我在运行问答游戏时出错。这样的事情（打开游戏活动时）。我的应用程序停止，并在第0行上显示了二进制XML文件错误。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？

Answer 1

问题出在库本身，如果您检查attrs.xml：

<attr name="buttonColor" format="color" />

如您所见，buttonColor唯一接受颜色值， 不
接受颜色引用，并且视图试图将您在xml中传递的参考值转换为颜色，并且抛出异常，因此您只能将此颜色用于此属性（ 例如：＃000000
）或派生项目并按如下所示进行修改attrs.xml：

<attr name="buttonColor" format="color|reference" />
