Used xml file like this:

and your java file is here:

public class MyFragment extends Fragment {

    private View view;
    private TabLayout tabLayout;

    //This is our viewPager
    private ViewPager viewPager;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        view = inflater.inflate(R.layout.sticker_fragment, container, false);

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

        viewPager = (ViewPager) view.findViewById(R.id.pager);

        Viewpager adapter = new Viewpager(getActivity().getSupportFragmentManager(), getActivity());

        //Adding adapter to pager
        viewPager.setAdapter(adapter);


        tabLayout.setupWithViewPager(viewPager);
        tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
            @Override
            public void onTabSelected(TabLayout.Tab tab) {
                viewPager.setCurrentItem(tab.getPosition());
            }

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

            }

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

            }

            });

        return view;
    }



}

after that viewpager adapter is like this:

public class Viewpager extends FragmentStatePagerAdapter {

    final int PAGE_COUNT = 2;
    private String tabTitles[] = new String[]{"Local","Online"};
    private Context context;

    public Viewpager(FragmentManager fm, Context context) {
        super(fm);
        this.context = context;
    }

    @Override
    public Fragment getItem(int position) {
        switch (position){
            case 0:
                OneFragment oneFragment=new OneFragment();
                return oneFragment;
            case 1:
                TwoFragment twoFragment=new TwoFragment();
                return twoFragment;
            default:
                return null;
        }
    }

    @Override
    public int getCount() {
        return tabTitles.length;
    }

    @Override
    public CharSequence getPageTitle(int position) {

        return tabTitles[position];
    }

}
