error: No resource identifier found for attribute ‘footerColor’ in package

异常提示:

使用自定义控件，引用包名应该是AndroidManifest.xml中所定义的包路径，并非src下.java文件所指向的包，这个容易犯错！

否者Android studio 中的xml布局界面，运行后会提示以下错误:

error: No resource identifier found for attribute ‘footerColor’ in package

一般情况下，加上这一句就可以了，特殊情况下，再根据上边那种实现

xmlns:app="http://schemas.android.com/apk/res-auto"

参考xml
