原答案:

从Android 5.0开始，BCP 47中的所有语言都可以用于应用程序开发(不过，在给定设备的系统设置中，这些语言可能并不一定可以选择)。当使用ISO 639-1代码时，资源文件夹的格式值为-xx…其中xx为ISO-639-1代码。

当使用BCP 47标记时，资源文件夹命名为values-b+xxx…其中XXX是三个字母的语言代码。

以下是Android 2.3之前的列表

The Hebrew (“he”) >language code is rewritten as “iw”, Indonesian (“id”) as “in”, and Yiddish (“yi”) as “ji”. This rewriting happens even if you construct your own Locale object, not just for instances returned by the various lookup methods. See also https://issuetracker.google.com/issues/36908826.

首先，我们需要计划应用程序如何在不同的局部环境中呈现不同的效果。 这里它展示了一个例子，文本字符串和图像必须去哪里。

de-rDE German / Germany res/values-de/ res/drawable-de-rDE/ 
fr-rFR French / France res/values-fr/ res/drawable-fr-rFR/ 
fr-rCA French / Canada res/values-fr/ res/drawable-fr-rCA/ 
en-rCA English / Canada (res/values/) res/drawable-en-rCA/ 
ja-rJP Japanese / Japan res/values-ja/ res/drawable-ja-rJP/ 
en-rUS English / United States (res/values/) res/drawable-en-rUS/
