BottomNavigationView 被放置在父级之上

Question

Im using BottomNavigationView built into AndroidStudio and im trying to place this on the bottom of the parent. I am using layout_gravity="bottom", but it still gets moved to the top. Any ideas on what im doing wrong?

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <RelativeLayout
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:layout_marginStart="10dp"
        android:layout_marginTop="10dp">


        <de.hdodenhof.circleimageview.CircleImageView
            android:id="@+id/profile_image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/profil"/>


    </RelativeLayout>

    <com.google.android.material.bottomnavigation.BottomNavigationView
        android:id="@+id/bottom_navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="@android:color/holo_green_dark"
        app:itemIconTint="@android:color/white"
        app:itemTextColor="@android:color/white"
        app:menu="@menu/bottom_menu" />

</LinearLayout>

As I said in the comments, an alternative is to use ConstraintLayout

<?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:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <RelativeLayout
        android:id="@+id/relativeLayout"
        android:layout_width="40dp"
        android:layout_height="0dp"
        android:layout_marginStart="10dp"
        android:layout_marginTop="10dp"
        app:layout_constraintBottom_toTopOf="@+id/bottom_navigation"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">
        
        <de.hdodenhof.circleimageview.CircleImageView
            android:id="@+id/profile_image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/profil" />

    </RelativeLayout>

    <com.google.android.material.bottomnavigation.BottomNavigationView
        android:id="@+id/bottom_navigation"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:background="@android:color/holo_green_dark"
        app:itemIconTint="@android:color/white"
        app:itemTextColor="@android:color/white"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/relativeLayout"
        app:menu="@menu/bottom_menu" />

</androidx.constraintlayout.widget.ConstraintLayout>
