In this video it shows the steps to make the constraint layout scrollable in both vertical and horizontal direction by adding ScrollView and HorizontalScrollView in your App’s constraint layout design respectively.
In this App it implements certain widgets in extreme bottom and right position in the layout to show the scrollable functionality of the layout. In the textView it uses layout_constraintVertical_chainStyle as “spread” to allow the textview to keep expanding in the bottom side to accommodate the long text within it.
