Thanks!
It works!
But, my tile layer data contains Web Mercator (3857) and WGS-84 (4326) , with the constraint by SceneViewTilingScheme, they can not be visible at the same time.
Suggestion: SceneViewTilingScheme maybe set to tile layer, and SceneView can display both Web Mercator (3857) and WGS-84 (4326) tiles.
