android - Editing the current page on view pager -

i working on viewpager previous , next page. need increase text of current page, after loading page. while trying, text on next page changing (i know next , previous page load on viewpager). how can focused on 1 selected page? have done is,

viewpager.setclipchildren(false); 

unfortunately doesn't work..

i recommed using position parameter in activity , can update text based on position recieved.

this example fragments though

@override     public fragment getitem(int position) {         return pagefragment.newinstance(position);     } 

and in fragment recieve position argument:

public static pagefragment newinstance(int position) {     bundle args = new bundle();     args.putint("position", position);     pagefragment page = new pagefragment();     page.setarguments(args);     return page; } 

in oncreateview update textview based on position.

if want update textview this:

textview tv = (textview) view.findviewbyid(r.id.yourid); int position = getarguments().getint("position"); tv.settext("this page number: " + position);
