我有一个JavaFX Application和ListView。我想基于不是控制器的另一个类的事件来更新此ListView(此类与JavaFX无关)。如果我调用自己的书面方法,它将执行诸如System.out.println(“ Debug”)之类的常规代码,但不会执行AnListView.getItems().add("Pork");
所以我的问题是如何使它还执行列表中项目的更新!
在ButtonClickEvent中进行更新时,它工作得很好。
package gui.controller;
import java.net.URL;
import java.util.ArrayList;
import java.util.ResourceBundle;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.control.ListView;
import main.Main;
import utils.Player;
public class ListViewController implements Initializable
{
@FXML
private ListView<String> AllPlayersList;
private ListView<String> TeamBlueList;
private ListView<String> TeamRedList;
private Button Button;
@Override
public void initialize(URL location, ResourceBundle resources) {
}
public void update() {
AllPlayersList.getItems().add("Pork");
System.out.println("FUCK");
}
@FXML
private void handleButtonAction(ActionEvent event) {
update();
}
}
我用来调用更新函数的代码:
FXMLLoader fxmlLoader = new FXMLLoader();
try {
Pane p = fxmlLoader.load(getClass().getResource("../gui/MainWindowFX.fxml").openStream());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
ListViewController fooController = (ListViewController) fxmlLoader.getController();
fooController.update();
我使用并打开了FXML文件:

<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.layout.AnchorPane?>

我想使用update()函数更新列表。
