Answer 1

Did you use this?

// Setting the ViewPager For the SlidingTabsLayout
    tabs.setViewPager(pager);

Answer 2

You have to add this to change tabs with page and vice versa.

    viewPager.addOnPageChangeListener(newTabLayout.TabLayoutOnPageChangeListener(tabLayout));
    tabLayout.setTabsFromPagerAdapter(mAdapter);
