What i am doing:: I am trying to display a tabbed viewpager

MainActivity.java

public class MainActivity extends FragmentActivity implements TabListener  {

    ViewPager viewPager;
    ActionBar actionBar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Set the view from main_fragment.xml

        requestWindowFeature(Window.FEATURE_ACTION_BAR);
        setContentView(R.layout.main_activity);

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

        viewPager.setAdapter(new MyAdapter(getSupportFragmentManager()));


        actionBar = getActionBar();
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        ActionBar.Tab tab1=actionBar.newTab();
        tab1.setText("Tab1");
        tab1.setTabListener(this);

        ActionBar.Tab tab2=actionBar.newTab();
        tab2.setText("Tab2");
        tab2.setTabListener(this);

        ActionBar.Tab tab3=actionBar.newTab();
        tab3.setText("Tab3");
        tab3.setTabListener(this);

        actionBar.addTab(tab1);
        actionBar.addTab(tab2);
        actionBar.addTab(tab3);

    }


    @Override
    protected void onDestroy() {
        Log.d(getClass().getName(), "[onDestroy(activity)]");
        super.onDestroy();
    }


    @Override
    public void onTabReselected(Tab arg0, android.app.FragmentTransaction arg1) {
        // TODO Auto-generated method stub

    }


    @Override
    public void onTabSelected(Tab arg0, android.app.FragmentTransaction arg1) {
        // TODO Auto-generated method stub

        viewPager.setCurrentItem(arg0.getPosition());
    }


    @Override
    public void onTabUnselected(Tab arg0, android.app.FragmentTransaction arg1) {
        // TODO Auto-generated method stub

    }

}


class MyAdapter extends FragmentPagerAdapter
{

    public MyAdapter(FragmentManager fm) {
        super(fm);
        // TODO Auto-generated constructor stub
    }

    @Override
    public Fragment getItem(int arg0) {
        // TODO Auto-generated method stub

        Fragment fragment=null;
        if(arg0==1){
            fragment=new SortRestaurantFragment();
        }
        if(arg0==2){
            fragment=new SortRestaurantFragment();

        }
        if(arg0==3){
            fragment=new SortRestaurantFragment();

        }
        return fragment;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return 3;
    }

}

main_activity.xml

<android.suppoort.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

I have also added the support libraries::
