I hava an ActionBar with tabs on it.

```
    actionBar = getActionBar();

    // Hide Actionbar Icon
    actionBar.setDisplayShowHomeEnabled(false);
    actionBar.setDisplayShowTitleEnabled(true);
   // Create Actionbar Tabs
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

    // Create first Tab
    tab = actionBar.newTab().setTabListener(new BusinessActivity());
    // Create your own custom icon
//    tab.setIcon(R.drawable.business);
    tab.setText("Business");
    actionBar.addTab(tab);

```

The BusinessActivity class in my example is extends Fragment.

**How can i change the ActionBar title when switching tabs?**

Thanks.
