Android replace with regex
提问by raydowe
I have a string in Android. I would like to wrap all the instances of 4 or more continuous digits with some html. I imagine this will be done with regex, but I have a hard time getting even the most basic regular expressions to work.

This will do it:
这将做到：
String input = "My phone is 1234567890 and my office is 7894561230";
String regex = "\d{4,}";
String output = input.replaceAll(regex, "<u>##代码##</u>");
System.out.println(output);
