I have edited the source code to display all scale information (BodyFat%, Hydration, etc) however the vast majority of this needs a user profile to be calculated properly. I am looking for a way to add text input to the GUI, so essentially the user enter their own age, height, etc and this will be added to the user profile page. I'm still fairly new to developing for android, is it possibly to simply add these fields to the existing GUI or will I have build an entirely new one? Thank you.
