Question

My ActionBar tabs are disappearing when I start an activity from them. I can see the Activity all right, but the tabs don’t appear.

My SherlockFragmentActivity is –

public class FragmentDemoActivity extends SherlockFragmentActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ActionBar bar = getSupportActionBar();
    bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
    ActionBar.Tab tab1 = bar.newTab();
    ActionBar.Tab tab2 = bar.newTab();

    tab1.setText("Fragment A");
    tab2.setText("Fragment B");

    tab1.setTabListener(new MyTabListener());
    tab2.setTabListener(new MyTabListener());
    bar.addTab(tab1);
    bar.addTab(tab2);
}

private class MyTabListener implements ActionBar.TabListener
{

    @Override
    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        if(tab.getPosition()==0)
        {
            CalendarViewActivity frag = new CalendarViewActivity();
            startActivity(new Intent(getApplicationContext(),CalendarViewActivity.class));
            //ft.replace(android.R.id.content, frag);

        }
        else
        {
            TestActivity frag = new TestActivity();
            //ft.replace(android.R.id.content, frag);
        }
    }

    @Override
    public void onTabUnselected(Tab tab, FragmentTransaction ft) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onTabReselected(Tab tab, FragmentTransaction ft) {
        // TODO Auto-generated method stub

    }

}

}

While my Acitivity is a normal Android Activity –

public class CalendarViewActivity extends Activity

Any help please.

Of course not. You did not put any tabs on CalendarViewActivity, in part because CalendarViewActivity is just a regular Activity.

If you are thinking that tapping on a tab should load something into FragmentDemoActivity, then you should not be calling startActivity() from your TabListener. Instead, you should be executing a FragmentTransaction or otherwise modifying the UI of FragmentDemoActivity.
