setTraversalBefore
Sets the view before whose node this one should be visited during traversal. A screen-reader must visit the content of this node before the content of the one it precedes.
Note: Cannot be called from an android.accessibilityservice.AccessibilityService. This class is made immutable before being delivered to an AccessibilityService.
Parameters
The view providing the preceding node.

Sets the node before which this one is visited during traversal. A screen-reader must visit the content of this node before the content of the one it precedes. The successor is a virtual descendant of the given root. If virtualDescendantId equals to NO_ID the root is set as the successor.
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: Cannot be called from an android.accessibilityservice.AccessibilityService. This class is made immutable before being delivered to an AccessibilityService.
Parameters
The root of the virtual subtree.
The id of the virtual descendant.
