Add appcompat-v7 library as dependency to the design library project. It resolve the same error for me. I think it helps you.
添加 appcompat-v7 库作为设计库项目的依赖项。它为我解决了同样的错误。我认为这对你有帮助。

I was able to fix the issue with @igece solution, but later I found out that the real issue is an outdated appcompat-v7 library.
我能够用@igece 解决方案解决这个问题，但后来我发现真正的问题是一个过时的appcompat-v7 library.
After upgrading it to the latest versionnothing had to be edited on Google's libraries.
将其升级到最新版本后，无需在 Google 的库中编辑任何内容。

Seems to be solved adding the formatattribute to both backgroundTintand backgroundTintModeitems in /res/values/attrs.xml:
似乎可以解决将format属性添加到backgroundTint和 中的backgroundTintMode项目/res/values/attrs.xml：
Before:
前：
<declare-styleable name="FloatingActionButton">
<!-- Background for the FloatingActionButton -->
<attr name="android:background"/>
<attr name="backgroundTint"/>
<attr name="backgroundTintMode"/>
After:
后：
<declare-styleable name="FloatingActionButton">
<!-- Background for the FloatingActionButton -->
<attr name="android:background"/>
<attr name="backgroundTint" format="color"/>
<attr name="backgroundTintMode" format="integer"/>

Adding appcompat-v7 library in dependancy of design library project is the solution for this issue if you have already installed updated Android Support Repository and Google Play Services.
如果您已经安装了更新的 Android Support Repository 和 Google Play Services，则在设计库项目的依赖项中添加 appcompat-v7 库是解决此问题的方法。

I wanted to add this as comment under third answer, but code was not formatted properly. I have to add both dependencies below to resolve the issue:
我想将此添加为第三个答案下的评论，但代码格式不正确。我必须在下面添加两个依赖项才能解决问题：
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'
