在Android上没有与“A minute ago”或“An hour ago”之类的字符串获得时差。我之前已经问过这个问题。
How to get "Time Difference" in "since/ago"? Is this possible without use of any library?
这里我从Json Parsing获得时间字符串。格式为YYYY-MM-DD，SS：MM：HH）。 Pic附加

我想知道是否有可能从字母“A minute ago”或“An Hour ago”中获取时间差异。或者我们还需要在PHP Server中做一些更改吗？

使用DateUtils.getRelativeTimeSpanString(Context context, long millis);
将日期的字符串表示形式转换为日期对象
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd ss:mm:HH");
Date d = dateFormat.parse(yourdate)
return DateUtils.getRelativeTimeSpanString(getContext(), d.getTime());
