Good day,
I have read your project and I would love to help you. As you can see, it requires support in the visual part of your app, that is, in front-end. I have an experience of 2 years working with XML tag language and I am Android Developer, which can guarantee you that you will get the expected results.
I have downloaded the attached image and seen the scrolling bar that it requires (the one that contains the icons), if you like, and with all freedom, you can contact me and we talk in more detail about what you want from your app.
Regards
Samuel K. Hernández
