javafx实现并显示ListView [英] javafx implementing and showing a ListView

问题描述

我想要一个带有"Persons"名称的ListView，但是当我启动该应用程序时，在ListView上，我看到了一些奇怪的字符串而不是(字符串)名称.我认为这是人"对象的强制问题.我不知道ListView应该是ListView还是ListView.因为当我尝试在listview上设置项目时，使用setItems(ObservableList)可以得到显示在列表上的怪异字符串..这是代码:

I want to have a ListView with the name of the "Persons", but on the ListView when I launch the application, I see some weird strings instead of the (string)names. I think it is a cast problem of the "Person"-object. I didnt know if the ListView should be ListView or ListView. Because when I try to set the items on the listview, using setItems(ObservableList) i get that weird Strings on list shown.. here is the code:

MainApp.java:

MainApp.java:

 public static ObservableList<Person> personList;

 public static void main(String[] args) {
    personList = FXCollections.observableArrayList();
    Person p1 = new Person("Tom");
    Person p2 = new Person("Anna");

    personList.add(p1);
    personList.add(p2);
    launch(args);
}

PersonController.java:

PersonController.java:

import static ordercheck.OrderCheck.personList;

public class PersonalController implements Initializable {
@FXML
private ListView<Person> personalList;
 public void initialize(URL url, ResourceBundle rb) {
   personalList.setItems(personList);
....
....
}

....
....
}

我怎么能看到真实姓名而不是这样的字符串:ordercheck.model.Person@2c5ds8dsf8sdf8

how could I see the real names and not such strings: ordercheck.model.Person@2c5ds8dsf8sdf8

谢谢！

推荐答案

任一:

a.覆盖 toString 方法您的Person类.

a. Override the toString method in your Person class.

或

b.设置 cellFactory 在ListView上，然后在此处设置格式文本.

b. Set a cellFactory on the ListView and set your formatted text there.

(a)最简单. .
