Android常用的正则表达式

1. 判断手机号是否有效

public static boolean isMobileNO(String mobiles) {

        Pattern pattern = Pattern.compile("^1[3|4|5|7|8]\d{9}$");
        return !TextUtils.isEmpty(mobiles) && pattern.matcher(mobiles).matches() && mobiles.length() == 11;
    }

2.判断邮箱是否合法

public static boolean isEmail(String email) {

        Pattern pattern = Pattern.compile("\w+(\.\w)*@\w+(\.\w{2,3}){1,3}");
        return !TextUtils.isEmpty(email) && pattern.matcher(email).matches();
    }
