Questionnaire
Data item for QuestionnaireItemViewHolder in RecyclerView.
The view should use questionnaireItem, answers, enabledAnswerOptions, validationResult and enabledDisplayItems to render the data item in the UI. The view SHOULD NOT mutate the data using these properties.
The view should use the following answer APIs to update the answer(s):
setAnswer (for single and repeated answers)
clearAnswer (for single and repeated answers)
addAnswer (for repeated answers only)
removeAnswer (for repeated answers only)
Updates to the answers using these APIs will invoke answersChangedCallback to notify the view model that the answer(s) have been changed. This will trigger a re-render of the RecyclerView UI.
Parameters
the ValidationResult of the answer(s) against the questionnaireItem
the callback to notify the view model that the answers have been changed for the QuestionnaireResponse.QuestionnaireResponseItemComponent
the enabled answer options in questionnaireItem
the inclusive lower bound on the range of allowed answer values, that may be used for widgets that check for bounds and change behavior based on the min allowed answer value, e.g the Slider widget
