Android接受验证码自动填入功能(源码+已实现+可用+版本兼容)

实际应用开发中,会经常用到短信验证的功能,这个时候如果再让用户就查看短信.然后再回到界面进行短信的填写,难免有多少有些不方便,作为开发者.本着用户至上的原则我们也应该来实现验证码的自动填写功能，还有一个重要的原因是为了防止恶意注册。今天实现这个功能的方法是用的广播来实现的

首先在AndroidMainfest.xml中加入所需要的权限：

<!-- 短信验证登陆功能需要添加次权限来自动填充验证码，用不到可以去掉 -->
    <uses-permission android:name="android.permission.RECEIVE_SMS" />
    <uses-permission android:name="android.permission.READ_SMS" />

首先看一下实现的效果，没效果说再多都没用，亲眼看到的才知道适不适合自己

中效果看完接下来就看怎么实现的了，这里使用的广播为动态注册，因为这个APP在进程杀死之后就不需要监听这个广播了，在Activity的onDestory之后注销广播。
