AdjustResize dynamically calculates the size of each view so that it can fit as much of them as possible into the screen when soft keyboard is visible. The whole point of this is that the developer shouldn't have to worry about the resizing of the views and the relative distance between them. The system will automatically resize the views for you so that the user can see as much of the views as possible.
So, unless you are willing to look at the Android source and figure out a way to override the default behavior (maybe there is a way to subclass input method classes), what you are asking for is not possible.
