- root
- The root of the virtual subtree.
- virtualDescendantId
- The id of the virtual descendant.
Sets the source to be a virtual descendant of the given root. If virtualDescendantId is Android.Views.View.NoId the root is set as the source.
A virtual descendant is an imaginary View that is reported as a part of the view hierarchy for accessibility purposes. This enables custom views that draw complex content to report themselves as a tree of virtual views, thus conveying their logical structure.
Note: Cannot be called from an Android.AccessibilityServices.AccessibilityService. This class is made immutable before being delivered to an AccessibilityService.
