两个提示一个是

一个是
Failed to instantiate one or more classes:

- android.su



pport.v7.widget.ActionBarContextView (Open Class, Show Exception, Clear Cache)

Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE. If this is an unexpected error you can also try to build the project, then manually refresh the layout.
