我怎样才能在android studio中解决这类问题？

Question

创建新项目后，我收到以下错误

Error:Failed to resolve: com.android.support:design:23.+
Install Repository and sync project 
Show in Project Structure dialog

Error:Failed to resolve: com.android.support:appcompat-v7:23.4.0
Install Repository and sync project
Show in Project Structure dialog

这是截图

我找到了一些有关此问题的信息。之后，我搜索了Android支持存储库和Google存储库的更新。我找到了Google存储库的更新并对其进行了更新。现在我的所有SDK和工作室都已更新。

我现在如何处理此错误？
