android - expandablelistview with multiple textviews -


i have expandablelistview, parent has 4 textviews , children, 4 textviews also.

i know how can populate if have 1 element on parent , 1 on child, 4 don't.

i think must have data in separate arraylists.

  numerosservicios = new arraylist<string>();     profesiones = new arraylist<string>();     direcciones = new arraylist<string>();     fechascaduca = new arraylist<string>();     tipos = new arraylist<string>();     diasencurso = new arraylist<string>();     fechasproximascitas = new arraylist<string>();     estados = new arraylist<string>();

but don't know how should make adapter. see code don't understand it.

anyone has example please? thanks

edit

i found "solution":

    private list<? extends list<? extends map<string, ?>>> crealistadehijos() {                     arraylist resultado_hijo = new arraylist();                     for(int i=0;i<=arrayservicios.size();i++){                         hashmap hijo = new hashmap();                         hijo.put("tipo", tipos.get(i));                         hijo.put("diasencurso", diasencurso.get(i));                         hijo.put("estado", estados.get(i));                         hijo.put("fechaprocita", fechasproximascitas.get(i));                         resultado_hijo.add(hijo);                     }                      return (list)resultado_hijo;    }                  private list<? extends map<string, ?>> crealistadegrupos() {                       arraylist resultado_padre = new arraylist();                     for(int i=0;i<=arrayservicios.size();i++){                         hashmap padre = new hashmap();                         padre.put("numero_servicio", numerosservicios.get(i));                         padre.put("profesion", profesiones.get(i));                         padre.put("direccion", direcciones.get(i));                         padre.put("fecha_cad", fechascaduca.get(i));                         resultado_padre.add(padre);                     }                      return (list)resultado_padre;                 } simpleexpandablelistadapter explistadapter = new simpleexpandablelistadapter(                         contexto,                         crealistadegrupos(),                         r.layout.linea_padre,                         new string[] { "numero_servicio","profesion","direccion","fecha_cad" },                         new int[] { r.id.tvservicio,r.id.tvprofesion,r.id.tvdireccion,r.id.tvdiasencurso},                               crealistadehijos(),                          r.layout.linea_hija,                             new string[] { "tipo", "diasencurso","estado","fechaprocita" },                          new int[] { r.id.tvtipo , r.id.tvdiasencurso, r.id.tvestado, r.id.tvfechaproximacita}                            );                  setlistadapter( explistadapter );                 registerforcontextmenu(getexpandablelistview());
