How to include an outer XML layout in Android

Question

We are re-designing our Android app and I have created the basic layout in a XML file. I am planning to re-use the same layout in multiple activities but I'm not sure how to include this in a new activity and change just the inner contents (inside the NestedScrollView)? I'll be using this layout in different journeys so can't change those to one-activity and multiple fragments? Is there a clever way of including the base outer layout and change the inner contents in XML? Thanks

Base layout:

<?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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@color/grey_10">

<com.google.android.material.appbar.AppBarLayout
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    android:background="@color/grey_10">

    <include
        android:id="@+id/options_toolbar"
        layout="@layout/toolbar_simple"
        app:layout_scrollFlags="scroll|enterAlways|snap"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

</com.google.android.material.appbar.AppBarLayout>

<androidx.core.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <androidx.constraintlayout.widget.ConstraintLayout
        android:id="@+id/container_modes"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/grey_10"
        android:paddingTop="@dimen/journey_planner_top_padding">

        <TextView
            android:id="@+id/description"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            android:paddingTop="12dp"
            android:paddingBottom="24dp"
            android:paddingStart="30dp"
            android:paddingEnd="30dp"
            android:textSize="16sp"
            app:fontFamily="@font/johnston100_light"
            android:textColor="@color/johnstonBlack"
            android:text="Text"/>

    </androidx.constraintlayout.widget.ConstraintLayout>

</androidx.core.widget.NestedScrollView>

</androidx.coordinatorlayout.widget.CoordinatorLayout>
