You could use substring like so
你可以像这样使用子字符串
String date = yourString.substring(0, 10);
This would pull all the characters from 0 to 10 in your String and save it as a new String.
这会将字符串中的所有字符从 0 拉到 10 并将其保存为新字符串。
In this case that would return "2017-04-26"
在这种情况下，将返回“2017-04-26”

In my opinion the cleanest way to do it :
在我看来，最干净的方法是：
- extract the date as described here : Java string to date conversion
- create a string containing the formatted date you want thanks to another DateFormat
- display it!
- 按照此处所述提取日期：Java string to date conversion
- 由于另一个 DateFormat，创建一个包含您想要的格式化日期的字符串
- 显示它！

You can always use Java's DateFormatAPI for achieving this. Here is the code snippet that will help you to achieve whatever task you are looking for.
您始终可以使用 Java 的DateFormatAPI 来实现这一点。以下代码片段将帮助您完成您正在寻找的任何任务。
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSXXX");
Date date = dateFormat.parse("2017-04-26T20:55:00.000Z");//You will get date object relative to server/client timezone wherever it is parsed
DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd"); //If you need time just put specific format for time like 'HH:mm:ss'
String dateStr = formatter.format(date);
You will get date object from which you can use it whichever way you would like to display using date formatter to format again.
您将获得日期对象，您可以从中以任何方式使用它，使用日期格式化程序再次格式化。
