resource page2 page3

use startactivity open other activities, requires basic intent

sp.setonitemselectedlistener(new onitemselectedlistener() {     @override     public void onitemselected(adapterview<?> parent, view view, int position, long id)     {         string s=((textview)arg1).gettext().tostring();          if(s.equals("page2"))             startactivity(new intent(view.getcontext(), appactivity2.class));          if(s.equals("page3"))             startactivity(new intent(view.getcontext(), appactivity3.class));     } }); 

you're array in resources may not set correctly.

it should similar this:

<string-array name="spinnervalue">     <item>page2</item>     <item>page3</item> </string-array>
