public class TabsActivity extends AppCompatActivity {

    private Toolbar toolbar;
    private TabLayout tabLayout;

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tabs);

        setSupportActionBar(toolbar);


        viewPager = (ViewPager) findViewById(R.id.viewpager);

         * Initializing the viewpager with fragments
         */
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());


        adapter.addFragment(new TablesFragment(), "Progress");
        adapter.addFragment(MyFragment.newInstance("Example1"), "Example1");
        adapter.addFragment(MyFragment.newInstance("Example2"), "Example2");
        adapter.addFragment(MyFragment.newInstance("Example3"), "Example3");

        viewPager.setAdapter(adapter);

        tabLayout = (TabLayout) findViewById(R.id.tabs);

        //adding viewpager to the tablayout
        tabLayout.setupWithViewPager(viewPager);
        tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);

    class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List<Fragment> mFragmentList = new ArrayList<>();
        private final List<String> mFragmentTitleList = new ArrayList<>();

        public ViewPagerAdapter(FragmentManager manager) {
            super(manager);

            mFragmentList.add(fragment);
            mFragmentTitleList.add(title);
