We improved the initial version of yours with adding a listener for KeyEvents and tested it successfully on Android and iOS.

The defocus-method can easily be called at the start of a view, so that it won't automatically focus the first textfield with "Platform.runlater(() -> textField.defocus());".

public class RefocusableTextField extends TextField {

  private Region fakeFocusTarget;

  public RefocusableTextField(String text) {
    this();
    setText(text);
  }

  public RefocusableTextField() {
    fakeFocusTarget = new Region();
    fakeFocusTarget.setManaged(false);
    getChildren().add(fakeFocusTarget);

    addEventFilter(MouseEvent.MOUSE_PRESSED, MouseEvent::consume);

    addEventHandler(MouseEvent.MOUSE_CLICKED, e -> {
      if (!isFocused()) {
        requestFocus();
      } else {
        defocus();
      }
    });

    addEventHandler(KeyEvent.KEY_PRESSED, e -> {
      System.out.println(e.getCode());
      if (e.getCode().equals(KeyCode.ENTER)) {
        defocus();
      }
    });
  }

  public void defocus() {
    fakeFocusTarget.requestFocus();
  }
}
