为什么android xml文件名必须只包含小写字母和数字（[a-z0-9_。]）？

Question

I am usually name my file in camelCase (like tabActive ). But it is not allowed in Android.

Is there any reason why android xml file name must contains only lowercase letters and digits ([a-z0-9_.])?

/home/trungdq/.../res/drawable/tab-active.xml: Error: Invalid file name: must contain only lowercase letters and digits ([a-z0-9_.])

Answer 1

It's simple: out of xml filenames the Java constants get generated. The later have very strict rules about how they may be built

Answer 2

您可以这样认为，如果xml名称支持大写AZ，但程序如何区分“Activity_Main_Layout.xml”和“activity_main_layout.xml”，当您在代码中使用xml文件时，很难理解。
