Android Studio 1.4 Rendering Issues in the New Box Template

Question

I just upgraded to Android Studio 1.4. I created a new project with the target SDK installed in Marshmellow. When I create a new activity in the navigation box, I can simply start the operation on the virtual device. However, none of the XML layouts appear in the preview area.

Here are the errors: activity_main.xml:

Display Issues There are no styles. Is the right theme chosen for this layout? Use the Theme combo box above the layout to select a different layout or fix links to the theme style. NOTE. One or more layouts lacks the layout_width or layout_height attributes. They are required in most layouts. Or: Automatically add all missing attributes. The following classes cannot be created: - android.support.design.widget.NavigationView (Open Class, Show Exception, Clear Cache) Tip. Use View.isInEditMode () in your custom views to skip code or show sample data if shown in the IDE exception details.
