This works perfectly, you will swipe between tabs:

MainActivity:

public class MainActivity extends FragmentActivity implements
    ActionBar.TabListener {
    CollectionPagerAdapter mCollectionPagerAdapter;
    ViewPager mViewPager;

    public void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);

           mCollectionPagerAdapter = new CollectionPagerAdapter(
           getSupportFragmentManager());

        final ActionBar actionBar = getActionBar();
        actionBar.setHomeButtonEnabled(false);
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
        mViewPager = (ViewPager) findViewById(R.id.pager);
        mViewPager.setAdapter(mCollectionPagerAdapter);
        mViewPager
        .setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {

            @Override

            public void onPageSelected(int position) {
                actionBar.setSelectedNavigationItem(position);
            }

        });
    for (int i = 0; i < mCollectionPagerAdapter.getCount(); i++) {
    actionBar.addTab(actionBar.newTab()
    .setText(mCollectionPagerAdapter.getPageTitle(i))
    .setTabListener(this));
    }

    }

    public void onTabUnselected(ActionBar.Tab tab,
    FragmentTransaction fragmentTransaction) {

    }

    public void onTabSelected(ActionBar.Tab tab,
    FragmentTransaction fragmentTransaction) {
    mViewPager.setCurrentItem(tab.getPosition());

    }

    public void onTabReselected(ActionBar.Tab tab,
    FragmentTransaction fragmentTransaction) {

    }

    public class CollectionPagerAdapter extends FragmentPagerAdapter {

    final int NUM_ITEMS = 3; // number of tabs

    public CollectionPagerAdapter(FragmentManager fm) {
    super(fm);

    }

    @Override

    public Fragment getItem(int i) {
    Fragment fragment = new TabFragment();
    Bundle args = new Bundle();
    args.putInt(TabFragment.ARG_OBJECT, i);
    fragment.setArguments(args);
    return fragment;

}

    @Override
    public int getCount() {

    return NUM_ITEMS;

}

    @Override
    public CharSequence getPageTitle(int position) {
    String tabLabel = null;
    switch (position) {
        case 0:
            tabLabel = getString(R.string.label1);
            break;
        case 1:
            tabLabel = getString(R.string.label2);
            break;
        case 2:
            tabLabel = getString(R.string.label3);
            break;

    }

    return tabLabel;

    }
    }

     public static class TabFragment extends Fragment {
     public static final String ARG_OBJECT = "object";

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

    Bundle args = getArguments();
    int position = args.getInt(ARG_OBJECT);
    int tabLayout = 0;
    switch (position) {
        case 0:
            tabLayout = R.layout.tab1;
            break;
        case 1:
            tabLayout = R.layout.tab2;
            break;
        case 2:
            tabLayout = R.layout.tab3;
            break;
    }

    View rootView = inflater.inflate(tabLayout, container, false);
    return rootView;

    }

   }

   }

activity_main:

<android.support.v4.view.ViewPager             xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"/>
