本文探讨了在不同语言环境下如何正确使用复数形式的字符串资源。特别关注了中文环境中复数形式的区别并不明显的问题，并指出不应将复数字符串用于如邮件提示等非复数应用场景。

	<plurals name="unicornCount">
	    <item quantity="one">One unicorn</item>
	    <item quantity="other">%d unicorns</item>
	</plurals>

String s = getResources().getQuantityString(R.plurals.unicornCount, 1, 1);
		Log.d(this.getClass().getName(), s);
		s = getResources().getQuantityString(R.plurals.unicornCount, 3, 3);
		Log.d(this.getClass().getName(), s);

因为中文没有复数语法，所以当语言是中文时，将总是获得quantity为other的字符串

Although historically called "quantity strings" (and still called that in API), quantity strings should only be used for plurals. It would be a mistake to use quantity strings to implement something like Gmail's "Inbox" versus "Inbox (12)" when there are unread messages, for example. It might seem convenient to use quantity strings instead of an "if" statement,but it's important to note that some languages (such as Chinese) don't make these grammatical distinctions at all, so you'll always get the "other" string.
