you can add a listener to viewpager and show and hide fab according to its state when you start scrolling the viewpager this is the order of states SCROLL_STATE_DRAGGING SCROLL_STATE_SETTLING SCROLL_STATE_IDLE

viewPager.addOnPageChangeListener(this);
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
    }

    @Override
    public void onPageSelected(int position) {

    }

    @Override
    public void onPageScrollStateChanged(int state) {
        if(state==ViewPager.SCROLL_STATE_IDLE)
            fab.show();
        else if(state==ViewPager.SCROLL_STATE_DRAGGING)
            fab.hide();

    }
