android中的Plurals（Quantity Strings）类型

From:http://blog.csdn.net/ltl451011/article/details/6947642

不同的语言对数量的定义有不同的语法规则。例如，在英语中，1个指的是一种特殊情况。其他时候我们说n个。这种单数和复数的情况非常的普通。但其他语言却有明显的区别。Android中设置了0，1，2，"很少"，“许多”和“其他”做为数量表述。

对于给定的语言和数量，决定使用那种情况是非常的困难和复杂的。Android提供了getQuantityString()来帮助我们决定选择适当的资源。

语法：

<span class="pun"><?</span><span class="pln">xml version</span><span class="pun">=</span><span class="str">"1.0"</span><span class="pln"> encoding</span><span class="pun">=</span><span class="str">"utf-8"</span><span class="pun">?></span><span class="pln">
</span><span class="tag"><</span><a target=_blank href="http://developer.android.com/guide/topics/resources/string-resource.html#plurals-resources-element"><span class="tag">resources</span></a><span class="tag">></span><span class="pln">
    </span><span class="tag"><</span><a target=_blank href="http://developer.android.com/guide/topics/resources/string-resource.html#plurals-element"><span class="tag">plurals</span></a><span class="pln">
        </span><span class="atn">name</span><span class="pun">=</span><span class="atv">"</span><em><span class="atv">plural_name</span></em><span class="atv">"</span><span class="tag">></span><span class="pln">
        </span><span class="tag"><</span><a target=_blank href="http://developer.android.com/guide/topics/resources/string-resource.html#plurals-item-element"><span class="tag">item</span></a><span class="pln">

            </span><span class="tag">></span><em><span class="pln">text_string</span></em><span class="tag"></item></span><span class="pln">
    </span><span class="tag"></plurals></span><span class="pln">

文件位置：res/values/filename.xml
如何引用：R.plurals.plural_name

<?xml version="1.0" encoding="utf-8"?>
<resources>
