public class interactivearrayadapter extends arrayadapter<student> implements filterable { final string namespace = "http://ws.sams.com"; string url = "http://88.198.82.92:8080/sams1/services/insertdataws?wsdl"; // usint // localhost final string method_name = "insertapsentdata"; final string soap_action = "http://ws.sams.com/insertapsentdata"; list<integer> checkboxstate = new arraylist<integer>(200); // list<integer> checkboxstate2 = new arraylist<integer>(200); // list<integer> checkboxstate3 = new arraylist<integer>(200); // set<integer> numbers = new hashset<integer>(); private final list<student> studentnameslist; // student names . private final list<student> studentidslist;

protected checkbox checkbox; protected checkbox checkbox2; protected checkbox checkbox3; protected tablerow row; } public view getview(final int position, view convertview, viewgroup parent) { view view = null; if (convertview == null) { layoutinflater inflator = context.getlayoutinflater(); view = inflator.inflate(r.layout.rep, null); viewholder viewholder = new viewholder(); viewholder.studentname = (textview) view .findviewbyid(r.id.textview07);

androidhttptransport.call(soap_action, envelope); } catch (exception e) { } } } }); return view; } }
if know items checked or unchecked before starting set adapter using this
if (checkboxstate.contains(categories.get(position).categoryid)) { holder.checkbox.setchecked(true); } else { holder.checkbox.setchecked(false); } then continue code this
holder.checkbox .setoncheckedchangelistener(new oncheckedchangelistener() { public void oncheckedchanged(compoundbutton buttonview, boolean ischecked) { if (ischecked) { checkboxstate.add(categories.get(position).categoryid); } else { checkboxstate.remove(categories.get(position).categoryid); } } });
