For some reason I am not able to figure out how to create the scroll affect for an android app in android studio. I've looked at videos copied the same style asked chatgpt everything and I cant seem to figure out how.

even though the signout block would be out of screen it wont let me scroll.
The negative value of
marginBottominsignout_layoutis the problem. The scroll seems to be working well. But because of setting -144dp as the margin, the scroll view is not only hiding the sign out layout, but also not letting user to scroll. It's because it's thinking that it has already reached the bottom.It would be okay to use negative value for margin bottom if this layout were in the top or in the middle of the screen. However, since it's in the bottom, this problem is occurring.
I'd recommend not to use marginBottom at all because it seems redundant. Even if you do, use a non negative value. And if you want to hide the view, use
android:visibility="gone".Also, your code can be optimised a lot! For example, in some parts, you coded like this:
It can be simplified to the following:
This will not only boost the efficiency of the app, but also make it easy for others to read your code.
