使用Phonegap将按字母顺序排列的滚动条添加到Android应用程序中的列表视图



我是Android应用程序开发的新手，我目前正在构建一个简单的歌书应用程序，主页上的列表视图显示歌曲列表。单击歌曲将带您进入带有歌词的页面。

我正在使用 Dreamweaver CC 和 Phonegap。这是一个非常简单的过程，我已经完成了所有工作。我只需要像大多数列表应用程序一样在列表右侧添加一个按字母顺序排列的滚动条。

这是我的索引页代码：

<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>
        <li data-role="list-divider" data-theme="c">B</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>

我已经在网上寻找几个小时了，但我没有找到一个可以工作的好解决方案。我为字母表的每个字母使用了一个列表分隔符。我可以设置滚动条以导航到每个列表分隔符吗？

将

按字母顺序排列的滚动条添加到我的列表中的最佳方法是什么？

谢谢！

可能，但我想知道对于这么小的屏幕来说，导航是否流畅
