想通过frame的button跳转到javafx的listview，发现第一次关闭javafx窗口后再次打开就会报错，因为它提示Application launch must not be called more than once，问题是我窗口已经关闭了，不能被调用两次怎么解决呢？
frame上的button监听代码如下：
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
new Thread(new Runnable() {
//
@Override
public void run() {
// TODO Auto-generated method stub
ListViewSample listViewSample=new ListViewSample();
listViewSample.main(null);
//listViewSample.start(null);
}
}).start();
// listViewSample.main();
}
});
javafx代码如下
public class ListViewSample extends Application {
// public static final ObservableList data
// = FXCollections.observableArrayList();
public ObservableList<String> strList=FXCollections.observableArrayList("红色","黄色","绿色");
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
//Platform.setImplicitExit(true);
primaryStage.setTitle("List View Sample");
ListView<String> listView2=new ListView<>();
listView2.setItems(strList);
listView2.setPrefSize(400, 200);
StackPane root = new StackPane();
root.getChildren().add(listView2);
primaryStage.setScene(new Scene(root, 400, 200));
primaryStage.show();
primaryStage.setOnCloseRequest(new EventHandler<WindowEvent>() {
@Override
public void handle(WindowEvent event) {
System.out.print("监听到窗口关闭");
}
});
listView2.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<Object>() {
@Override
public void changed(ObservableValue<? extends Object> observable, Object oldValue, Object newValue) {
// TODO Auto-generated method stub
EsitFrame esitFrame=new EsitFrame();
esitFrame.setVisible(true);
System.out.println(newValue);
// frame.add(label);
}
});
}
主要是想实现点击button传输指令到单片机，单片机返回的数据利用listview显示返回的数据，然后点击每个item再触发其他事件
