I want to put this bottomnavigator with my recyclerview, and the bottom is only at the top of my code, I can't put it at the bottom.

I'm trying to get this data right for a project, and I really can't change

look how it is:

this is my xls:

<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"
    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> ```

Add

app:layout_constraintBottom_toBottomOf="parent"

To bottom navigation item so code will be like that

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

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
