android - is this the right way to create a custom round corner layout like this?

Question

I want to create a layout like this.layout

The big rectangle will be divided into smaller rectangles (with rounded corners) shown in yellow. I want to place my items like image in the smaller rectangles. I do not know what to search for to get related links. I do not know that is why asking. I think this is a place for experts only.
yellow rectangles are not a problem, but how to create that additional layout inside another layout. Like if I declare a layout inside another layout, it will take the whole space. How to get a border of rounded corners that leaves space at 4 sides.
I was adviced to use shape xml. But I want a layout where I can place child components and not a drawable.

I made a code. I want to know if it is the right way to do?
