Question

如何将键盘置于屏幕底部？电路板已经显示后，我只有键盘/ PopupWindow的大小。在调用show（）之前，每个函数都返回0.0以获得所请求的宽度。如果我之前知道宽度，我可以正确设置位置。键盘大小可能会在以后更改，这就是我无法使用设置大小进行操作的原因。我正在使用fx-onscreen-keyboard

我的小服务：

public class KeyboardService {

private double screenWidth = Screen.getPrimary().getVisualBounds().getWidth();
private double screenHight = Screen.getPrimary().getVisualBounds().getHeight();
private double keyboardPosX = 0.0;
private double keyboardPosY = 0.0; 

private KeyBoardPopup keyboardPopup;

public KeyboardService() {
    keyboardPopup = KeyBoardPopupBuilder.create().initLocale(Locale.GERMAN).build();
    keyboardPopup.setAutoHide(true);
    keyboardPopup.setConsumeAutoHidingEvents(false);
    keyboardPopup.getKeyBoard().setScale(2.5);
    keyboardPopup.getKeyBoard().setLayer(DefaultLayer.DEFAULT);

    keyboardPopup.getKeyBoard().setOnKeyboardCloseButton((e) -> {
        keyboardPopup.hide();
    });

}

public void showKeyboard(Node node){
    keyboardPosX = (screenWidth - keyboardPopup.getWidth())/2;
    //keyboardPosX = (screenWidth - keyboardPopup.getKeyBoard().getWidth())/2;
    keyboardPosY = screenHight;
    keyboardPopup.show(node, keyboardPosX, keyboardPosY);
}}

键盘的宽度是在布置了弹出窗口的弹出窗口时定义的，当你调用show后会发生什么。

执行此操作的简单方法是收听widthProperty的{{1}}，获取新值，然后相应地移动弹出窗口。

这样做：

KeyBoardPopup
