what want:

add:

public class servicesadapter extends baseexpandablelistadapter {      private static final string tag = servicesadapter.class.getsimplename();     private arraylist<hashmap<string, string>> group;     arraylist<arraylist<hashmap<string, string>>> child;     private context context;      private static string group_name = "group_name";     private static string group_image = "group_image";     private static string child_name = "child_name";      public servicesadapter(context context, arraylist<hashmap<string, string>> group, arraylist<arraylist<hashmap<string, string>>> child) {         this.context = context;         this.group = group;         this.child = child;     }      @override     public int getgroupcount() {         return group.size();     }      @override     public int getchildrencount(int groupposition) {         return child.get(groupposition).size();     }      @override     public object getgroup(int groupposition) {         return group.get(groupposition);     }      @override     public object getchild(int groupposition, int childposition) {         return child.get(groupposition).get(childposition);     }      @override     public long getgroupid(int groupposition) {         return groupposition;     }      @override     public long getchildid(int groupposition, int childposition) {         return childposition;     }      @override     public boolean hasstableids() {         return true;     }      @override     public view getgroupview(int groupposition, boolean isexpanded, view convertview, viewgroup parent) {         if (convertview == null) {             layoutinflater infalinflater = (layoutinflater) context                     .getsystemservice(context.layout_inflater_service);             convertview = infalinflater.inflate(r.layout.list_fragment_services_groups, null);         }          if (isexpanded) {             convertview.setbackgroundresource(r.drawable.expandblelistview_background_selected);         } else {             convertview.setbackgroundresource(r.drawable.expandblelistview_background);         }          imageview imgservicesgroup = (imageview) convertview.findviewbyid(r.id.imgservicesgroup);         textview txtservicesgroup = (textview) convertview.findviewbyid(r.id.txtservicesgroup);          txtservicesgroup.settext(group.get(groupposition).get(group_name));         int imageid = context.getresources().getidentifier("ic_" + group.get(groupposition).get(group_image), "drawable", context.getpackagename());         imgservicesgroup.setimageresource(imageid);          return convertview;     }      @override     public view getchildview(int groupposition, int childposition, boolean islastchild, view convertview, viewgroup parent) {          if (convertview == null) {             layoutinflater infalinflater = (layoutinflater) context                     .getsystemservice(context.layout_inflater_service);             convertview = infalinflater.inflate(                     r.layout.list_fragment_services_child, null);         }          textview txtserviceschild = (textview) convertview.findviewbyid(r.id.txtserviceschild);         txtserviceschild.settext(child.get(groupposition).get(childposition).get(child_name));          return convertview;     }      @override     public boolean ischildselectable(int groupposition, int childposition) {         return false;     } } 

i think can set background expandablelistview
