my app working until click 1 of child element in expandablelist view.and don't know why because looking fine.here main activity:
explistview = (expandablelistview) findviewbyid(r.id.lvexp); explistview2 = (expandablelistview) findviewbyid(r.id.lvexp2); explistview3 = (expandablelistview) findviewbyid(r.id.lvexp3); explistview4 = (expandablelistview) findviewbyid(r.id.lvexp4);

and here adapter:

so can problem? appreciated.
