在学习《第一行代码》过程中用android studio 新建工程，出现如下错误



经查阅错误代码，发现是gradle的版本导致的错误

参考Android Studio FloatingActionButton error

将app-src-build.gradle中的

compile 'com.android.support:appcompat-v7:23.2.0'
compile 'com.android.support:design:23.2.0'

修改为

compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:design:23.1.0'

然后rebuild project 刷新游戏design界面，bug就消失了
