There are several things in this screenshot.
From a fast look: tabhost, some kind of cardview, a floating button (?), edittext with material theme, an add.
This all can be done with b4a and the libraries.
It has reason. I want to make this part of the screen that would be a list with an image on the left and a number on the right. and that when displayed shows a detail of that number. I'll keep looking to see if any bookstore does this. thanks for answering Felix
