我已经使用 jquery mobile 设计了 android phonegap 应用程序。我需要显示弹出窗口并设置 jquery mobile 弹出窗口的高度。我给出了溢出：css 中的滚动和弹出内容在 android 4.0 中滚动，但在 android 中没有滚动2.2.
这是我的代码
<div align="center">
<a href="#popupBasic" data-rel="popup">Pop Up</a>
</div>
<div data-role="popup" id="popupBasic" data-dismissable="false" data-theme="c" data-overlay-theme="c" >

</div>
CSS：
.ui-popup { 位置：相对；高度：100px；溢出：滚动；}
请指导我。在此先感谢。
