    Fragment fragmentTab2 = new FragmentTab2();
    Fragment fragmentTab3 = new FragmentTab3();

        // Create Actionbar Tabs
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        // Set Tab Icon and Titles
        AllTopics = actionBar.newTab().setIcon(R.drawable.tab1);
        NewContent = actionBar.newTab().setIcon(R.drawable.tab1);
        StaffPicks = actionBar.newTab().setIcon(R.drawable.tab1);
        Popular = actionBar.newTab().setIcon(R.drawable.tab1);
        Recommended = actionBar.newTab().setIcon(R.drawable.tab1);
        // Set Tab Listeners
        AllTopics.setTabListener(new TabListener(fragmentTab1));
        NewContent.setTabListener(new TabListener(fragmentTab2));
        StaffPicks.setTabListener(new TabListener(fragmentTab3));
        Popular.setTabListener(new TabListener(fragmentTab2));
        Recommended.setTabListener(new TabListener(fragmentTab2));

        // Add tabs to actionbar
        actionBar.addTab(AllTopics);
        actionBar.addTab(NewContent);
        actionBar.addTab(StaffPicks);
        actionBar.addTab(Popular);
        actionBar.addTab(Recommended);
        return rootView;
    }

}

Answer 1

That problem is that you are adding tabs constantly when you go back in your TopicsFragment which will call onCreateView again and executing the adding of tabs to the actionbar thus adding another set of tabs to the current tabs.

solution:

you need to check first if the number of tabs is zero in your actionbar.

sample:

actionBar.removeAllTabs();
if(actionBar.getTabCount() == 0)
    {
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        // Set Tab Icon and Titles
        AllTopics = actionBar.newTab().setIcon(R.drawable.tab1);
        NewContent = actionBar.newTab().setIcon(R.drawable.tab1);
        StaffPicks = actionBar.newTab().setIcon(R.drawable.tab1);
        Popular = actionBar.newTab().setIcon(R.drawable.tab1);
        Recommended = actionBar.newTab().setIcon(R.drawable.tab1);
        // Set Tab Listeners
        AllTopics.setTabListener(new TabListener(fragmentTab1));
        NewContent.setTabListener(new TabListener(fragmentTab2));
        StaffPicks.setTabListener(new TabListener(fragmentTab3));
        Popular.setTabListener(new TabListener(fragmentTab2));
        Recommended.setTabListener(new TabListener(fragmentTab2));

        // Add tabs to actionbar
        actionBar.addTab(AllTopics);
        actionBar.addTab(NewContent);
        actionBar.addTab(StaffPicks);
        actionBar.addTab(Popular);
        actionBar.addTab(Recommended);
    }
