能解决我的问题吗。最后经过 2 天的努力，我清楚地得到了 70% 的输出。Exp：我有哪些数据来自服务器的列表视图。在列表视图中有一些文本、按钮和滚动索引 A、BC、D、E、F、G。
问题：按钮不起作用意味着当我单击它时...如果添加以下代码。它看起来像下面的图像：
在这里，我以这种方式使用了 XML ---> com.woozzu.android.widget.IndexableListView 在这种情况下，按钮 ONCLICK 不起作用 滚动视图 A、B、C 以正确的方式显示并且工作正常..

状态2：-
在这种情况下，单击按钮工作正常，但滚动视图 A、B、C 也工作正常，但在侧面将没有字母 A、B、C、D、E、F、G ... 如果我在其中添加列表视图homempleb.xml，那么两者都可以正常工作，但没有图像中显示的字母索引。我希望按钮和滚动索引都像上面的图片一样工作。我不擅长这个主题。请帮助我它以这种方式显示：
