[Android Tips] 21. Regex Named Groups in Android

Android SDK 并没有包含 Java 7 新增加的命名捕获组功能，需要使用第三方库 https://github.com/tony19/named-regexp

import com.google.code.regexp.Pattern;
import com.google.code.regexp.Matcher;

public class NamedRegexpTest {
    public static void main(String[] args) {
        // pattern contains capture group, named "foo"
        Matcher m = Pattern.compile("(?<foo>\w+) world").matcher("hello world!");
        m.find();
        System.out.println(m.group("foo")); // prints "hello"
    }
}
