[Android] - Problème rafraichissement Listview

Bonjour,

Voila j'ai un problème pour rafraîchir les données d'une Listview . Je fais pourtant les changements comme il se doit au niveau de l'ArrayAdapter en nettoyant et en ajoutant les objets de ma nouvelle liste à la liste courante de l'Adpater. Je ne vois vraiment pas où est l'erreur. D'avance merci pour votre aide.

public class SearchImageActivity extends AbstractNavDrawerActivity {
 
    private ExportMenuRecherche mExportMenuRecherche;
    private ExportMenuCarthoteque mExportMenuCarthoteque;
 
    private String mQuery;
 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        handleIntent(getIntent());
    }
 
    @Override
    protected NavDrawerActivityConfiguration getNavDrawerConfiguration() {
 
 
 
        mExportMenuRecherche = ExportMenuRecherche.getInstance(this);
        mExportMenuCarthoteque = ExportMenuCarthoteque.getInstance(this);
 
        ArrayList<NavDrawerItem> menu = mExportMenuCarthoteque.exportMenu(getCarthoteque());
 
        NavDrawerActivityConfiguration navDrawerActivityConfiguration = new NavDrawerActivityConfiguration();
        navDrawerActivityConfiguration.setMainLayout(R.layout.activity_main);
        navDrawerActivityConfiguration.setDrawerLayoutId(R.id.drawer_layout);
        navDrawerActivityConfiguration.setLeftDrawerId(R.id.left_drawer);
        navDrawerActivityConfiguration.setNavItems(menu);
        navDrawerActivityConfiguration.setDrawerShadow(R.drawable.drawer_shadow);     
        navDrawerActivityConfiguration.setDrawerOpenDesc(R.string.drawer_open);
        navDrawerActivityConfiguration.setDrawerCloseDesc(R.string.drawer_close);
        navDrawerActivityConfiguration.setBaseAdapter(
            new NavDrawerAdapter(this, R.layout.navdrawer_item, menu ));
        return navDrawerActivityConfiguration;
    }
 
 
 
    @Override
    protected void onNewIntent(Intent intent) { 
        handleIntent(intent);
    }
 
    private void handleIntent(Intent intent) {
 
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
            String query = intent.getStringExtra(SearchManager.QUERY);
 
            ArrayList<NavDrawerItem> menu = mExportMenuRecherche.exportMenu(getCarthoteque(), mQuery);
 
            NavDrawerActivityConfiguration navDrawerActivityConfiguration = getNavConf();
            navDrawerActivityConfiguration.setNavItems(menu);
            NavDrawerAdapter navDrawerAdapter = (NavDrawerAdapter) navDrawerActivityConfiguration.getBaseAdapter();
            navDrawerAdapter.setDataSource(menu);
        }
    }
}

Je précise que la méthode getNavDrawerConfiguration() est appelée dans les OnCreate() de la classe mère. C'est la qu'est instancié l'ArrayAdapter avec une première liste. Puis je souhaite la mettre à jour avec une nouvelle liste par la suite dans la méthode handleIntent.
