Unable to make only part of view scrollable

Hi, I’m developing an app which has a button-bar that should be fixed.
However, scrolling in the rest of the view should be enabled.

I only found how to disable scrolling of full content:

Any advice is appreciated.

To enable a section of the view to be scrollable:

<scroll direction="y">
	<item>Item 1</item>
	<item>Item 2</item>
</scroll>
