Bottom button is cut off in my layout, we can't see the whole layout

Question

I am using a relative layout to produce something that looks like image one. But on some phones (see image 2) the bottom button is cut off and we can't see the whole layout. Isn't the purpose of relative layout to adjust itself depending on what phone it is?

What can I do to fix this? If there's no simple way should I just have it scroll down so that we can see the button?

Thanks

Here is my xml layout
