android recyclerview constraintlayout kotlin

I need some guidance on I need help solving I'm facing an issue where I want to align the last item in my `RecyclerView` to the bottom of a `ConstraintLayout`, but it's not behaving as expected... I'm using Android 14 and the latest version of the AndroidX libraries. I have a `RecyclerView` that is supposed to fill the available space above a button at the bottom of the layout. I expected the last item in the `RecyclerView` to be aligned with the button, but instead, it seems to push the button upwards, causing it to overlap with other UI elements. Here is a simplified version of my layout: ```xml <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"> <androidx.recyclerview.widget.RecyclerView android:id="@+id/recyclerView" android:layout_width="0dp" android:layout_height="0dp" app:layout_constraintTop_toTopOf="parent" app:layout_constraintBottom_toTopOf="@+id/button" app:layout_constraintStart_toStartOf="parent" app:layout_constraintEnd_toEndOf="parent"/> <Button android:id="@+id/button" android:layout_width="wrap_content" android:layout_height="wrap_content" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" android:text="Submit"/> </androidx.constraintlayout.widget.ConstraintLayout> ``` I've tried setting the height of the `RecyclerView` to `0dp` to make it wrap its content, but it still doesn't align properly. I also ensured that my adapter is returning the correct item count, and I can see all my items rendered, but the last item seems to push the button up instead of aligning with it. I also checked the layout behavior in the RecyclerView and ensured that the layout manager is set correctly. I’m using `LinearLayoutManager` like this: ```kotlin val recyclerView: RecyclerView = findViewById(R.id.recyclerView) recyclerView.layoutManager = LinearLayoutManager(this) recyclerView.adapter = myAdapter ``` Is there something I might be missing, or is there a known issue with aligning RecyclerView items in ConstraintLayout in Android 14? Any help would be appreciated! This is for a desktop app running on Debian. This issue appeared after updating to Kotlin 3.9.
