安卓 —— 图灵机器人+讯飞语音设计实现
版权声明：本文为博主原创文章，未经博主允许不得转载。 https://cloud.tencent.com/developer/article/1333587
前言：
本文主要介绍一下之前学习的安卓平台下 “图灵机器人的设计”，希望能给爱学习的你到来更多的启发和兴趣。当然，随着时间的推延，技术的优化和进步，难免出现新技术的更迭，所以要经常充电学习...
安卓开发：android4.2-5.0
【注：2017-12-12】
今天在同事手机上安装了一下试试，发现红米手机可支持，并且没有使用讯飞输入法也可以完成。
毕竟代码编辑久远，当初的代码是在 android4.2 - 5.0 版本下开发的，如今的安卓版本更新换代快，终究会出现兼容问题，此外两年多没有碰安卓代码了，可能很难给以参考的伙伴以有价值的建议，希望多多进步咯 ...
一.前期准备：
1.代码编写之前，在此提供 前辈大牛的视频讲解 ，其中涉及到了图灵账号的注册和效果实现
2.其中注册网址为 图灵机器人官网 ，具体操作可看官方文档和之前的视频链接
3.在此补充一个感觉很好的 参考博文 ，编写之前也参考了他的很多，主要还是学习众家所长嘛
4.代码使用了讯飞语音，个人认为如果使用的讯飞输入法，同时下载了其语音，在编辑的同时即可使用，而此代码表示需要在联网状态进行语音的输入转化。
二.代码编写：
①. 权限设置
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<!-- 讯飞语音权限开始 -->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<!-- 讯飞语音权限结束 -->②. 项目展开状况如下所示
注意对应的jar包使用，之后会附上源码下载地址作为参考
③. 布局文件
