You can use addOnTabSelectedListener method:

tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            viewPager.setCurrentItem(tab.getPosition());
            if (tab.getPosition() == 0) {
                toolBarTitle.setText("Tab one");
            } else if (tab.getPosition() == 1) {
                toolBarTitle.setText("Tab two");
            } else {
                toolBarTitle.setText("Tab three");
            }
        }

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

        }

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

        }
    });
