Android SimpleDataFormat未在KitKat中生成月份名称
在KitKat中,以下日期格式化程序生成错误的结果。是我还是凯特 对于除KitKat之外的所有版本,以下代码生成预期的“April 27”。然而,在KitKat上,它记录了“A 27”。我签入调试器以验证这不是布局问题-SimpleDataFormat创建的字符串是“a 27”Android SimpleDataFormat未在KitKat中生成月份名称,android,simpledateformat,android-4.4-kitkat,Android,Simpledateformat,Android 4.4 Kitkat,在KitKat中,以下日期格式化程序生成错误的结果。是我还是凯特 对于除KitKat之外的所有版本,以下代码生成预期的“April 27”。然而,在KitKat上,它记录了“A 27”。我签入调试器以验证这不是布局问题-SimpleDataFormat创建的字符串是“a 27” SimpleDateFormat dateOnyFormat = new SimpleDateFormat( "MMMMM dd", Locale.US); Date startDate

有人知道为什么KitKat格式会生成本月的第一个字母,而不是本月的第一个字母吗
有解决办法吗
