public class ReviewFragmentStandard extends Fragment implements ReviewFragmentInterface
When you use the Compontent API without the Android Support Library, the ReviewFragmentStandard
displays the photographed or imported image and allows the user to review
it by checking the sharpness, quality and orientation of the image. The user can correct the
orientation by rotating the image.
Include the ReviewFragmentStandard
into your layout by using the ReviewFragmentStandard.createInstance(Document)
factory method to create an instance and display
it using the android.app.FragmentManager
.
A ReviewFragmentListener
instance must be available until the ReviewFragmentStandard
is attached to an activity. Failing to do so will throw an exception. The
listener instance can be provided either implicitly by making the hosting Activity implement the
ReviewFragmentListener
interface or explicitly by setting the listener using ReviewFragmentStandard.setListener(ReviewFragmentListener)
.
Your Activity is automatically set as the listener in ReviewFragmentStandard.onCreate(Bundle)
.

ReviewFragmentInterface
This is important for managing the behavior of the Review Document Fragment when the Next button was clicked.
If the document has already been analyzed and the image wasn't changed when the user
tapped the Next button, ReviewFragmentListener.onDocumentReviewedAndAnalyzed(Document)
is called and there is no need to show an AnalysisActivity
or AnalysisFragmentStandard
or AnalysisFragmentCompat
.
If the document wasn't analyzed or the image was changed when the user tapped the Next
button, ReviewFragmentListener.onProceedToAnalysisScreen(Document)
is called.

ReviewFragmentInterface
By default the hosting Activity is expected to implement the ReviewFragmentListener
. In case that is not feasible you may set the listener using this
method.
Note: the listener is expected to be available until the fragment is attached to an activity. Make sure to set the listener before that.
