parent list adapter :

where parent list loads

child adapter:

public view getview(int position, view convertview, viewgroup parent) {      viewholder holder;     string item = null, qty = null;     if (convertview == null) {         holder = new viewholder();         convertview = inflator.inflate(r.layout.itembumpingadapter, null);         holder.qty = (textview) convertview.findviewbyid(r.id.qty);         holder.name = (textview) convertview.findviewbyid(r.id.item);         holder.childtext = (textview) convertview                 .findviewbyid(r.id.childitem);         holder.qtychild = (textview) convertview                 .findviewbyid(r.id.qtychild);         holder.checkbox = (checkbox) convertview.findviewbyid(r.id.chckbox1);         convertview.settag(holder);       } else {          holder = (viewholder) convertview.gettag();     }     parentobjid = newlistitems.get(position).getparentobjectid();     if (!parentobjid.isempty()) {         holder.name.settext("   " + newlistitems.get(position).getitemnnamedisplay());         holder.name.settextcolor(color.parsecolor("#cc0000"));         holder.qty.settext("      " + string.valueof(newlistitems.get(position)                 .getquantitydisplay()));         holder.qty.settextcolor(color.parsecolor("#cc0000"));     } else {          holder.name.settext(newlistitems.get(position).getitemnnamedisplay());         holder.qty.settext(string.valueof(newlistitems.get(position)                 .getquantitydisplay()));         holder.name.settextcolor(color.parsecolor("#ffffff"));         holder.qty.settextcolor(color.parsecolor("#ffffff"));         holder.checkbox.setchecked(false);          holder.checkbox.settag(position);          holder.checkbox.setonclicklistener(new onclicklistener() {               @override             public void onclick(view v) {                  int pos = (integer) v.gettag();                 newlistitems.get(pos).setchecked(!newlistitems.get(pos).ischecked());              }          });         if (newlistitems.get(position).ischecked()) {             holder.name.setenabled(true);             holder.name.setbackgroundcolor(color.parsecolor("#dcdbdb"));           } else {             holder.name.setenabled(false);         }       }     return convertview; }

you should use expandablelistview if have child list parent list. if not familiar check this link learn more.

there onchildclicklistener provided expandablelistview when clicked gives both, child's position , parents's position:

// listview on child click listener explistview.setonchildclicklistener(new onchildclicklistener() {          @override         public boolean onchildclick(expandablelistview parent, view v,                 int groupposition, int childposition, long id) {             // todo auto-generated method stub             toast.maketext(                     getapplicationcontext(),                     listdataheader.get(groupposition)                             + " : "                             + listdatachild.get(                                     listdataheader.get(groupposition)).get(                                     childposition), toast.length_short)                     .show();             return false;         }     });

hope helps!!
