在每个单元格中都带有EditText的Android RecyclerView，在聚焦于编辑文本时提供了奇怪的滚动行为

标签： android android-recyclerview

我有一个视图，其中包含多个水平滚动的回收站视图。每个回收者视图单元格都包含一个EditText控件。当我将回收站视图滚动到右侧并点击EditText框时，回收站将滚动回到左侧的第一个位置。这些文件所包含的主要视图还包含一个EditText。

我正在为回收器视图使用自定义适配器。

我尝试了很多搜索，发现了类似的问题，但没有类似的问题：

Android EditText's container (RecyclerView) auto scroll when EditText is Focused

任何帮助将不胜感激。

这是我所拥有的一个例子： 我的主要布局的一部分包含回收者视图：
