#鸿蒙通关秘籍#如何动态调整列表高度以适应新闻标题的高度变化？

通过监听新闻标题的onAreaChange事件来动态计算新闻列表的高度，从而保持滚动效果的稳定。当新闻标题的高度变化时，重新计算新闻列表的高度，确保联动滚动的效果。

Text(this.currentPlayNews.newsName)
    ...
    .onAreaChange((oldValue: Area, newValue: Area) => {
        if (oldValue.height !== newValue.height) {
            const newsNameHeight = newValue.height as number;
            const videoCardVerticalMargin = Constants.VIDEO_CARD_MARGIN_TOP + Constants.VIDEO_CARD_MARGIN_BOTTOM;
            const videoCardHeight = newsNameHeight + Constants.VIDEO_CONTROL_HEIGHT;
            this.newsListHeight = this.scrollHeight - videoCardHeight - videoCardVerticalMargin;
        }
    })
