推荐答案

它作为唯一的字符串值不要求是不可能的。因此，你不能获得ID后面是潜在你可以有多个ID映射到相同的字符串。

It's not possible as the string values are not required to be unique. Therefore you can't get "the id" back as potentially you could have multiple ids mapping to the same string.

例如：

<string name="text">Chennai</string>
<string name="text2">Chennai</string>
<string name="text3">Chennai</string>

是完全可以接受的。你怎么能得到的ID后面的字符串奈？

is completely acceptable. How can you get "the id" back for the string "Chennai"?
