i not think updating list when edit text changes. need notify adapter data has changed. adaptercatarticulos.notifydatasetchanged();
final listview listaarticulos=(listview)findviewbyid(r.id.lvarticulos); adaptercatarticulos=new listviewadapter_catarticulos(this,nomarticulo,unidad,precio,idarticulo); listaarticulos.setadapter(adaptercatarticulos); listaarticulos.setonitemclicklistener(new adapterview.onitemclicklistener() { @override public void onitemclick(adapterview<?> adapterview, view view, int i, long l) { final textview txt =(textview) view.findviewbyid(r.id.txtarticulo); tostadora(txt.gettext().tostring()); } }); adaptercatarticulos.notifydatasetchanged(); }else { if (txtfiltro.gettext().tostring().equals("")){ tostadora("no hay registros para presentar"); }else { tostadora("la busqueda no permite filtar mas registros"); } }
