Its a bug with ActionBarSherlock (from https://github.com/JakeWharton/ActionBarSherlock/issues/327 ).
Cause:
When you call setDisplayShowHomeEnabled (false) in onCreate () and using the tab navigation mode, tabs will appear above the action bar, unlike below.
:
setDisplayShowHomeEnabled :
View homeIcon = findViewById(android.R.id.home);
((View) homeIcon.getParent()).setVisibility(View.GONE);
