android - How to get the id of a particular switch in a custom list view and check it -


this getview() code. want access particular switch in custom listview. doing wrong ?

public view getview(final int position, view convertview, viewgroup parent) {               if(convertview==null)             {                 //inflate custom layout                 convertview = inflater.from(parent.getcontext()).inflate(r.layout.list_item,parent,false);                 viewholder=new viewholder();                  //cache views                 viewholder.sw=(switch) convertview.findviewbyid(r.id.switch1);                 viewholder.name=(textview) convertview.findviewbyid(r.id.name);                 viewholder.rollno=(textview) convertview.findviewbyid(r.id.roll);                  viewholder.id=(textview) convertview.findviewbyid(r.id.id);                  //link cached views convertview                 convertview.settag(viewholder);              }             else                 viewholder=(viewholder) convertview.gettag();                //set data displayed              viewholder.name.settext(studentlist.get(position).get("name").tostring());             viewholder.rollno.settext(studentlist.get(position).get("roll_no").tostring());             viewholder.id.settext(studentlist.get(position).get("id").tostring());             viewholder.sw.settext("");              (int s : absentmarked) {                  log.d("marked",integer.tostring(s));                  if(s==1){                      log.d("entered","yes");                      viewholder.sw=(switch) convertview.findviewbyid(r.id.switch1);                     viewholder.sw.setchecked(true);                 }              }

this problem exist. checks switches true. want access particular switch in list view , check it. absentmarked array list contains 0 , 1. want check switch true corresponding 1 value

for (int s : absentmarked) {                  log.d("marked",integer.tostring(s));                  if(s==1){                      log.d("entered","yes");                      viewholder.sw=(switch) convertview.findviewbyid(r.id.switch1);                     viewholder.sw.setchecked(true);                 }              }

you should add field absentmarked in model.

   if(studentlist.get(position).get("absentmarked")==1){     log.d("entered","yes");    viewholder.sw.setchecked(true);     }else{ viewholder.sw.setchecked(false); }

and add setoncheckedchangelistner switch toggle value of absentmarked follows:

    sw.setoncheckedchangelistener(new compoundbutton.oncheckedchangelistener() {         @override         public void oncheckedchanged(compoundbutton compoundbutton, boolean b) {             if(b){               setabsentmarked(1);             } else{               setabsentmarked(0);         }     });
