android making layout scrollable when soft keyboard open, but not shifting it upwards -

this screen, 1 button hidden behind keyboard.

i want this, scrollable. -

whenever, keyboard gets opened, want make same in image. but, instead make scrollable, user can scroll view bottom part of screen (including button), when keyboard open.

i tried -

android:windowsoftinputmode="adjustresize" 

but, shifts bottom part upwards, whenever keyboard opened.

as in image -

i don't want this - (shifting of create account button upwards, when keypad opened)

create account button must visible after scrolling.

here layout -
