I'm new to Android layout design. My problem is that when trying to add a ScrollView to my layout it disappears the rest of my UI. In the following code, when I uncomment the ScrollView, it happens the aforementioned problem.

How can I add properly a ScrollView to my UI? I also feel like I could make my code much better, so I'm open to any suggestion related to it.
Note: I have omitted ids and hardcoded strings rather than using @string resource here.
