-

here using activity in there list view,which populating form xml string,the population fine,in listview there 2 buttons

clicking on no increasing , decreasing.onsubmit buttons want datum modified 1 shown in submit.e.g 2 seaters selected 2.

the code snippts are:

my xml  private static string seatxml="<?xml version=\"1.0\" encoding=\"utf-8\"?><seatlist>"         +"<seatselection><seater>two</seater></seatselection>"         +"<seatselection><seater>four</seater></seatselection>"         +"<seatselection><seater>six</seater></seatselection>"         +"<seatselection><seater>eight</seater></seatselection>"         +"<seatselection><seater>ten</seater></seatselection>"         +"</seatlist>";

here populating listview

private void populateseatlist() {     // todo auto-generated method stub     seatitems=new arraylist<hashmap<string,string>>();     xmlparser parser=new xmlparser();     document doc=parser.getdomelement(seatxml);     nodelist nl=doc.getelementsbytagname(key_record);     string seatname="";      (int = 0; < nl.getlength(); i++) {         map=new hashmap<string, string>();         element e=(element)nl.item(i);         // adding each child node hashmap key => value         map.put(key_seat,parser.getvalue(e, key_seat)); //this fetch seater value 2 seater,3 seater         map.put(key_seat_qty,""+qty);         seatitems.add(map);     }      adapter=new seatadapter(this, seatitems);     seatlistview.setadapter(adapter);     //      makeatoast(seatname);  }

the getview function in adapter class

int i=0; @override public view getview(final int position, view convertview, viewgroup parent) {     // todo auto-generated method stub     view view=convertview;     if(convertview==null)         view=inflater.inflate(r.layout.seat_desc,null);     textview seatname=(textview)view.findviewbyid(r.id.textview_seat_no);     button buttonminus=(button)view.findviewbyid(r.id.button_minus);     button buttonplus=(button)view.findviewbyid(r.id.button_plus);     final textview seatinput=(textview)view.findviewbyid(r.id.textview_seat_input);      seatinfo=new hashmap<string, string>();     seatinfo=data.get(position);      seatname.settext(seatinfo.get(seatselectionactivity.key_seat)+" seater:");     seatinput.settext(""+i);      //    menuinfo.get(menuscreenactivity.key_menuname)     buttonplus.setonclicklistener(new onclicklistener() {          @override         public void onclick(view v) {             // todo auto-generated stub             i=integer.parseint(seatinput.gettext().tostring());             if(!(i>=10))                 i++;             seatinput.settext(""+i);             //              seatinfo.put(seatselectionactivity.key_seat, seatinfo.get(seatselectionactivity.key_seat));             seatinfo.put(seatselectionactivity.key_seat_qty,seatinput.gettext().tostring());             data.set(position, seatinfo);             //              notifydatasetchanged();          }     });      buttonminus.setonclicklistener(new onclicklistener() {          @override         public void onclick(view v) {             // todo ,goto-generated method stub             i=integer.parseint(seatinput.gettext().tostring());             if(!(i<1))                 i--;             seatinput.settext(""+i);             //              seatinfo.put(seatselectionactivity.key_seat, seatinfo.get(seatselectionactivity.key_seat));             seatinfo.put(seatselectionactivity.key_seat_qty,seatinput.gettext().tostring());             data.set(position, seatinfo);             //              notifydatasetchanged();         }     });      return view; }

if needed sample project

i used code selected seats & worked

buttonplus.setonclicklistener(new onclicklistener() {          @override         public void onclick(view v) {             // todo auto-generated stub             i=integer.parseint(seatinput.gettext().tostring());             if(!(i>=10))                 i++;             seatinput.settext(""+i);              data.get(position).put(seatselectionactivity.key_seat_qty, seatinput.gettext().tostring());          }     });
