How is the design "stretched" on applications for ios and android?

Question

Design

For example, I drew the design of all application screens. How do programmers "pull" the design onto the finished functionality in the future?

Answer 1

I hope "for example" does not equal "already painted", because then a number of problems are possible.
android:
in short, I cut it, throw everything I need into folders, with the help of I implement the interface in layout files, transferring colors and sizes to resources along the way. Mother of the designer for the names of the layers in the spirit of layer1, layer2 for the lack of logic in the division into layers, for the sizes taken from the ceiling, and so on ... the designers are different, but there are a lot of similar jambs and often the same. I am not writing to offend, just a cry from the heart ─ there are very few good mobile application designers, and not only I feel their shortage.
