使用onClick显示错误结果的搜索列表视图

Question

我的列表视图正常工作，但我正在使用SearchView在列表视图中查找项目。当我最初点击原始列表视图中的一个项目时，它会显示一个与点击项目有关的对话框，但是搜索完成后，显示的对话框是错误的。更具体地说，它显示了该位置的原始listview项目的对话框。请帮助

Answer 1

你做错了在这里

titlePosition = allTitles.get(position); 
expense = expenseManager.getExpense(titlePosition); 

因为它会从这个位置原来的列表给出的数据。你必须使用适配器类的getItem方法。在那个方法中，由于它已经过滤了数据，因此通过位置更多信息检查here

更新

titlePosition = (String) adapter.getItem(position); 
expense = expenseManager.getExpense(titlePosition); 

试试这个代码。
