Android ViewPager2 Right to Left (RTL) Scroll (Reverse Scroll Direction)

ViewCompat.setLayoutDirection(viewPager, ViewCompat.LAYOUT_DIRECTION_RTL)

NOTE: Only supported on API 17 and above

via xml

<androidx.viewpager2.widget.ViewPager2
        android:layoutDirection="rtl"
        android:id="@+id/viewPager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

Edit AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <application
            ...
            android:supportsRtl="true">

    </application>
</manifest>

layoutDirection will cascade to all child views.

My purpose is not to implement RTL text display (I just wanted RTL scrolling), so I want want to reset layoutDirection in the child layout via android:layoutDirection="locale".
