Remarks
Returns an AccessibilityNodeInfo representing a virtual view, such as a descendant of the host View, with the given virtualViewId or the host View itself if virtualViewId equals to #HOST_VIEW_ID.
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 them selves as a tree of virtual views, thus conveying their logical structure.
The implementer is responsible for obtaining an accessibility node info from the pool of reusable instances and setting the desired properties of the node info before returning it.
