查看支持列表的最佳方法是在最新版本中启动模拟器并打开“自定义语言环境”应用程序。这将列出该版本Android支持的所有语言和语言环境。

从Android 7.0开始，你可以直接从源代码中的语言设置中读取列表。你可以在URL中看到Android版本:

我找到了一个列表，这可能是一个给定的Android版本(API级别)支持的地区的完整列表: 进入android- sdk\platforms\android-[XX]\data\res\values，其中XX表示API级别，然后用任何文本编辑器打开locale_config.xml。 它是人类可读的，如果需要，可以很容易地处理。

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/
