Below is the simple way to achieve your desired result

Add two (or equivalent to your tab actions) FloatingActionButton in your main activity like below

Now in your MainActivity.java use Fab's default functions to hide and show on each tab selection like below

private void animateFab(int position) {
    switch (position) {
        case 0:
            fabChat.show();
            fabPerson.hide();
            break;
        case 1:
            fabPerson.show();
            fabChat.hide();
            break;

        default:
            fabChat.show();
            fabPerson.hide();
            break;
    }
}

Call animateFab function as below

TabLayout.OnTabSelectedListener onTabSelectedListener = new TabLayout.OnTabSelectedListener() {
    @Override
    public void onTabSelected(TabLayout.Tab tab) {
        animateFab(tab.getPosition());
    }

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

    }

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

    }
};

ViewPager.OnPageChangeListener onPageChangeListener = new ViewPager.OnPageChangeListener() {
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int position) {
        animateFab(position);
    }

    @Override
    public void onPageScrollStateChanged(int state) {

    }
};
