java - ViewPager not responding quickly -

while using viewpager noticed wouldn't respond quickly, meaning slows down when switchting through fragments, kind of in laggy way. does know how code causing issue?

public class list_adapter : baseadapter<element> {     public list<element> _list;      fragmentone _context;       public list_adapter(fragmentone context, list<element> list)      {                                                      super(context, list);                              _list = list;         _context = context;     }     @override     public int getcount()      {         return _list.size();     }     @override     public object getitem(int position)      {         return _list.get(position);     }     @override     public long getitemid(int position)      {         return getitem(position).hashcode();     }     @override     public view getview(int position, view convertview, viewgroup parent)      {         layoutinflater inflater = (layoutinflater)getactivity().getapplicationcontext().getsystemservice(context.layout_inflater_service);         view view = inflater.inflate(r.layout.row, parent, false);          element item = getitem(position);         textview lbl = (textview)view.findviewbyid(r.id.label);         textview prop = (textview)view.findviewbyid(r.id.prop);         lbl.settext(item.getlabel());          prop.settext(item.getprop());          return view;      }   } 

1. use viewholder pattern smooth list scrolling
2. implement offscreen page limit initialising view before showing inside viewpager
