Cannot move TextView that is constraint to RecyclerView when RecyclerView items are dissapearing

Question

I have 2 recycler views and one text view. What I am trying to do is when I click from top recyclerview(recyclerViewNotClickedItems) the items, they will disappear and they will appear in the bottom recyclerview(recyclerViewClickedItems).

My problem is that the TextView I have, I want it to go more up and up as I am clicking items from first recyclerview and they dissapear , and in the end since there are no items, the text view should be on the top of the screen.

Here is my code:

<RecyclerView
    android:id="@+id/recyclerViewNotClickedItems"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    app:layout_constraintTop_toTopOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintBottom_toTopOf="@+id/settingsYouAlreadySeeTxt" />

<TextView
    android:id="@+id/settingsYouAlreadySeeTxt"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/settings_you_already_seen"
    android:textSize="40sp"
    android:visibility="invisible"
    app:layout_constraintStart_toStartOf="@+id/recyclerViewNotClickedItems"
    app:layout_constraintTop_toBottomOf="@+id/recyclerViewNotClickedItems">

</TextView>

<RecyclerView
    android:id="@+id/recyclerViewClickedItems"
    android:layout_width="0dp"
    android:layout_height="0dp"
    app:layout_constraintTop_toBottomOf="@+id/settingsYouAlreadySeeTxt"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintBottom_toBottomOf="parent" />

And here is the implemented logic

 adapterCheckedList = RecyclerViewListAdapter()
 adapterNotCheckedList = RecyclerViewListAdapter(clickListener = { view: View, listItem: Any, position: Int ->
            binding.settingsYouAlreadySeeTxt.visibility = View.VISIBLE //Here, besides visibility i want to move it to the top everytime unCheckedList gets smaller.
            val removedItem =unCheckedList.removeAt(position)
            checkedList.add(removedItem)

            adapterNotCheckedList.submitList(unCheckedList)
            adapterCheckedList.submitList(removedItem)
        })

Let RecyclerView handle views ,you only handle data and then notice recyclerview data are changed.

adapterNotCheckedList = RecyclerViewListAdapter(clickListener = { view: View, listItem: Any, position: Int ->
    //Here, besides visibility i want to move it to the top everytime unCheckedList gets smaller.
    checkedList.add(unCheckedList.removeAt(position))
    // you need get adapter.
    topAdapter.notifyItemRemoved(position)
    bottomAdapter.notifyItemInserted(checkedList.lastIndex)
})

if unchecked list is too large ,you will only see top recyclerview.

you can update you xml like
<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RecyclerView
        android:id="@+id/recyclerViewNotClickedItems"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent" />

    <TextView
        android:id="@+id/settingsYouAlreadySeeTxt"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/settings_you_already_seen"
        android:textSize="40sp"
        android:visibility="invisible"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toBottomOf="@id/recyclerViewNotClickedItems"
        app:layout_constraintBottom_toTopOf="@id/recyclerViewClickedItems" />

    <RecyclerView
        android:id="@+id/recyclerViewClickedItems"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintTop_toBottomOf="@id/settingsYouAlreadySeeTxt"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintBottom_toBottomOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>
