我有jQuery UI datepicker的以下代码:

$(function() {
        $(".date").datepicker({
            showOn: 'button',
            buttonText: "Choose Date",
            dateFormat: 'yy-mm-dd'
        });
    });

它会在文本框的侧面创建一个按钮,以便人们可以单击该框并选择日期.是否可以将类应用于创建的按钮,以便我可以应用CSS样式？

我刚刚更新到 Android Studio 4.1，启动时抛出以下问题：
