在Javafx中，当文本区域获得焦点时，如何打开文本输入对话框？

我尝试了以下代码，在文本区域聚焦时打开文本输入对话框

TextArea address = new TextArea();
        address.focusedProperty().addListener(new ChangeListener<Boolean>() {
            @Override
            public void changed(ObservableValue<? extends Boolean> arg0, Boolean oldPropertyValue, Boolean newPropertyValue) {
                if (newPropertyValue) {
                    System.out.println("Textfield on focus");
                    TextInputDialog dialog = new TextInputDialog("walter");
                    dialog.setTitle("Text Input Dialog");
                    dialog.setHeaderText("Look, a Text Input Dialog");
                    dialog.setContentText("Please enter your name:");
                    // Traditional way to get the response value.
                    Optional<String> result = dialog.showAndWait();
                    if (result.isPresent()) {
                        System.out.println("Your name: " + result.get());
                    }
                } else {
                    System.out.println("Textfield out focus");
                }
            }
        });

TextArea address=newtextarea（）；
address.focusedProperty（）.addListener（新的ChangeListener（））{

public void已更改（observeValue当焦点从对话框返回主舞台时，textarea将再次获得焦点，这将触发再次弹出对话框。您可以从textarea调出焦点以避免此情况：

address.focusedProperty().addListener(new ChangeListener<Boolean>() {
        @Override
        public void changed(ObservableValue<? extends Boolean> arg0, Boolean oldPropertyValue, Boolean newPropertyValue) {
            if (newPropertyValue) {
                System.out.println("Textfield on focus");
                TextInputDialog dialog = new TextInputDialog("walter");
                dialog.setTitle("Text Input Dialog");
                dialog.setHeaderText("Look, a Text Input Dialog");
                dialog.setContentText("Please enter your name:");
                // Traditional way to get the response value.
                Optional<String> result = dialog.showAndWait();
                if (result.isPresent()) {
                    System.out.println("Your name: " + result.get());
                }

                // focus to different node on the scene
                address.getParent().requestFocus();
                // or mySubmitBtn.requestFocus();

            } else {
                System.out.println("Textfield out focus");
            }
        }
    });

address.focusedProperty（）.addListener（新的ChangeListener（））{

public void已更改（ObservalEvalue我已经尝试过此代码，它工作得非常好

 @Override
    public void start(Stage stage) {
        TextArea address = new TextArea();

        address.focusedProperty().addListener(new ChangeListener<Boolean>() {
            @Override
            public void changed(ObservableValue<? extends Boolean> arg0, Boolean oldPropertyValue, Boolean newPropertyValue) {
                TextInputDialog dialog = new TextInputDialog("walter");
                dialog.setTitle("Text Input Dialog");
                dialog.setHeaderText("Look, a Text Input Dialog");
                dialog.setContentText("Please enter your name:");

                if (newPropertyValue) {
                    System.out.println("Old Property : " + oldPropertyValue);
                    System.out.println("New Property : " + newPropertyValue);
                    System.out.println("Textfield on focus");
                    address.getParent().requestFocus();
                    Optional<String> result = dialog.showAndWait();
                    System.out.println("Result :" + result);
                    if (result.isPresent()) {
                        dialog.getDialogPane().requestFocus();
                        System.out.println("Your name: " + result.get());
                    }
                }
            }
        });

        Scene scene = new Scene(new VBox(address), 200, 200);
        stage.setScene(scene);
        stage.show();
        address.getParent().requestFocus();
    }

public void已更改（ObservalEvalue每当我单击对话框时，它的输出为“Textfield out focus”。我无法关闭对话框。我认为它处于某种循环中。@VikasSingh，通过“每当我单击对话框时”您的意思是，右击“取消”或“确定”按钮？添加
地址.getParent（）.requestFocus（））
行，与上面的答案完全相同，然后再试一次。我尝试了与您编写的相同的代码，但不起作用。是的，对话框没有被任何按钮关闭。@VikasSingh我添加了一个完整的示例代码。这样，对话框就不会不断弹出。您是否也可以尝试一下，然后与您的进行比较？
