键盘减少屏幕高度问题 - codenameone

我在一个表单中有TextField，当它聚焦时，会出现一个键盘 . 现在如果我用这个键盘触摸命令，屏幕高度会降低 . 我根据屏幕高度调整了一些填充 . 因此键盘会影响调整 . 如果我再次使用textField转到表单并在没有键盘的情况下触摸图标，则调整就可以了 . 怎么解决？

在表单中搜索文本字段

Container searchContainer = new Container(new BoxLayout(BoxLayout.Y_AXIS));
f.add(searchContainer);

searchTextFieldGroup = new TextField();
searchContainer.add(searchTextFieldGroup);
searchTextFieldGroup.setHint("SEARCH TABLES");
searchTextFieldGroup.setUIID("tableSearchTextField");
searchTextFieldGroup.getAllStyles().setFont(Font.createSystemFont(Font.FACE_SYSTEM, Font.STYLE_ITALIC, Font.SIZE_SMALL));
searchTextFieldGroup.getAllStyles().setBgTransparency(0);
searchTextFieldGroup.getAllStyles().setMargin(2, 2, 2, 2);
searchTextFieldGroup.getAllStyles().setPadding(5, 5, 5, 0);
searchTextFieldGroup.getHintLabel().getAllStyles().setFont(Font.createSystemFont(Font.FACE_SYSTEM, Font.STYLE_ITALIC, Font.SIZE_SMALL));
searchTextFieldGroup.getHintLabel().getAllStyles().setFgColor(0xcccccc);

如果键盘在上面的表单中打开或关闭，屏幕高度会发生变化的主窗体

screenWidth = Display.getInstance().getDisplayWidth();
screenHeight = Display.getInstance().getDisplayHeight();

Container menuContainer;
(mainContainer code......)

int excessHeight = Math.max(screenHeight - t.getPreferredH() - menuContainer.getPreferredH(), 0);
int excessWidth = Math.max(screenWidth - menuContainer.getPreferredW(), 0);
menuContainer.getAllStyles().setPadding(Component.TOP, excessHeight / 2);
menuContainer.getAllStyles().setPadding(Component.BOTTOM, excessHeight / 2);
menuContainer.getAllStyles().setPadding(Component.LEFT, excessWidth / 2);
menuContainer.getAllStyles().setPadding(Component.RIGHT, (excessWidth / 2));
f.revalidate

返回btn点击键盘关闭.............支持键盘打开

如何添加设备键盘取消的高度？

f.addSizeChangedListener(e -> {
    screenWidth = Display.getInstance().getDisplayWidth();
    screenHeight = Display.getInstance().getDisplayHeight();

    int excessHeight1 = Math.max(screenHeight - t.getPreferredH() - menuContainer.getPreferredH(), 0);
    int excessWidth1 = Math.max(screenWidth - menuContainer.getPreferredW(), 0);
    menuContainer.getAllStyles().setPadding(Component.TOP, excessHeight / 2);
    menuContainer.getAllStyles().setPadding(Component.BOTTOM, excessHeight / 2);
    menuContainer.getAllStyles().setPadding(Component.LEFT, excessWidth / 2);
    menuContainer.getAllStyles().setPadding(Component.RIGHT, (excessWidth / 2));
        //Dialog.show("size change", "width " + screenWidth + " height " + screenHeight, "ok", null);
});

orientationChangeListener取消了orientation监听器 . 怎么解决？

f.addOrientationListener(new ActionListener() {
    public void actionPerformed(ActionEvent ev) {
        if (Display.getInstance().isPortrait()) {
            screenWidth = Display.getInstance().getDisplayWidth();
            screenHeight = Display.getInstance().getDisplayHeight();

            menuContainer.getAllStyles().setPadding(0, 0, 0, 0);
            menuContainer.getAllStyles().setMargin(0, 0, 0, 0);

            int excessHeight = Math.max(screenHeight - t.getPreferredH() - menuContainer.getPreferredH(), 0);
            int excessWidth = Math.max(f.getWidth() - menuContainer.getPreferredW(), 0);

            menuContainer.getAllStyles().setPadding(Component.TOP, excessHeight / 2);
            menuContainer.getAllStyles().setPadding(Component.BOTTOM, excessHeight / 2);
            menuContainer.getAllStyles().setPadding(Component.LEFT, excessWidth / 2);
            menuContainer.getAllStyles().setPadding(Component.RIGHT, (excessWidth / 2));
        } else if (!Display.getInstance().isPortrait()) {
            screenWidth = Display.getInstance().getDisplayWidth();
            screenHeight = Display.getInstance().getDisplayHeight();

            menuContainer.getAllStyles().setPadding(0, 0, 0, 0);
            menuContainer.getAllStyles().setMargin(0, 0, 0, 0);

            int excessHeight = Math.max(screenHeight - t.getPreferredH() - menuContainer.getPreferredH(), 0);
            int excessWidth = Math.max(f.getWidth() - menuContainer.getPreferredW(), 0);
            menuContainer.getAllStyles().setPadding(Component.TOP, excessHeight / 2);
            menuContainer.getAllStyles().setPadding(Component.BOTTOM, excessHeight / 2);
            menuContainer.getAllStyles().setPadding(Component.LEFT, excessWidth / 2);
            menuContainer.getAllStyles().setPadding(Component.RIGHT, (excessWidth / 2) - 5);
            f.revalidate();
        }
    }
});
