当用户点击从数据库中检索到的特定约会时,我想打印预约summarydescription

我试图通过以下方式实现此目的:

lAgenda.selectedAppointments().addListener(new ListChangeListener<Appointment>() {
            @Override
            public void onChanged(Change<? extends Appointment> c) {
                System.out.println(c.toString());
            }
        });
然而,我只能得到这个:

com.sun.javafx.collections.NonIterableChange$GenericAddRemoveChange@1ef0f08
com.sun.javafx.collections.NonIterableChange$SimpleAddChange@1c3e48b
com.sun.javafx.collections.NonIterableChange$GenericAddRemoveChange@d57e70
com.sun.javafx.collections.NonIterableChange$SimpleAddChange@6022e2
com.sun.javafx.collections.NonIterableChange$GenericAddRemoveChange@54ddc1

如何检索其他项目,例如从中检索约会的数据库行中的行ID?谢谢大家。

您正在使用正确的属性来通知选择更改。

您收到了ListChangeListener.Change。如javadoc中所述,应该以这种方式使用更改:

 lAgenda.selectedAppointments().addListener(new ListChangeListener< Appointment >() {
     public void onChanged(Change<? extends Appointment> c) {
         while (c.next()) {
             if (c.wasPermutated()) {
                 for (int i = c.getFrom(); i < c.getTo(); ++i) {
                      //permutate
                 }
             } else if (c.wasUpdated()) {
                      //update item
             } else {
                 for (Appointment a : c.getRemoved()) {
                 }
                 for (Appointment a : c.getAddedSubList()) {
                     printAppointment(a);
                 }
             }
         }
     }
 });

现在,您可以打印出appointment摘要和说明:

private void printAppointment(Appointment a) {
    System.out(a.getSummary());
    System.out(a.getDescription());
}

如果您需要约会对象的某些特定属性(如数据库ID),您可以通过扩展AppointmentImpl或实施Appointment来创建约会类
