我在listview角色上有项目,但是在window中运行后它们没有显示在我的程序中。 Gui在Scene Builder中完成。当我运行程序字段时,项目应该是白色空白,只是空白。
程序的打印屏幕 https://zapodaj.net/c60f99a10f300.jpg.html
场景构建器 https://zapodaj.net/26fbf2123397c.jpg.html
当我在Scene Builder中使用显示示例数据时,它会显示lorem ipsum等。
在这里,您从控制器和fmxl文档中获取了代码。
if(currentUser.collegeLevel === "Associates Degree" || currentUser.collegeLevel === "High School")
fxml
package sample;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.Button;
import javafx.scene.control.ListView;
import javafx.scene.control.SelectionMode;
import java.net.URL;
import java.util.*;
public class ControllerBindColors implements Initializable {
@FXML
private ListView<String > roles;
@FXML
private ListView<String> colors;
@FXML
private ListView<?> binded;
String selectedRole;
String selectedColor;
int numberOfPlayers;
@Override
public void initialize(URL location, ResourceBundle resources) {
}
public void initData(int numberOfPlayers, String selectedRole, String selectedColor) {
this.numberOfPlayers = numberOfPlayers;
this.selectedRole = selectedRole;
this.selectedColor = selectedColor;
ObservableList<String> itemsRoles = FXCollections.observableArrayList("test","test2","test3");
roles = new ListView<>();
roles.setItems(itemsRoles);
roles.getItems().addAll("test555");
roles.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
System.out.println(roles.getItems());
}
}
initData 激活按钮时调用ControllerNewGame.java startGame()

列表中有确定的项目,在控制台中,所有4个项目均已打印 [test,test2,test3,test555]
答案 0 :(得分:0)
要获得对FXML
使用的控制器的引用(而不是构造一个新的控制器):
FXMLLoader loader = new FXMLLoader();
Parent root= loader.load(getClass().getResource("BindColor.fxml").openStream());
ControllerBindColors controller = fxmlLoader.getController();
获得对它的引用后,可以像以前一样使用它:
controller.initData(number,selectedRole.getText(),selectedColor.getText());
