java - ListView displays different items than what is in the holder -

-

i have custom adapter extends baseadapter. has variety of different layouts thumbnails without. when add new item same type 1 before row displays same values. when check set in holder tells me correct items set.

public view getview(int position, view convertview, viewgroup parent) {     int layouttype = getitemviewtype(position);     listviewrow item = null;      if(convertview == null) {         item = atindex(position);         holder = new viewholder();         convertview = getconvertview(layouttype, parent);//viewholder items declared here         convertview.settag(-1, holder);     }     else if(!viewmatchestype(layouttype, convertview.getid())){         item = atindex(position);         holder = new viewholder();         convertview = getconvertview(layouttype, parent);//viewholder items declared here         convertview.settag(-1, holder);     }     else {         holder = (viewholder) convertview.gettag(-1);         item = atindex(position);     }      setdisplay(item, convertview);//i set values here      if(holder.tv_name.gettext() != item.getname()) {         notifydatasetinvalidated();     }      return convertview; }  //for performance, ui elements saved in holder private static class viewholder {     public imageview iv_thumbnail;     public textview tv_name; }

i havent found optimal solution problem myself, removing if condition seems work me. instead of this

if(convertview == null) {     item = atindex(position);     holder = new viewholder();     convertview = getconvertview(layouttype, parent);//viewholder items declared here     convertview.settag(-1, holder); }

just use this

    item = atindex(position);     holder = new viewholder();     convertview = getconvertview(layouttype, parent);//viewholder items declared here     convertview.settag(-1, holder);

it sure heavy on memory, haven't found other solution.
