我在运行问答游戏时出错。像这样的东西(打开游戏 Activity 时)。我的应用程序停止，我在第 0 行出现二进制 XML 文件错误。这有点奇怪，因为我没有在第 0 行看到这样的问题，所以我需要大家的帮助。谢谢!

问题出在哪里？
最佳答案
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，不 颜色引用，并且 View 试图将您在 xml 中传递的引用值转换为颜色，它会抛出一个异常(exception)，所以你只能为这个属性使用颜色(像这样:#000000)或者 fork 项目并修改 attrs.xml像这样:
<attr name="buttonColor" format="color|reference" />
