更新的gradle依赖项后呈现问题

我刚刚更新了build.gradle(Module:app)dependecies,之后在Android Studio上出现了渲染问题。 有什么不对,在更新依赖关系之前,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

           

并得到这个错误:

 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 Exception Details android.content.res.Resources$NotFoundException  at com.android.layoutlib.bridge.android.BridgeContext.obtainStyledAttributes(BridgeContext.java:620)  at com.android.layoutlib.bridge.android.BridgeContext.obtainStyledAttributes(BridgeContext.java:108) Failed to find style with id 0x7fff00e4 in current theme (3 similar errors not shown) 

单击“使用Gradle文件同步项目”选项:

工具 – > Android – >使用Gradle文件同步项目

如果失败,请尝试运行“重建项目”:
