我在
Android 6.0,Marshmallow上遇到了日期格式问题.抛出下面提到的异常的代码是我的应用程序用于API请求(“客户端”)的纯Java库(单独构建).该库是用Java 1.6构建的,如果它是相关的…无论如何,这是代码;
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd E hh:mm aa",Locale.UK); Date eventDate = dateFormat.parse(StringUtils.substring(record,23).trim());
……记录有价值;
2015-10-23 Fri 10:59 PM BST 3.60 meters
……“修剪”之后;
2015-10-23 Fri 10:59 PM yyyy-MM-dd E hh:mm aa
这段代码自Froyo的古老时代以来一直有效,并经过单元测试.除了棉花糖之外,抛出异常;

偏移“21”是10:59中’9’之后的空格.谁能解释这个失败?
更新
切换到joda-time,它会发出更多信息错误消息.这里是;
Invalid format ... is malformed at "PM"
…所以,这是关于试图解析的字符串的AM / PM方面 – 回到the docs
解决方法
英国Locale似乎改变了“am”和“pm”的定义.
在Marshmallow,英国Locale现在“am”代表“a.m.”和“下午”由“下午”
String record = "2015-10-23 Fri 10:59 p.m. BST 3.60 meters" SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd E hh:mm aa",Locale.UK); // note the length is 25 now,not 23... Date eventDate = dateFormat.parse(StringUtils.substring(record,25).trim());
我不能解释为什么,但美国地区与上午/下午和英国与上午/下午.
编辑
看来,作为2015年3月Locale更新的一部分,en_gb语言环境已替换其am / pm定义. source diff
