How to start on middle tab when activity is called

Question

Can not figure out how to start on the middle tabs. here is test class for the fragment activity..any suggestions? I have three fragments, search, neweEntry, and editEntry. Hoping its a quick fix. thanks for your input.

private static final int ACTIVITY_CREATE=0;
private static final int ACTIVITY_EDIT=1;
private static final int actionCompose = Menu.FIRST;
private static final int DELETE_ID = Menu.FIRST + 1;


private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;

// Tab titles
private String[] tabs = { "search", "newEntry", "editEntry" };

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.test);



    // Initilization
    viewPager = (ViewPager) findViewById(R.id.pager);
    actionBar = getActionBar();
    mAdapter = new TabsPagerAdapter(getSupportFragmentManager());

    viewPager.setAdapter(mAdapter);
    actionBar.setHomeButtonEnabled(false);
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);


    // Adding Tabs
    for (String tab_name : tabs) {
        actionBar.addTab(actionBar.newTab().setText(tab_name)
                .setTabListener(this));

    }

    /**
     * on swiping the viewpager make respective tab selected
     * */
    viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

        @Override
        public void onPageSelected(int position) {
            // on changing the page

            // make respected tab selected
            actionBar.setSelectedNavigationItem(position);
        }

        @Override
        public void onPageScrolled(int arg0, float arg1, int arg2) {
        }

        @Override
        public void onPageScrollStateChanged(int arg0) {
        }
    });
}

@Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}

@Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
    // on tab selected
    // show respected fragment view
    viewPager.setCurrentItem(tab.getPosition());
}

@Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu items for use in the action bar
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main, menu);
    // android.R.id.content as the container for each fragment

    // setup action bar for tabs
    ActionBar actionBar = getActionBar();
    actionBar.setDisplayShowTitleEnabled(false);

    return super.onCreateOptionsMenu(menu);
}

  @Override
    public boolean onMenuItemSelected(int featureId, MenuItem item) {
        switch(item.getItemId()) {
            case actionCompose:
                createNote();
                return true;

            case R.id.actionCompose:
                createNote();
                return true;

       }

        return super.onMenuItemSelected(featureId, item);
    }

  private void createNote() {
        Intent i = new Intent(this, editActivity.class);
        startActivityForResult(i, ACTIVITY_CREATE);
    }
}

In your onCreate method, you can set the default navigation tab by doing something like this:

actionBar.setSelectedNavigationItem(your_fragment_position);
