＆＃34;不要在列表视图中使用edittext＆＃34;这是大多数人所说的......现在我在想应该听取他们的意见。我之前在ListView中添加EditText并遇到与click相关的问题时遇到了问题，我还发布了一个关于此问题的问题（EditText and ListView are not working together），并在（Focus on EditText in ListView when block descendants (Android)）中找到了解决方法。在遇到这么多障碍后，我能够实现这个目标，
但是现在我遇到了回收问题，我在ListView中为EditText添加了一个addTextChangedListener。大多数人都建议使用setOnFocusChangeListener，但这对我来说不是一个选项，因为我必须根据在另一行的EditText中输入的值更改一行的EditText值。 我目前面临的问题是当我在EditText的最后一行输入值时，同样的事情在第一行中反映出来。任何人都可以帮我解决这个问题。 这是代码片段（抱歉英文不好）
