I've tried many combinations of escape sequences to get an exclamation point into an xml string in Android's resource folder - to no avail. What xml string would you use for Help! for example? Thanks...

推荐答案

XML 文件应该接受感叹号，除非可能紧跟在左尖括号之后.

An XML file should accept a exclaimation point, except possibly immediately after a open angle bracket.

如果真的拒绝，你应该可以使用数字实体:Help! = Help!

If it really refuses, you should be able to use a numeric entity: Help! = Help!
