you can try -
@override public object instantiateitem(viewgroup container, int position) { layoutinflater inflater; if(position != 10){ inflater = (layoutinflater) context .getsystemservice(context.layout_inflater_service); itemview = inflater.inflate(r.layout.viewpager_item, container, false); itemview.settag("view"+position); } else { inflater = (layoutinflater) context .getsystemservice(context.layout_inflater_service); itemview = inflater.inflate(r.layout.results, container, false); } container.addview(itemview); return itemview ; } and when need current view-
view myview = pager.findviewwithtag("view"+pager.getcurrentitem());
