root
View

The root of the virtual subtree.

virtualDescendantId
Int32

The id of the virtual child.

Attributes
RegisterAttribute

Remarks

Adds a virtual child which is a descendant of the given root. If virtualDescendantId is View#NO_ID the root is added as a child.

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. Note that a view cannot be made its own child.
