<strong>Note:</strong> If this view hierarchy has a SurfaceView embedding another view hierarchy via SurfaceView#setChildSurfacePackage, there is a limitation that this API won't be able to find the node for the view in the specified direction on the embedded view hierarchy. It's because views don't know about the embedded hierarchies. Instead, you could traverse all the children to find the node.
