Displaying the button in recycler view with distance feature

Question

I want to make a feature like in the attached image. It will display a button on top of the recycler view with a distance of the items in the recycler view. As the user will scroll down it will show items that are far away from the user location. However, I do not know how to implement this type of button that overlaps the recycler view. Can anyone let me know please what is this feature known as? How can I search more about it. I have tried searching with "button overlaps recycler view" but nothing found that can help. Any help will be appreciated. Thanks

This is called Extended Floating Action Button, what you could do is something like this :

<?xml version="1.0" encoding="utf-8"?>
<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"
    xmlns:tools="http://schemas.android.com/tools"
    >

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        tools:listitem="@android:layout/simple_list_item_checked"
        />

    <com.google.android.material.floatingactionbutton.ExtendedFloatingActionButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Displaying items 250 to 500 miles from you"
        android:layout_marginTop="16dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        />

</androidx.constraintlayout.widget.ConstraintLayout>

The output is :
