ListView statique et dynamique
j'ai une listview dynamique (jai utilisé XML parser pour parser les données à partir de web service )
et maintenant je veux ajouter 4 item à cette liste view dynamique
ArrayList<String> maListe_principale = new ArrayList<String>();
maListe_principale.add(" Accueil" );
maListe_principale.add(" item1" );
maListe_principale.add(" item2" );
maListe_principale.add(" item3" );
maListe_principale.add(" item4" );
voila mon code :
la premiere classe contient les getters et setters
