当我 select 项目时，同一片段、持有人或数据库的两个回收者视图带来错误数据
Two recycler view on same fragment, holder or db brings wrong data when I select item
如标题我无法获得正确的项目数据，现在假设我的主要片段上有 2 个回收视图列表，一个回收视图是垂直的，另一个是水平的。如果我只使用一个回收站，一切正常。但是当我添加另一个时，它会随机打开项目，但随机数据打开只会随机两个回收站的位置。就像我的第一个回收商有 [a,b,c,d] 一样，其他回收商有 [e,f,g,h]。当我单击第一个回收器的第一项时，它会转到显示详细信息的其他片段，它的开头是 e 而不是 a，如果我返回并重试，它会再次打开 e，重试，它是 a !!所以它随机打开，为什么会这样 为什么我不能打开正确的数据？我将 Log.d 放在我的适配器上，当我单击回收器项目时，适配器日志显示你单击了“a”，但我的详细信息片段显示了“e”的数据。我做错了什么？这是我的代码：（我有很多代码所以我分享我们需要的）

就像我说的，如果我删除我的一个回收器视图，它的工作完美，但如果我在同一个片段上使用两个回收器，我得到了错误的数据。日志说我打开了正确的数据，但事实并非如此。
如果你需要我的其他代码来解决问题，请告诉我，我有很多屏幕不知道我需要分享哪一个来解决它。
我解决了我的问题，但我不知道我在后台更改了什么
我只是在 MovieListesiViewmodel 中将我的一个函数分成两个函数并提供了一个参数，它的工作就像奇迹一样

就像我说的，如果我删除我的一个回收器视图，它的工作完美，但如果我在同一个片段上使用两个回收器，我得到了错误的数据。日志说我打开了正确的数据，但事实并非如此。 如果你需要我的其他代码来解决问题，请告诉我，我有很多屏幕不知道我需要分享哪一个来解决它。
我解决了我的问题，但我不知道我在后台更改了什么 我只是在 MovieListesiViewmodel 中将我的一个函数分成两个函数并提供了一个参数，它的工作就像奇迹一样
