ViewPagers | ViewPager widget | Widget library

I am using a ViewPager having 2 pages. First page of that ViewPager is MainFragment. MainFragment has ViewPager as bottomNavigationView. Each page has a FragmentContainerView and By default they contains HomeFragment, CommunityFragment and NotificationFragment respectively.

This is the Source Code and this is the APK of the project. So you can test it and improve it easily.

Now if i am in HomeFragment and I click on a profile button so It transact to ProfileFragment and from there setting and so on. And on clicking on back button it get back perfectly one-by-one. But it does not happens same with other FragmentContainerView. Even they get back directly to the parent fragment. Overall i am unable to handle the backstack between different ViewPagers and fragments.

To avoid the confusion of FragmentContainers i transact it like this

I'm trying to build an Android application using the new ViewPager2. I've added two ViewPagers, separated by a view, and when you swipe, both viewpagers should move. Both view pagers are moving correctly but upon completion of the gesture, the swiped view flashes and the non swiped view reloads, as demonstrated by the attached gif. Here is my code for the Activity, ViewPagerAdapter, and Fragment. Any help is appreciated

I have a DrawerLayout Activity with a Navigation View. The items are "Home", "About Us" "Events Schedule", etc. The Events Schedule has a fragment which contains a bottom navigation drawer and a view pager. There are only 2 fragments attached to the viewpager - Day 1 schedule and Day 2 schedule. Likewise, there is only 2 items in the bottom navigation. Each of these fragments has a recycler view where I display the list of events and their date & time.

When I launch the app, the home page fragment pops up as expected. I go to the navigation drawer and click on "Events Schedule". The recycler view loads the data. I can swipe on the view pager. Everything works fine.

But now when I click on "About us", that fragment opens up as usual. And when I reopen "Events and Schedule", the recycler view doesn't display any list items. It works for the first time I click it, but not the second, third and so on.

EventsFragment.kt (the main fragment with viewpager and bottom navigation):

I'm creating a host of a bunch of pages, and those pages are created dynamically. Each page has a function that I'd like to call at a specific time, but when trying to access a ref for the page, the current is always null.

I have setup ViewPager2 with TabLayout in order to switch fragments with a swipe or clicking on the tabs. The problem I have know is that my fragments are not taking all the space and I have an empty space at the bottom where I cannot swipe. How can I make my fragments to fill that space?

Edit: I think that my problem is related with the fact that I'm trying to load my viewpager inside another fragment. I copied my code into a new project and instead of loading my code into a fragment I loaded it into the main activity and It has worked. Is it a bad practice to load viewpagers inside a fragment?

I've changed my ProfileFragment.kt like this but it is still not working:

I have a ConstraintLayout that contains a ViewPager and another widget, we could call "A". I would want to add a constraint between one ViewPager's widget (we could call "B") and "A". B is, of course, a widget that is contained, in reality, in a fragment (because ViewPagers work with fragments). Note that this fragment's layout is a ConstraintLayout too.

The fact is that I can't do it using XML, if I have correctly understood what I read&tried.

So I have tried to do it programatically using this code:

I am following the MVVM pattern - meaning I have a ViewModel for each Fragment.

I added two tabs by using ViewPager2.

My adapter looks like this:

I couldn't get any idea or anything online so here I am. I'm using the jetpack navigation component and I want to navigate from fragmentA to fragmentB, and then fragmentB will have bottomnavigation with different fragments such as fragmentC, fragmentD, fragmentE, and fragmentE have viewpagers with different fragments such as fragmentF, fragmentG, fragmentH

I made an ImageAdapter class that contains images and an activity that contains 2 buttons, on click each one opens a new activity with a viewpager. The 2 viewpagers have different images and this is where my inexperience comes in.

I took the easy way and duplicated the ImageAdapter (named it ImageAdapter2) and linked it to the 2nd viewpager. visual representation

It works fine, but what I'm trying to do is clean it up and do it all through 1 adapter and 1 viewpager. I tried to do it through Intent getStringExtra but it didn't recognize Intent method. Here are my classes:

ImageAdapter (ImageAdapter2 is the same, just has different images in sliderImageId):
