android-studio - 无法在 Android Studio 中编辑/查看布局文件

Question

当我在 android studio 中双击打开一个 android 布局 *.xml 文件时，我在 Android studio 的事件日志中收到一个 AssertionError: null 并且布局编辑器没有打开。

这不会发生在每个项目中，并且开始发生在已经工作正常的项目中，这里是日志错误

null

现在我无法在 Android Studio 中编辑/查看布局文件，有人知道如何解决这个问题吗？

只需从您的事件中删除此行:

tools:showIn="@layout/activity_splash"
