Android 美国各州数据提供商
我有一个非常常见的用例。用户需要输入他们的地址（如果他们选择不使用反向地理位置）。
对于其中的州部分，我希望他们能够从列表中选择他们的州。对于 Android，似乎很容易拥有一个内容提供商来为所有应用程序提供此常见用例的功能。有这样的东西是预先建好的吗？或者我是否必须创建自己的内容提供商？我知道 ISO 维护着一份很好的国家及其州列表（我相信是权威机构和下属机构？）。
I have a very common use case. The user needs to enter their address (if they choose not to use reverse geo-location).
For the state portion of this, I want them to be able to select their state from a list. With Android, it seems as if it would be easy to have a content provider which provides the functionality for this common use case to all applications. Is there such a thing pre-built? Or am I going to have to create my own content provider? I know ISO maintains a nice list of countries and their states (Authority and Subauthoriy I believe?).

您没有说明您对哪个国家/地区感兴趣，或者该国家/地区是否可以在您的应用程序中更改。
如果您谈论的是美国，我想说您可以使用硬编码的州列表< /a>.我们不打算吞并任何新的国家，在内战爆发 150 周年之际，有人脱离联邦的可能性很小。
You don't say which country you're interested in, or if the country can change within your app.
If you're talking about the United States, I'd say that you can get away with a hard-coded list of states. We aren't planning to annex any new ones, and the chances of somebody seceding from the Union are small in this 150th anniversary year of the start of the Civil War.
