说明：
最新有二维码扫描需求，就研究了一下二维码扫描：找了很多项目目前觉得这个还是蛮好用的：https://github.com/bingoogolapple/BGAQRCode-Android
这里只是用到了ZXingDemo的代码二维码扫描功能
效果图：
自己的代码：
具体看git的Demo代码，下面是自己写的扫描二维码的代码：
1.gargle引入：
//二维码扫描
compile 'com.google.zxing:core:3.2.1'
compile 'cn.bingoogolapple:bga-qrcodecore:1.1.3@aar'
compile 'cn.bingoogolapple:bga-zxing:1.1.3@aar'
2.扫码类：

6.权限
<!-- 扫码 --> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.VIBRATE" /> <uses-permission android:name="android.permission.FLASHLIGHT" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
遇到的问题：
1.使用gardle导入jar包的时候，
compile 'cn.bingoogolapple:bga-qrcodecore:1.1.3@aar'1.1.3的版本号一定要输入对，否则导入不成功。
2.Demo中没有考虑那么全对于摄像头打开和关闭，这里需要自己打Log来测试一下扫码的顺序，这样好开发。
3.Demo中是按钮启动扫码的，不会打开Activity就会扫码的，所以自己打开Activity的时候要自己启动一下扫码：
mQRCodeView.startSpot();
