Question

我正在从http://developer.android.com/training/basics/firstapp/starting-activity.html开始执行Android first app教程。

我正在尝试使用FloatingActionButton，但Android Studio无法识别它。

我添加了这个导入：

import android.support.design.widget.FloatingActionButton;

但它也没有找到。

我是否需要添加任何其他依赖项？

如果我将compile 'com.android.support:design:23.2.1'添加到模块的build.gradle，我会得到：

Error:A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugCompile'.
   > Could not find com.android.support:design:23.2.1.
