无法在 Android Studio 中查看菜单 xml，插件出现异常 Android 支持

Question

每当我打开下面提到的 xml 布局时，Android studio 会显示一条关于插件 Android 支持异常的错误消息。

我遇到的错误

删除行

tools:showIn="navigation_view"

现在可以预览，但在设计选项卡上没有显示

Answer 1

 tools:showIn="navigation_view"  //delete this line

导致布局预览崩溃。

尝试重建项目或关闭项目并重新启动 android studio。

或者先打开另一个xml成功再打开卡住的xml
