使用Phonegap将字母滚动条添加到Android应用程序的列表视图中

我是android应用程序开发的新手，目前正在构建一个简单的歌曲书籍应用程序，在主页上显示歌曲列表。点击歌曲会带你进入一个有歌词的页面

我正在使用Dreamweaver CC和Phonegap。这是一个非常简单的过程，我几乎完成了所有的事情。我只需要像大多数列表应用程序一样，在列表的右侧添加一个按字母顺序排列的滚动条

以下是我的索引页代码：

<div id="page" data-role="page">
<div data-role="header">
  <h1>Song Book</h1>
</div>
<div data-role="content">   
    <ul data-role="listview">
        <li data-role="list-divider" data-theme="c">A</li>
            <li><a href="#page2">A Common Love</a></li>
            <li><a href="#page3">Song 2</a></li>
            <li><a href="#page4">Song 3</a></li>

我已经在网上找了好几个小时了，但我没有找到一个好的解决方案，我可以开始工作。我对字母表中的每个字母都使用了列表分隔符。我可以设置滚动条导航到每个列表分隔符吗

在我的列表中添加字母滚动条的最佳方式是什么

谢谢

有可能，但我想知道对于如此小的屏幕，它是否能顺利导航

html

JS

拨弄
