鸿蒙有没有这个工具displayutils

 private void addBottomLine() {
        Component line = new Component(getContext());
        // 目前不支持直接设置背景颜色，只能通过Element来设置背景
        ShapeElement element = new ShapeElement();
        element.setShape(ShapeElement.RECTANGLE);
        element.setRgbColor(barBottomLineColor);
        line.setBackground(element);
        LayoutConfig config = new LayoutConfig(ComponentContainer.LayoutConfig.MATCH_PARENT,
                DisplayUtils.vp2px(getContext(), barBottomLineHeight));
        // 位于底部
        config.alignment = LayoutAlignment.BOTTOM;
        config.setMarginBottom(DisplayUtils.vp2px(getContext(), barBottomHeight - barBottomLineHeight));
        line.setAlpha(barBottomAlpha);
        addComponent(line, config);
    }
