u can make without using expandable list-view..u have control visibility of views.
mainactivity
boolean flag; boolean flag2; linearlayout llcontains; linearlayout llcontents; linearlayout llcontains2; linearlayout llcontents2; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); llcontains = (linearlayout)findviewbyid(r.id.llcontains); llcontents = (linearlayout)findviewbyid(r.id.llcontents); llcontains2 = (linearlayout)findviewbyid(r.id.llcontains2); llcontents2 = (linearlayout)findviewbyid(r.id.llcontents2); llcontains.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { if(!flag) { llcontents.setvisibility(view.visible); flag = true; } else { llcontents.setvisibility(view.gone); flag = false; } } }); llcontains2.setonclicklistener(new onclicklistener() { @override public void onclick(view v) { if(!flag2) { llcontents2.setvisibility(view.visible); flag2 = true; } else { llcontents2.setvisibility(view.gone); flag2 = false; } } }); } activity_main.xml
