本文主要是介绍Android实战简易教程三十六（监听短信-实现短信验证码自动填入），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一般用户喜欢用手机号作为用户名注册APP账号，这时一般都是通过手机验证码的方式进行验证，下面我们就研究一个非常实用的方法，通过监听短信-实现短信验证码的自动填入，提高用户体验。 
首先我们看一下如何监听手机短信。

一、获取短信全部内容

1.新建一个SMSBroadcastReceiver:

<code class="hljs java has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">package</span> com.example.messagecut;

3.创建MainActivity.java-用于接收显示短信信息内容：

5.在真手机上运行项目，然后用另一台手机发送信息，得到如下截图： 
 
截取到了短信内容。

二、截取验证码

上面实现了截取短信全部内容，下面我们看一下如何截取有效信息–验证码。原理应该很简单，就是在字符串中截取部分字符串。 
算法即：

超吊超实用的功能，赶快引入到你的项目中去吧，会大大提高用户体验！

这篇关于Android实战简易教程三十六（监听短信-实现短信验证码自动填入）的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
