Help identify the layout used here?

Question

I'm working on a layout that comprises some of the same features seen in the screenshot below, but I'm running into a bit of confusion. Can someone help me understand a few points for the screenshot below?

• What is the root layout used here?
• How do I get the button bar to remain at the bottom, while the center section scrolls when it is long enough?
• Similar to the Ok/Cancel buttons seen here, how do I make them each 50% width (minus some margin and padding)?

Answer 1

starting with last one i.e.

Buttons each with 50% width:

• Place both buttons in another linear layout
• Make linear layout's orientation="horizontal"
• make layout's width = "fill parent"
• make button's width = "0px"
• for each button, set layout_weight="1.0"

What is the root layout used here?

• Use a linear layout with orientation="vertical"

• plave a layout for button bar portion with height="wrap_content"

• then a listView

• thne the linear layout for button, described above

section scrolls when it is long enough?

• Use a Custom ListView

• Make height pf listView = "wrap_content"

• Make layout_weight = "1.0" for ListView

i hope it will help if not completely then will give you an idea.
