android 高兼容性的自动填充验证码工具类（四步代码搞定）

来源：互联网发布：所以语音软件编辑：程序博客网时间：2024/05/16 08:22

验证码自动填充对于移动开发来说是很实用并常见的事。在4.4以前实现验证码填充可以用广播监听，获取验证码。那么4.4以后我们怎么办呢？方法还是有点，或许你以前就是用这种方法来实现的。这是一个工具类，没啥难到的，不多说。对本工具类中提到不懂的类或者字段请自行百度或Bing或Google。

本工具类使用很简单三行代码搞定一个验证码自动填充。

1、在onCreate()中实例化SmsValidateCodeUtils 类，如

mSmsValidateCodeUtils = new SmsValidateCodeUtils(this);
mSmsValidateCodeUtils.register().setOnValidateCodeListener(this).setmValidateName(getResources().getString(R.string.SmsValidateCode));

2、重写接口方法

public void resultValidateCode（String code）{
// TODO

}

3、在onDestroy()中注销 mSmsValidateCodeUtils.unregister();

4、在AndroidManifest.xml中加上这个权限<uses-permission android:name="android.permission.READ_SMS"/>

是不是很简单啊！该类还可以优化，代码不是很规范。这是一个BUG我正在努力调试中……
