Package 

Class BaseCameraScanFragment

  • All Implemented Interfaces:
    android.content.ComponentCallbacks , android.view.View.OnCreateContextMenuListener , androidx.lifecycle.LifecycleOwner , androidx.lifecycle.ViewModelStoreOwner , androidx.savedstate.SavedStateRegistryOwner , com.king.camera.scan.CameraScan.OnScanResultCallback 
    
public abstract class BaseCameraScanFragment<T>
extends Fragment implements CameraScan.OnScanResultCallback<T>

    相机扫描基类；BaseCameraScanFragment 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 BaseCameraScanActivity或者BaseCameraScanFragment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BaseCameraScan。（适用于想在扫描界面写交互逻辑，又因为项目 架构或其它原因，无法直接或间接继承BaseCameraScanActivity或BaseCameraScanFragment时使用）

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

    • Method Summary

      Modifier and Type Method Description
      View onCreateView(@NonNull() LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
      void onViewCreated(@NonNull() View view, @Nullable() Bundle savedInstanceState)
      void initUI() 初始化
      void initCameraScan(@NonNull() CameraScan<T> cameraScan) 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
      void onDestroyView()
      boolean isContentView() 返回true时会自动初始化createRootView，返回为false是需自己去初始化createRootView
      View createRootView(LayoutInflater inflater, ViewGroup container) 创建mRootView
      int getLayoutId() 布局ID；通过覆写此方法可以自定义布局
      int getPreviewViewId() 预览视图previewView的ID
      int getFlashlightId() 获取 ivFlashlight 的ID
      CameraScan<T> getCameraScan() 获取CameraScan
      View getRootView() 获取根视图
      CameraScan<T> createCameraScan(PreviewView previewView) 创建CameraScan
      abstract Analyzer<T> createAnalyzer() 创建分析器
