JavaFX-ListView组件

使用idea创建一个javafx项目

 修改FXML布局文件

编写HelloApplication类

import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.ListView;
import javafx.scene.control.SelectionMode;
import javafx.stage.Stage;

import java.io.IOException;

public class HelloApplication extends Application {

    private ListView listView;

    public void showListView() {
        ObservableList list = FXCollections.observableArrayList();
        list.add("张三");
        list.add("张三1");
        list.add("张三3");
        list.add("李四1");
        list.add("李四2");
        list.add("张三6");
        list.add("李四3");
        listView.setItems(list);
        listView.getSelectionModel().setSelectionMode(SelectionMode.SINGLE);
    }

    @Override
    public void start(Stage stage) throws IOException {
//        Parent root = FXMLLoader.load(getClass().getResource("hello-view.fxml"));
//        Scene scene = new Scene(root);
        //初始化FXML布局文件内容
        FXMLLoader fxmlLoader = new FXMLLoader(HelloApplication.class.getResource("hello-view.fxml"));
        //父级
        Parent root = fxmlLoader.load();
        //根据fx:id从父级root布局中查询并实例化listView组件
        listView= (ListView) root.lookup("#listView");
        //渲染listView组件
        showListView();
        //设置标题
        stage.setTitle("JavaFx示例");
        //实例化场景长宽
        Scene scene = new Scene(root, 400, 240);
        //设置场景
        stage.setScene(scene);
        //渲染场景
        stage.show();
    }

    public static void main(String[] args) {
        launch();
    }

}
