java - All textView are modify in Custom ListAdapter after AlertDialog -

i fill arraylist <'hashmap <'string, string>> asynctask , set adapter custom adapter , , creat each view in getview() . until here , works. pet listener on linear_layout open alertdialog edittextfield. , when want change textview after have clicked , textview change , when scrool , come , start value (that in asynctask) appear. it's if value not save @ position.

this getview() method :

@override public view getview(int position, view convertview, viewgroup parent) {        if (convertview == null) {       holder = new customlistingcrossholder();          convertview = m_inflater.inflate(r.layout.list_type_tournee, null);               holder.miscellaneous = (textview) convertview.findviewbyid(r.id.miscellaneous);       holder.infos = (textview) convertview.findviewbyid(r.id.infos);        holder.linear_divers = (linearlayout) convertview.findviewbyid(r.id.test);        convertview.settag(holder);       } else {       holder = (customlistingcrossholder) convertview.gettag();      }              holder.miscellaneous.settext(this.listitem.get(position).get("miscellaneous"));       holder.infos.settext(this.listitem.get(position).get("infos"));        holder.linear_divers.setonclicklistener(new view.onclicklistener()          {            view alertdialogview = m_inflater.inflate(r.layout.alert_dialog_divers, null);             public void onclick(view v)              {                    customlistingcrossholder cmh = (customlistingcrossholder) v.gettag();                  alertdialog.builder adb = new alertdialog.builder(ctx);                       final edittext input = new edittext(ctx);                 adb.setview(input);                 adb.setpositivebutton("ok", new dialoginterface.onclicklistener()                 {                     @override                     public void onclick(dialoginterface dialog, int whichbutton)                     {                                                 diver_edit = input.gettext().tostring();                       holder.miscellaneous.settext(diver_edit);             // it's here change textview                      }                 });                 adb.setnegativebutton("cancel", null);                 adb.create().show();              }          });              return convertview;     }  

and holder class :

    private class customlistingcrossholder {      textview infos;     textview miscellaneous;     linearlayout linear_divers;  } 

so can't "save" value of textfield of alertdialog position , don't change when scroll.may know correct way achieve objective?

edit 1 : call listview in onpostexecute of asynctask code set adapter :

@override protected void onpostexecute(string result) {     super.onpostexecute(result);     this.pdialog.dismiss();      log.i("asynctasklistcrossingpoint", "onpostexecute");      jsonarray jarray = new jsonarray();     jsonobject json_data = null;     hashmap<string, string> map;     arraylist<hashmap<string, string>> listitem = new arraylist<hashmap<string, string>>();      if (!result.startswith("error", 2)) {         // recuperation des donnees json         try {             jarray = new jsonarray(result);         } catch (jsonexception e) {             log.i("tagjsonexp", "" + e.tostring());         } catch (parseexception e) {             log.i("tagjsonpars", "" + e.tostring());         }         log.i("jarray", jarray.tostring());          // insertion des données json dans un hashmap         (int = 0; < jarray.length(); i++) {             try {                  json_data = jarray.getjsonobject(i);                  map = new hashmap<string, string>();                  map.put("miscellaneous",json_data.getstring("miscellaneous") != "null" ? json_data.getstring("miscellaneous") : "aucune");                 map.put("infos",json_data.getstring("infos") != "null" ? json_data.getstring("infos") : "aucune");                 listitem.add(map);              } catch (jsonexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             }         }          this.adapter = new customlistingcrossadapter(this.mycontext, listitem);         listview.setadapter(this.adapter);      } } 

and code @ top of post getview method in customlistingcrossadapter

i resolved problem. put

final hashmap<string, string> object = (hashmap<string, string>) this.getitem(position); 

to item @ position of click , put new value same name key in hashmap :

 holder.linear_divers.setonclicklistener(new view.onclicklistener()          {              public void onclick(view v)              {                                     alertdialog.builder adb = new alertdialog.builder(ctx);                       final edittext input = new edittext(ctx);                 adb.setview(input);                 adb.setpositivebutton("ok", new dialoginterface.onclicklistener()                 {                     @override                     public void onclick(dialoginterface dialog, int whichbutton)                     {                                                 diver_edit = input.gettext().tostring();                                                   object.put("miscellaneous", diver_edit);                       //^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^                       log.i("objet", "o : " + object.get("miscellaneous"));                      }                 });                 adb.setnegativebutton("cancel", null);                 adb.create().show();                                 }                        });
