Android Studio, Rendering problems
我刚刚安装了 Android Studio，但当我启动时它告诉我：
呈现问题无法实例化以下 类：
android.support.design.widget.FloatingActionButton (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

我能做什么？
只更新SDK即可解决问题。您可以通过 Android studio->Help->Check for Update-> 并单击 Update now 或打开 SDK 文件夹并手动 运行 'SDK Manager.exe' 更新所有可用的 SDK 更新。有时 Android studio 会更新，但 SDK 不会。手动更新SDK。 （在桌面上保留 'SDK Manager.exe' 的快捷方式将是一个有用的提醒）。
