Android开源-Zbar扫描(代码比zxing简单N倍，扫描速度也够快是zxing的3~5倍)

   <p>我找AndroidZbar的代码找了好久，兄弟们有福了，这是github上的一个基于Zbar的开源库 BGAQRCode (这个库真的很棒)。</p>    <h3><strong>代码结构：</strong></h3>    <p style="text-align:center"><img src="https://simg.open-open.com/show/c62a2e0effcae4914aeb4e83b42bc515.png"></p>    <p style="text-align:center">Paste_Image.png</p>    <p>你可以先运行，看下得到的app，反正我没用过zbar，但是看完demoApp就会改代码了，你把它镶嵌入自己的app最多2小时</p>    <h2><strong>主要用到的东西：</strong></h2>    <h3><strong>MainActivity.java</strong></h3>    <p>其实就是跳转界面</p>    <h3><strong>TestScanActivity</strong></h3>    <pre>  <code class="language-java">public class TestScanActivity extends AppCompatActivity implements QRCodeView.Delegate {      private static final String TAG = TestScanActivity.class.getSimpleName();
