在我的布局中有回收站视图和底部导航栏，但导航栏位于回收站视图后面

Question

In my layout there is recyclerview and bottom navigation bar but the problem is that the recyclerview occupies all the view and the bottom navigation bar and the header bad goes behind the recycler view. I've sucessfully implemented the material dependency.

this is the layout:

This is the code of the layout.

Try this by giving specific height to the BottomAppBar. Then provide margin top and Bottom to the RelativeLayout :

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout 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:id="@+id/baseLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <!--status bar-->
    <com.google.android.material.bottomappbar.BottomAppBar
        android:id="@+id/default_activity_button"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:layout_gravity="top"
        android:backgroundTint="@color/buttoncolor"
        app:menu="@menu/default_menu" />

    <!--add button-->
    <com.google.android.material.bottomappbar.BottomAppBar
        android:id="@+id/bottomAppBar"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:layout_gravity="bottom"
        android:backgroundTint="@color/buttoncolor"
        app:fabAlignmentMode="end"
        app:fabCradleMargin="6.2sp"
        app:fabCradleRoundedCornerRadius="15sp"
        app:menu="@menu/app_bar_menu" />


    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:backgroundTint="#ED4444"
        android:onClick="openCamera"
        android:src="@drawable/ic_add"
        app:layout_anchor="@id/bottomAppBar"

        app:maxImageSize="35sp"
        app:tint="@color/white" />


    <RelativeLayout
        android:layout_marginTop="50dp"
        android:layout_marginBottom="50dp"

            android:layout_below="@+id/empty_list" />

        <LinearLayout
            android:id="@+id/empty_list"
            android:visibility="gone"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center_vertical|center_horizontal"
            android:orientation="vertical">

            <ImageView

                android:layout_height="200dp"
                android:background="@drawable/ic_no_data" />

            <TextView

                android:layout_width="match_parent"

                android:textStyle="bold"
                android:text="Scan the files"
                android:paddingLeft="20dp"
                android:paddingRight="20dp"
                android:textSize="24dp"
                android:gravity="center_horizontal"/>

            <TextView

        </LinearLayout>


    </RelativeLayout>
