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:

https://android.googlesource.com/platform/frameworks/base/+/android-9.0.0_r1/core/res/res/values/locale_config.xml https://android.googlesource.com/platform/frameworks/base/+/android-8.1.0_r1/core/res/res/values/locale_config.xml https://android.googlesource.com/platform/frameworks/base/+/android-8.0.0_r1/core/res/res/values/locale_config.xml https://android.googlesource.com/platform/frameworks/base/+/android-7.1.2_r1/core/res/res/values/locale_config.xml https://android.googlesource.com/platform/frameworks/base/+/android-7.0.0_r1/core/res/res/values/locale_config.xml

谷歌播放描述的列表是不同的:

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。

API 22 (Android 5.1)支持的地区列表。从区域设置为“英语(美国)”的Nexus 5获取(语言环境影响DisplayName输出)。

for (Locale locale : Locale.getAvailableLocales()) {
    Log.d("LOCALES", locale.getLanguage() + "_" + locale.getCountry() + " [" + locale.getDisplayName() + "]");
}

我认为最好的方法是运行一个示例代码来查找受支持的地区。 我已经做了一个代码片段，它:

final Locale[] availableLocales=Locale.getAvailableLocales();
for(final Locale locale : availableLocales)
  Log.d("Applog",":"+locale.getDisplayName()+":"+locale.getLanguage()+":"
    +locale.getCountry()+":values-"+locale.toString().replace("_","-r"));

这些列是:displayName(它对用户的外观)，locale，变量，以及开发人员应该将字符串放入的文件夹。

下面是我用5.0.1模拟器制作的表格: https://docs.google.com/spreadsheets/d/1Hx1CTPT82qFSbzuWiU1nyGROCNM6HKssKCPhxinvdww/

奇怪的是，在某些情况下，我得到了“#”，这是我以前从未见过的东西。它可能很新，我选择的规则对于这些情况可能是不正确的(尽管当我放入这样的文件夹和文件时，它仍然编译良好)，但对于其他情况应该没有问题。

如果有人知道“#”是什么，以及如何处理它，请告诉我。
