隐藏/显示动作栏标签

Question

Upon install, my app would show only 1 tab, hence I want to hide the tab row.

When user login/signup, additional tabs would show up.

I create tabs(fragments) in onCreate().

   @Override
    public void onResume() {
        super.onResume();
        this.supportInvalidateOptionsMenu();

        if(logged_in()){
            m_actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
            m_actionBar.setSelectedNavigationItem(this.m_previousTabIndex);
        }
        else
            m_actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);

        return;
    }

I don't see the tabs.. that's good.
But I don't see the first tab's contents either. I don't see nothing but actionBar in screen.
How do I fix this to show the first tab's contents?

我将看一下ActionBarSherlock示例，以了解它们如何工作。
