我想在ScrollVIEw中使用ExpandableListVIEw和其他视图,但我遇到了ExpandableListVIEw中的自动滚动问题,我试图禁用它,但问题在于ExpandableListVIEw的高度及其内部的布局.
所以我想
>禁用ExpandableListVIEw滚动
>调整ExpandableListVIEw&的大小包含groupVIEw时包含的linearLayout
我搜索了一个解决方案,我找到了一个仅适用于ListVIEw的解决方案
Listview in ScrollView
我想使用ExpandableListVIEw(使用自定义适配器)进行相同的锻炼.
这是我的代码：

在具有滚动功能的另一个视图中放置具有自己的滚动功能的视图总是一个非常糟糕的主意.这可能导致触摸 *** 作被错误的视图,糟糕的性能等拦截.此外,从您的主布局中,除了使用列表视图进行TextVIEw滚动之外,您似乎没有使用ScrollVIEw.为什么不将它添加为标题视图？ expListVIEw.setheaderVIEw(VIEw)并将textvIEw扩展到其中.
