问题出在哪里？
【问题讨论】：
这里：info.hoang8f.widget.FButton.parseAttrs(FButton.java:116) 删除您的应用构建文件夹，制作项目并再次运行。 @pskink 所以这是库错误？ @HemantParmar 没用 我不知道 FButton.java 是你的类还是它属于任何库——你更清楚 【参考方案1】：尝试删除cornerRadius属性导致问题可能是库问题
fbutton:cornerRadius="10dp"
删除所有按钮，效果很好
【讨论】：
【参考方案2】：问题出在库本身，如果你检查attrs.xml：
<attr name="buttonColor" format="color" />
如您所见，buttonColor 只接受颜色值，NOT 颜色引用，并且视图正在尝试将您在 xml 中传递的引用值转换为颜色并引发异常，所以您只能对这个属性使用颜色（这样：#000000）或者fork项目并像这样修改attrs.xml：
<attr name="buttonColor" format="color|reference" />
【讨论】：
fbutton:shadowColor 也必须更改
