如何在Android recyclerview中停止搜索过滤器上的持续崩溃

问题描述

每当我在searchview中进行搜索时，我一直在努力阻止索引超出范围异常崩溃.我尝试了网上列出的几件事:在搜索中使数组脱离索引绑定异常

I have been struggling to stop an index out of bounds exception crash every single time I do a search in a searchview. I tried a couple of things listed online :on search getting array out of index bound exception

https ://www.codeproject.com/Questions/1040119/Android-app-is-crashing-with-Index-out-of-range-is

但到目前为止没有任何帮助.这个问题是我的代码特有的，只是无法弄清楚是什么问题.

but nothing helped so far. The issue is something specific to my code, just can't figure out what's the issue.

这是我的崩溃报告:

任何想法我可能会丢失或未正确执行的操作，始终会崩溃，并显示:java.lang.IndexOutOfBoundsException:检测到不一致.项目位置为0(offset:0)无效."(有时为16或其他一些数字，通常会在我输入搜索视图并且过滤器搜索匹配的字符时发生)

Any idea what I could be missing or not doing correctly, that it always crashes with ":java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid item position 0(offset:0)."(sometimes 16 or some other number, usually happens when i type in the searchview and the filter searches through the matching characters)

乐于分享更多代码或在必要时进行详细解释.已经为此苦苦挣扎了好几天，但没有运气:(

Happy to share more code or explain in detail if necessary. Have been struggling with this for days ,but no luck :(

推荐答案

Filter实现存在问题.您正在使用performFiltering(CharSequence charSequence)方法更新mSearchGuestListResponseListFiltered，它是错误的根源.您必须使用publishResults(CharSequence charSequence, FilterResults filterResults)方法更新列表.因此，您必须从适配器代码中删除mSearchGuestListResponseListFiltered = filteredList;(第234行).

此外，您在getItemId()和onBindViewHolder()方法中调用了notifyItemChanged()方法.我认为这也是错误的实现，应该删除它们.

There is a problem with Filter implementation. You are updating mSearchGuestListResponseListFiltered in the performFiltering(CharSequence charSequence) method and it's source of the error. You must update your list in publishResults(CharSequence charSequence, FilterResults filterResults) method. So you must remove mSearchGuestListResponseListFiltered = filteredList; (Line 234) from your adapter code.

In addition, you called notifyItemChanged() method in getItemId() and onBindViewHolder() methods. I think it's wrong implementation as well and you should remove them.
