ActionBar代码：

            actionBar.setHomeButtonEnabled(false);

            actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
 
 
        // Setting up the ViewPager rowingViewPager,attaching the RowingFragmentPagerAdapter and setting up a listener for when the
        // user swipes between sections.
            rowViewPager = (ViewPager) findViewById(R.id.pager);  
            rowViewPager.setAdapter(rowAdapter);

                new_tab.setTabListener(this);
                // Add tab with specified text as well as setting this activity as the TabListener.
                actionBar.addTab(new_tab);
 
 
            }
