Please explain how to make such a screen?

Question

Android

Hello.
Can you please tell me how to make such a screen?

spoiler

The screen consists of two areas - the upper one (gray) is a text description of the product, and the lower one (green) should be an image that is swiped to the side (that is, there is a set of images that are flipped through with a swipe), while over this image (area with an image) there should be a button.
Two questions:
1) Do I understand correctly that it is necessary to divide the screen into two similar areas by placing two fragments in it (the gray part and the green part) or can it be done with one screen?
2) How to lay out the green part? I would be very grateful if someone explains in more or less detail, because there is absolutely no experience in this. What component or library should be used to create swipe images and how should the button be placed on top of this area (via frame layout I guess, but not sure)?
Thanks

Answer 1

1. To divide the fragments in this way is not needed.
The basis of the counterlayout.
Green is nailed to the bottom.
As a gray scroll whose bottom is aligned to the green top.
If the product does not have galleries. Green is on the run.
2. Screw the layout of the found gallery of pictures with a swap.
