  • Method Details

    • setSplashScreenResourceId

      public void setSplashScreenResourceId(@LayoutRes int resourceId)
      Sets the resource layout identifier for camera splash screen. If you wish to disable splash screen, set 0. By default, bult-in splash screen (R.layout.mb_camera_splash) will be used. You can also overwrite that layout resource in your app with custom layout.
      Parameters:
      resourceId - Identifier for splash screen layout or 0 to disable splash screen.

    • getSplashScreenResourceId

      @LayoutRes public int getSplashScreenResourceId()
      Returns the currently set resource layout identifier for camera splash screen or 0 if splash screen is disabled.
      Returns:
      currently set resource layout identifier

    • getRecognizerRunnerView

      @Nullable @AnyThread public RecognizerRunnerView getRecognizerRunnerView()
      Returns the RecognizerRunnerView managed by this fragment. If RecognizerRunnerView is still not created, returns null.
      Returns:
      the RecognizerRunnerView managed by this fragment.

    • getContentLayout

      @Nullable public android.widget.FrameLayout getContentLayout()
      Returns the FrameLayout that represents the content layout of this fragment. If content layout is still not created (i.e. before Fragment.onCreateView(LayoutInflater, ViewGroup, Bundle) callback has been invoked, returns null. Note that on ScanningOverlay.onRecognizerRunnerViewCreated(RecognizerRunnerFragment) it is guaranteed that content layout exists and contains exactly one view - RecognizerRunnerView, which can also be obtained with getRecognizerRunnerView().
      Returns:
      content layout of this fragment.

    • setCameraEventsListener

      public void setCameraEventsListener(@Nullable BaseCameraEventsListener cameraEventsListener)
      Sets the camera events listener that will be additionally notified about camera events.
      Parameters:
      cameraEventsListener - camera events listener that will be additionally notified about camera events.

    • registerLifecycleObserver

      public void registerLifecycleObserver(@Nullable LifecycleObserver lifecycleObserver)
      Registers the LifecycleObserver that will be notified about all lifecycle events of this RecognizerRunnerFragment
      Parameters:
      lifecycleObserver -

    • recreateRecognizerRunnerView

      public void recreateRecognizerRunnerView()
      Recreates contained RecognizerRunnerView which causes that ScanningOverlay.onRecognizerRunnerViewCreated(RecognizerRunnerFragment) is called again when new RecognizerRunnerView is created.
