I have used Jake Wharton library for building viewpager with TabPageInicator , i have 7 tabs but i want 4 tabs to be viable and user can swipe to show other tabs , how can i do that?

    ViewPager pager = ( ViewPager ) getActivity().findViewById( R.id.pager ) ;
    pager.setAdapter( adapter ) ;

    TabPageIndicator indicator = ( TabPageIndicator ) getActivity().findViewById( R.id.indicator ) ;
    indicator.setViewPager( pager ) ;
