Use this I think this will work on every screen.
Since your size is fix so in small phone your UI will be cut but i use the phone width which make UI more flexible to use in approximately in every screen :)

You could consider using ConstraintLayout instead to make your layouts responsive

Adjust layout perfectly on all screens

Hi i have this screen for my app but instead of scrollview i want layout to fit perfectly for every screen size phones. Like i want every layouts to decrease height accordingly if the phone screen height is small.
There is margin in the bottom, i don't want that extra space.

When activity is loaded, scrollview starts in middle and not top. Is there a way to fix it?

I have a very long scrollview. When the activity is loaded, the scrollview starts in the middle and not the top (and you have to scroll up to see the first items in the scroll view). Can't figure this one out, never had this happen before. Is there a way of fixing it? Here's my resource file:

I tried adding
android:descendantFocusability="beforeDescendants"
android:focusableInTouchMode="true"
to the scroll view properties because I have read elsewhere on StackOverflow that this is how it's fixed, but it does not actually fix it.
