android - 更新 gradle 依赖项后呈现问题

Question

我刚刚更新了 build.gradle(Module: app) 依赖项，之后在 Android Studio 上出现了渲染问题。出了什么问题，在更新依赖项之前，everythink 工作正常

现在是这样的:

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:design:23.0.0'
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'com.google.android.gms:play-services:7.8.0'
    compile 'com.android.support:support-v4:23.0.0'

    compile 'com.android.support:recyclerview-v7:23.0.0'
}

my_activity.xml

            </android.support.design.widget.CollapsingToolbarLayout>
        </android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

出现这个错误:

Rendering Problems Missing styles. Is the correct theme chosen for this layout?      

Use the Theme combo box above the layout to choose a different layout, or fix the theme style references.  

The following classes could not be instantiated:
    - android.support.design.widget.CollapsingToolbarLayout (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
