho everything is created fine?. I’ve pinpointed issue to the

createFragment

method where commented part works but non commented doesn’t?

class PagerAdapter( 
    fragmentActivity: FragmentActivity,
    private val items: List<PagerAdapterFragment>
    //private val items: List<Int>
) : FragmentStateAdapter(fragmentActivity) {

    override fun createFragment(position: Int): Fragment {
        return items[position].fragment
//        return when (position) {
//            0 -> Fragment1.newInstance()
//            1 -> Fragment2.newInstance()
//            2 ->  PlaceholderFragment.newInstance("Retention information screen")
//            else ->  PlaceholderFragment.newInstance("Else")
//        }
    }

    data class PagerAdapterFragment(val id: Long, val fragment: Fragment)

You must always return a brand new Fragment instance from

createFragment

, that's why it is called create and not get

Hi @Ian Lake thanks for reply, that

get

was returning

newIstance()

of a Fragment. This is basically the same code, and when running the app Fragments were initialised properly, just for some reason observing wasn’t working.

Well, it very much looked like you were passing in a set of Fragment instances and calling

items[position].fragment

to return a previously created instance...not a brand new instance every single time

createFragment

was called
