Background image in a layout

Flow
1

I need to make a “layout” have a background image, and I can place all my components on top of the background image. When I do it, the image does not allow to see the components. That is, I need the image and the rest of the components to share the same space, the image in the background and the components above.

Any suggestions?

How are you doing it now?

Hello:

I solved it, changing the order of incorporation to the Layout. That is, I put the image first and then the rest of the components.
