Java 过滤器上的RecyclerView位置

我有一个RecyclerView，它显示CardView，其中包含来自SQLite数据库的一系列信息，如地址、lat、long等。当我在“活动”中引入一个过滤器以按地址\名称搜索时，它并没有完全正确地进行过滤。它确实按地址名称过滤，但其余信息（如lat long等）将从列表中的第一项显示，而不是从应该与地址名称对应的项显示

我尝试了以下操作（您将在onClickListener中看到），但也没有帮助：

int adapterPosition = holder.getAdapterPosition();

你知道如何正确显示位置吗？ 代码如下。谢谢你

        String input = newText.toLowerCase();
        ArrayList<String> newList = new ArrayList<>();
        for (String addressname : DBaddress_name) {
            if (addressname.toLowerCase().contains(input)) {
                newList.add(addressname);
            }
        }
        customerAdapter.updateList(newList);

您只是在传递地址名并在适配器内更新此列表，这就是其他值没有得到更新的原因，您还必须传递其他列表以正确更新它们。

您需要创建一个POJO类，该类保存要在每个

RecyclerView

项中显示的数据的字段；不需要将不同的列表传递给适配器，只需将此POJO的单个列表传递给RecyclerView；这将正确反映任何过滤，因为所有列表都合并到一个列表中

因此，您必须替换下面的

private ArrayList<String> address_id, address_timestamp, address, address_lat, address_long, address_name;

---

谢谢在onQueryTextChange中，实现这一点的最佳方法是什么？您好，谢谢，我现在已经将完整的适配器类和活动重新编写为POJO。这很简单。不过，还是不太确定如何过滤？@warfo09谢谢你的评论，我刚刚在更新部分更新了答案。。希望它能解决
