错误的位置列表视图

问题描述：

所以我有回收站视图，显示带有选项的json来搜索该列表。在搜索之前，当点击特定列表项目时，我会获得显示有关该项目详细信息的新活动。问题是当我搜索列表并点击项目时，我得到错误的细节。示例如果搜索结果位于第一位（顶部列表视图项），当我点击它时，我从搜索前存在的项目获取数据。如何解决这个问题？错误的位置列表视图

答

我猜问题是，“ViewHolder”类只初始化一次，你在哪里设置你的“ClickListener”来的意见。但问题是，您将完整的数组传递给“ViewHolder”，并且未将已过滤的数组传递给“ViewHolder”，因为它已初始化一次。因此，当您获得点击位置的数据时，它将返回来自主数组列表的数据，而不是来自已过滤数据的数据。

所以来解决方法，设置您的“ClickListener”在“onBindViewHolder”方法而不是ViewHolder类中查看，因为每次您与列表或数据更改交互时都会调用它。希望它能为你工作。
