I continued reworking my first simple Android Studio app and I’m happy with the progress I made! I was able to finish the XML layouts for the different modes (day and night). The only changes I’ll have to make when I continue are fixing an issue with contrast for one of the images I used as well as the functionality of the switch that will “transform” the app screen from day to night.

Helpful resources for me were Adobe in a Minute’s “Android Studio: How to Add a Background Image to Activity” and the Stack Overflow post “xml – Z-index in android?“.
