public class CaptureActivity
extends AppCompatActivity implements CameraScan.OnScanResultCallback

    相机扫描基类；CaptureActivity 内部持有CameraScan，便于快速实现扫描识别。

    快速实现扫描识别主要有以下几种方式：

    1、通过继承 CaptureActivity或者CaptureFragment或其子类，可快速实现扫描识别。 （适用于大多数场景，自定义布局时需覆写getLayoutId方法）

    2、在你项目的Activity或者Fragment中实例化一个DefaultCameraScan。（适用于想在扫码界面写交互逻辑，又因为项目 架构或其它原因，无法直接或间接继承CaptureActivity或CaptureFragment时使用）

    3、继承CameraScan自己实现一个，可参照默认实现类DefaultCameraScan，其他步骤同方式2。（高级用法，谨慎使用）

    • Method Summary

      Modifier and Type Method Description
      void initUI() 初始化
      void initCameraScan() 初始化CameraScan
      void startCamera() 启动相机预览
      void onRequestPermissionsResult(int requestCode, @NonNull() Array<String> permissions, @NonNull() Array<int> grantResults)
      void requestCameraPermissionResult(@NonNull() Array<String> permissions, @NonNull() Array<int> grantResults) 请求Camera权限回调结果
      boolean isContentView() 返回true时会自动初始化setContentView，返回为false是需自己去初始化setContentView
      int getLayoutId() 布局ID；通过覆写此方法可以自定义布局
      int getViewfinderViewId() viewfinderView 的 ID
      int getPreviewViewId() 预览界面previewView 的ID；可通过覆写此方法自定义ID
