Try this,

  tabs.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
            @Override
            public void onTabSelected(TabLayout.Tab tab) {
                Toast.makeText(mActivity, "hai", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onTabUnselected(TabLayout.Tab tab) {

            }

            @Override
            public void onTabReselected(TabLayout.Tab tab) {

            }
        });

In Kotlin,

tabs.addOnTabSelectedListener(object:TabLayout.OnTabSelectedListener {
    override fun onTabSelected(tab : TabLayout.Tab) {
        Toast.makeText(mActivity, tab.text, Toast.LENGTH_SHORT).show()
    }
    override fun onTabUnselected(p0: TabLayout.Tab?) {

    }
    override fun onTabReselected(p0: TabLayout.Tab?) {

    }
})
