How to set guidelines to the original screen size inside scrollview

Question

I just started app development trying to make an e-commerce app since using fragments is a better way rather than activities I made a home page inside which I want to show first the action bar then top-selling (top-4 selling products) and after that all the products.

this is some i want to achieve image

I am using guideline to constraint view pager to limited section but since its a fragment its not scrollable so i have to set it to scrollable but the second I set it to scroll view the size of screen increase and the view pager gets distorted.

code of my home fragment without scroll view

try using LinearLayout inside scrollView(Copy and paste)

<FrameLayout 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">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <ScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical">

                <include
                    android:id="@+id/home_actionbar"
                    layout="@layout/actionbar"
                    app:layout_constraintEnd_toEndOf="parent"
                    app:layout_constraintStart_toStartOf="parent"
                    app:layout_constraintTop_toTopOf="parent" />

                <com.google.android.material.textview.MaterialTextView
                    android:id="@+id/top_selling_heading"

                <TextView
                    android:id="@+id/product_heading"
                    android:layout_width="wrap_content"

                    app:layout_constraintEnd_toEndOf="@id/top_selling_heading"
                    app:layout_constraintStart_toStartOf="@id/top_selling_heading"
                    app:layout_constraintTop_toBottomOf="@id/guideline2" />

                <androidx.recyclerview.widget.RecyclerView
                    android:id="@+id/productRV"
                    android:layout_width="0dp"
                    android:layout_height="wrap_content"
                    android:layout_margin="10sp"
                    android:scrollbars="vertical"
                    app:layout_constraintEnd_toEndOf="parent"
                    app:layout_constraintStart_toStartOf="parent"
                    app:layout_constraintTop_toBottomOf="@id/product_heading"
                    tools:listitem="@layout/product_item" />

            </LinearLayout>


        </ScrollView>


    </LinearLayout>
</FrameLayout>

as you can see my view pager is attached to the guideline and since it's a linear layout guideline doesn't work — Anmol Sethi, Dec 12 '22 at 07:36
