android - getQuantityString 没有用值替换格式

Question

我想使用复数资源来生成像 "9" 这样的带引号的数字。

在我的 plurals.xml 中:

<plurals name="posts">
  <item quantity="other">\"%dd\"<\item>
</plurals>

代码:

String text = res.getQuantityString(R.plurals.posts, meUser.postCount); 

postCount为9时，为什么text是"%dd"而不是"9"？

Answer 1

来自 the Android docs:

When using the getQuantityString() method, you need to pass the count twice if your string includes string formatting with a number. For example, for the string %d songs found, the first count parameter selects the appropriate plural string and the second count parameter is inserted into the %d placeholder. If your plural strings do not include string formatting, you don't need to pass the third parameter to getQuantityString.

即res.getQuantityString(R.plurals.numberOfSongsAvailable, count, count);
