Java 如何在android中使过滤后的搜索结果显示在listview中

我有一个edittext和一个listview，其中包含数据，因此在edittext中给出关键字后，应该显示listview中的相关关键字。为此，我做了编码。。但在筛选所需项目后。当我单击它时。如果列表包含三个项目aa、bb和cc，它将不会打开该项目示例。如果我搜索cc项目，则在单击它后打开aa项目。因此，请告诉我如何解决此问题

好的，通过阅读描述，我理解的是，因为有三个项目，例如aa、bb和cc，在其中搜索cc返回一个项目，即现在索引为0的cc。单击该按钮时，显示的选定项为aa。问题在于这些指数。您正在使用cc的新索引，它是0，但显示的是旧索引，其中o是aa的索引

几年前，当我遇到这个问题时，我面临着完全相同的问题。我所做的是添加一个额外的字段，将原始索引作为字段存储在对象中。因此，当点击上面示例中的cc时，我会执行类似于cc.getOriginalIndex的操作，该操作将返回2，并显示打印结果

如果这对您有意义，请尝试实现它，否则我们将进入代码。

您应该正确设置代码格式，以便于其他人阅读。无论如何，您可能会发现这个答案很有用：
