В onCreate вашей основной деятельности вы создаете и добавляете все вкладки (одна вкладка = 1 класс SherlockFragment).В вашей основной деятельности у вас должен быть внутренний класс, который является TabAdapter.В моем примере ниже, TabAdapter также ViewPager, так что вы можете провести в любом месте экрана, влево-вправо, чтобы переключаться между вкладками.Вот основной класс:

Вот фрагмент без какого-либо основного пользовательского интерфейса (только XML-файл с одним TextView в нем):
