Apps FrameLayout: 2D-weight Simulation

[Fabiow]

I have a image of a specific graph as a background of a FrameLayout. The FrameLayout has a few views in it representing the (animated) nodes of the background graph. I can get that using a fixed-position strategy, but the problem arises when I go to a different device, since I'm not using a relative position strategy.

I need the (animated) nodes to match the background graph nodes, something like layout_wight in a LinearLayout, but in two dimensions.

Does anyone know how to do it?

Thanks in advance!
