Question

我想在android中创建包含以下内容的密码模式

大写字符
小写字符
特殊字符
数
，最少8位数。

我使用了 html5 密码模式

String password_pattern = "(?=^.{8,}$)((?=.*\\d)|(?=.*\\W+))(?![.\\n])(?=.*[A-Z])(?=.*[a-z]).*$";

但它不起作用。

Answer 1

尝试使用以下Regex，它可以满足您的需求，

1。大写字母

2。降低信件

3。特殊字符

4. 号码

5。最低8位

^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{8,}$

Answer 2

你可以使用它。

Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?

模式描述

private static final String PASSWORD_PATTERN = "((?=.*\\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%]).{6,20})";

你可以这样使用

  (?=.*\d)      #   must contains one digit from 0-9
  (?=.*[a-z])   #   must contains one lowercase characters
  (?=.*[A-Z])   #   must contains one uppercase characters
  (?=.*[@#$%])   #   must contains one special symbols in the list "@#$%"
              . #   match anything with previous condition checking
  {6,20}        #   length at least 6 characters and maximum of 20
