as understand want load yours html file assets webview clicking items in drawermenu? if it's you need add lines onclicklistener of yours listview in drawer:
mdrawerlist.setonitemclicklistener(new adapterview.onitemclicklistener() { @override public void onitemclick(adapterview<?> parent, view view, int position, long id) { toast.maketext(mainactivity.this, "time upgrade!", toast.length_short).show(); //load file webview mwebview.loadurl("replace_it_with_path_to_file"); //close drawer mdrawerlayout.closedrawers(); } });
