Scrollview not scrolling the entire screen

Question

Currently, my scrollview could only scroll the bottom part of the screen. However though, I want the scrollview to be able to scroll the entire screen like how you would be able to normally and smoothly scroll an entire screen within an app. But i can't figure out what went wrong where for me as only i could scroll the bottom portion of the screen.Could anyone advise me on how? Thanks

Answer 1

I think your layout is too unnecessary complicated. The highest RelativeLayout does nothing here. Make ScrollView your root view and set it's width and height to match parent.

Answer 2

Try it:

<androidx.core.widget.NestedScrollView
    android:layout_width="wrap_content"
    android:layout_height="match_parent">

...

</androidx.core.widget.NestedScrollView>

Also You can try to set "android:layout_height="match_parent">" for ScrollView and set "android:layout_height="wrap_content">" for its child layout.
