zxing的github地址为：[https://github.com/zxing/zxing](https://github.com/zxing/zxing)
因为使用过程需要编译（或者拷贝源文件），稍微麻烦一些，所以采用了另外一个封装版本：[https://github.com/yipianfengye/android-zxingLibrary](https://github.com/yipianfengye/android-zxingLibrary)

#### 回调

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
//处理扫描结果（在界面上显示）
if (null != data) {
Bundle bundle = data.getExtras();
if (bundle == null) {
return;
}
if (bundle.getInt(CodeUtils.RESULT_TYPE) == CodeUtils.RESULT_SUCCESS) {
String result = bundle.getString(CodeUtils.RESULT_STRING);
Toast.makeText(this, "解析结果:" + result, Toast.LENGTH_LONG).show();
} else if (bundle.getInt(CodeUtils.RESULT_TYPE) == CodeUtils.RESULT_FAILED) {
Toast.makeText(MainActivity.this, "解析二维码失败", Toast.LENGTH_LONG).show();
}
}
}
}
