Best practices is used material TabLayout with ViewPager2.

dependencies {
    // ...
    implementation 'com.google.android.material:material:1.0.0'

}

In XML attributes

In Kotlin

//set your adapter
//view_pager.adapter =  WebViewFragmentTabAdapter(supportFragmentManager, lifecycle)
TabLayoutMediator(tab_layout, view_pager) { tab, position ->
    tab.text = AppDataInstance.navigationTab[position].name
    view_pager.setCurrentItem(tab.position, true)
}.attach()

// in case you need to set color programmatically
(tab_layout as TabLayout).setBackgroundColor(ContextCompat.getColor(mContext, R.color.colorPrimary))
(tab_layout as TabLayout).setSelectedTabIndicatorColor(ContextCompat.getColor(mContext, R.color.white))
(tab_layout as TabLayout).setTabTextColors(ContextCompat.getColor(mContext, R.color.white),
                ContextCompat.getColor(mContext, R.color.white))
