you need to use suitable constraint layouts and tab layouts as per android X that's it!
for example :

<androidx.constraintlayout.widget.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="#ffffff"
    tools:context=".Activities.OnboardingActivity">
 .
 .
 .
 .
</androidx.constraintlayout.widget.ConstraintLayout>
