java - ListView Viewholder checkbox state -

i've problems listview custom adapter (and newly implemented viewholder). have listview checkbox each item (nothing new here). problem is, if there more 9 items in list, when check first checkbox, tenth automatically checked (same second eleventh) if there 1 listener both item (and beleive it's case in way).

i read position issue listview, view recycling , viewholder way solve here: how can make arrayadapter follow viewholder pattern?

but made wrong because it's not working...

public class presencelistadapter extends simpleadapter { private layoutinflater  inflater; private list<integer> ids; private list<string> statuts;  public presencelistadapter (context context, list<? extends map<string, ?>> data, int resource, string[] from, int[] to, list<integer> ids, list<string> statuts) {     super (context, data, resource, from, to);     inflater = layoutinflater.from (context);     this.ids = ids;     this.statuts= statuts;  }  @override public object getitem (int position) {     return super.getitem (position); }  @override public view getview (int position, view convertview, viewgroup parent) {      viewholder holder;      if (convertview == null)     {         convertview = inflater.inflate (r.layout.list_text_checkbox, null);          holder = new viewholder();          holder.btn = (button) convertview.findviewbyid(r.id.btnretard);         holder.check = (checkbox) convertview.findviewbyid(r.id.checkpresent);          if (statuts.get(position).equals("p")) {             drawable img = inflater.getcontext().getresources().getdrawable(android.r.drawable.presence_online);             holder.btn.setcompounddrawableswithintrinsicbounds( img, null, null, null );             holder.btn.setenabled(true);             holder.check.setchecked(true);         }         else if(statuts.get(position).equals("r"))         {             drawable img = inflater.getcontext().getresources().getdrawable(android.r.drawable.presence_away);             holder.btn.setcompounddrawableswithintrinsicbounds( img, null, null, null );             holder.btn.setenabled(true);             holder.check.setchecked(true);         }         else          {             drawable img = inflater.getcontext().getresources().getdrawable(android.r.drawable.presence_invisible);             holder.btn.setcompounddrawableswithintrinsicbounds( img, null, null, null );             holder.check.setchecked(false);         }          convertview.settag(holder);     }     else      {         holder = (viewholder) convertview.gettag();     }      int id = ids.get(position);      if(id != 0)     {         holder.check.settag(id);         holder.btn.settag(id);     }      return super.getview (position, convertview, parent); }  static class viewholder {     button btn;     checkbox check; } 

and listener: public void changerpresent(view v) {

    checkbox checkpresent = (checkbox) v;     int idpersonne = (integer) checkpresent.gettag();     view parent = (view)v.getparent();     button btn = (button) parent.findviewbyid(r.id.btnretard);      if(checkpresent.ischecked()) {         gestion.updatepresence(idpersonne, idseance, "p");          btn.setenabled(true);         setbtnretardpresent(btn);                }     else      {         gestion.updatepresence(idpersonne, idseance, "a");         btn.setenabled(false);         setbtnretardabsent(btn);      }  } 

i appreciate @ point, i'm working on hours now.

thank much.

here's how made work:

first, need separate array checked state. has same size adapter's getcount().

then on getview, checkbox's setoncheckedchangedlistener must preceed checkbox.setchecked statements.

example:

holder.checkbox.setoncheckedchangelistener(new oncheckedchangelistener() {   @override   public void oncheckedchanged(compoundbutton buttonview, boolean ischecked) {     ischecked[position] = ischecked;   } });  holder.checkbox.setchecked(ischecked[position]);
