-EDIT- THIS QUESTION IS NOT A DUPLICATE. The other methods I have tried does not expand my view to make it a scrollable view with new and old content showing.
What should I be looking for or how should implement this layout if I want my screen to expand vertically on a click of a button. That is for instance:
Screen 1 has its own content in it whatever it may be, and on the click of a button the screen layout keeps its content (the button goes away) and extends the layout with additional options making it a scrollable listview.
