java - How do I implement expandable List view setOnItemClickListener from button present in child view? -

-

i trying figure out how implement expandable list view setonitemclicklistener button present in child view. here's have far:

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.weekly_event_child_items, null);     }      button mybutton = (button) convertview.findviewbyid(r.id.button2);     mybutton.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v1) {             ((expandablelistview) parents).performitemclick(v1,positions, 0);         }     }); }

in main view have implemented:

expandablelistview.setonitemclicklistener(new adapterview.onitemclicklistener() {     @override     public void onitemclick(adapterview<?> adapterview, view view, int i, long l) {         system.out.println("clicked");     } });

i expecting ((expandablelistview) parents).performitemclick(v1,positions, 0 somehow make call event handler in expandablelistview.setonitemclicklistener, not happening. want make call button click present in child view make call expandable listview's item click listener.

i think method below:

public void onclick(view v1) {     ((expandablelistview) parents).performitemclick(v1,positions, 0); }

isn't implemented properly. if you're doing operation expandablelistview, can retrieve findviewbyid(...).

i think incorrect place set button event listener, since it's not related individual child views.
