How can I put a Webview below other views and scroll all views together

I'm developing an android application there I have a webview below other views.

The whole content does not fit the screen so I want to enable some scrolling.

My layout file looks like this:

<android.support.constraint.ConstraintLayout
    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"
    android:background="@color/white"
    tools:layout_editor_absoluteX="8dp"
    tools:layout_editor_absoluteY="8dp">

    <TextView .../>
    <TextView .../>
    <TextView .../>
    <TextView .../>

    <WebView
        android:id="@+id/about_detail"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="24dp"
        android:textSize="14sp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/contactInformation"
        tools:layout_constraintLeft_creator="1"
        tools:layout_constraintRight_creator="1"
        tools:layout_constraintTop_creator="1" />

</android.support.constraint.ConstraintLayout>

Should I use a Scrollview around my ConstraintLayout, or how can I do that?
