thanks in advance!

the mainactivity.java:

you newbie, i'll try explain how sample project works. first of all, talk activity, need use fragment. activity host 1 or more fragments.

the activity diplays viewpager used display fragment (or view) , enable swiping 1 another. sectionspageradapter works adapter objects in android, create one, give data (ie : arraylist of country), implement methods including getview or in case getitem method. in these method given position in viewpager, can access right data , give fragment via bundle object (it's done in example, position +1).

to give data, use :

            visufragment fragment = new visufragment();             bundle args = new bundle();             args.putint("id", id);             fragment.setarguments(args);             return fragment; 

and oncreate method of fragment :

            int id = getarguments().getint("id"); 

the viewpager , adpater manage on screen, ask new fragment , delete old ones without knowing.

for sample code, if want see different on each page, delete content of oncreateview method , put :

            textview tv = new textview(getactivity().getapplicationcontext());             tv.settext("this fragment number : "+getarguments().getint(dummysectionfragment.arg_section_number);             return tv;
