使用 Phonegap 将字母滚动条添加到 Android 应用程序中的列表视图答案

【问题标题】：Add Alphabetical Scroll Bar to List View in an Android App Using Phonegap使用 Phonegap 将字母滚动条添加到 Android 应用程序中的列表视图

【问题描述】：

我是 android 应用开发的新手，我目前正在构建一个简单的歌本应用，主页上的列表视图显示歌曲列表。点击歌曲将带您进入包含歌词的页面。

我正在使用 Dreamweaver CC 和 Phonegap。这是一个非常简单的过程，我已经完成了一切。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。

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>
        <li data-role="list-divider" data-theme="c">C</li>
            <li><a href="#page2">A Common Love</a></li>
            <li><a href="#page3">Song 2</a></li>

</div>

我已经在网上找了几个小时了，但我没有找到可以工作的好解决方案。我对字母表中的每个字母都使用了列表分隔符。我可以设置一个滚动条来导航到每个列表分隔符吗？

在我的列表中添加按字母顺序排列的滚动条的最佳方式是什么？

谢谢！
