问题
I'm working on fixing a bug in someone's code and I can't figure out how to get this to scroll correctly. I'm just trying to get the "question" area to scroll vertically. Currently it just grows and pushes everything down. Please help!

回答1:
That is because you set the height of the ScrollView to wrap_content. Try giving it a fixed height or using a LinearLayout with weight so it fills the space left over from the other views.
回答2:
If you do not want to set it to a specific height, you can also add
android:fillViewport="true"
to your ScrollView
回答3:
Your scroll view doesn't have any problem. But, You can not see your scroll bar because your textview has too short text.
Update your code like below.
Scroll bar will be shown up when contents are long than yours automatically.
Good luck, Josh!
