次のようなカスタムアダプターがあります。私の目的は、今後の予定と過去の予定を 1 つに表示することですListView。だから私は一緒に行くことにしましCustom ArrayAdapterた。しかし、 getView() が呼び出されない理由がわかりません。また、オーバーライドgetCount()すると、サイズとして 50 が得られますitems
public class AppointmentListAdapter extends ArrayAdapter<Item> {
List<Item> items;
private Context context;
private LayoutInflater vi;
public static boolean pastApptSectionDrawn = false;
private int healowUserId, portalUserId;
public AppointmentListAdapter(Context context, List<Item> items, int healowUserId, int portalUserId){
super(context, 0, items);
this.context = context;
this.items = items;
vi = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.healowUserId = healowUserId;
this.portalUserId = portalUserId;
