Layer model with UI components

[paulorrfilho]

I am trying to render a model in a fragment and layer it between two UI components (z position). Somehow Filament does not respect the expected layering provided in the activity layout file.
I tried using the isMediaOverlay attribute in UIHelper but I think it is rendering the model behind my main activity. I also tried changing the elevation in the layout file but it had no impact.
Does Filament support what I am trying to do?

Filament has nothing to do with this. A SurfaceView puts its Surface either below the Activity (by default) or above with isMediaOverlay. You cannot sandwich a SurfaceView between two UI components. To achieve this you need to use a TextureView but it's a little less efficient.

Thanks @romainguy , is this true even if the UI components are in a separate fragments? The Surface view will override any layering I provide?

This has nothing to do with fragments. Think of a SurfaceView as a separate window.
