public class MainActivity extends  AppCompatActivity{

  private Toolbar toolbar;
    private TabLayout tabLayout;
    private ViewPagerAdapter adapter;

    private final static int[] tabIcons = {
            R.drawable.ic_action_car,
            android.R.drawable.ic_menu_mapmode,
            android.R.drawable.ic_dialog_email,
            R.drawable.ic_action_settings
    };

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
            Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
       setSupportActionBar(toolbar);

        ViewPager viewPager = (ViewPager)         findViewById(R.id.container);
        setupViewPager(viewPager);


        tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(viewPager);
        setupTabIcons();

        
        }
            private void setupTabIcons() {
        tabLayout.getTabAt(0).setIcon(tabIcons[0]);
        tabLayout.getTabAt(1).setIcon(tabIcons[1]);
        tabLayout.getTabAt(2).setIcon(tabIcons[2]);
        tabLayout.getTabAt(3).setIcon(tabIcons[3]);
    }

    private void setupViewPager(ViewPager viewPager) {
        adapter = new ViewPagerAdapter(getSupportFragmentManager());
        adapter.addFrag(new CarFragment());
        adapter.addFrag(new LocationFragment());
        adapter.addFrag(new MessageFragment());
        adapter.addFrag(new SettingsFragment());
        viewPager.setAdapter(adapter);
    }
    
    class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List mFragmentList = new ArrayList<>();
        ViewPagerAdapter(FragmentManager manager) {
            super(manager);
        }

        @Override
        public Fragment getItem(int position) {
            return mFragmentList.get(position);
        }

        @Override
        public int getCount() {
            return mFragmentList.size();
        }

        void addFrag(Fragment fragment) {
            mFragmentList.add(fragment);

        }

    }
        }
