FrameLayout with Recyclerview

Question

I want to put the bottom navigation menu with my recyclerview at the bottom of the view. It is currently at the top and I need help sending it to the bottom.

This is how it look now:

This is my xml code:

<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">

<TextView
    android:id="@+id/titleTextView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginStart="20dp"
    android:layout_marginTop="20dp"
    android:text="Oficinas Credenciadas"
    android:textColor="@android:color/black"
    android:textSize="30sp"
    android:textStyle="bold"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/listRecyclerView"
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:layout_marginStart="1dp"
    android:layout_marginTop="8dp"
    android:layout_marginEnd="1dp"
    android:layout_marginBottom="1dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/titleTextView" />

<FrameLayout
    android:id="@+id/frame"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1"
    app:layout_constraintTop_toBottomOf="@+id/titleTextView"
    />

<com.google.android.material.bottomnavigation.BottomNavigationView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:menu="@menu/botton_nav_menu"
    tools:ignore="MissingConstraints" />

</androidx.constraintlayout.widget.ConstraintLayout>

I have made some changes and this is how it the items are positioned now.

This is how the code looks now. If this helps you, an upvote would be appreciated. Thanks

    <!-- NOT SURE WHY YOU HAVE THE FRAMELAYOUT AND RECYCLERVIEW OCCUPYING THE SAME SPACE BUT IF YOU INTEND TO HIDE AND SHOW THEM AT DIFFERENT TIMES, I HAVE IMPROVED THEIR CONSTRAINTS -->
