User can open multiple collapse section at a time. I have to create this but I am not sure how I can do that, any hint or help will be highly appreciated.

Answer 1

It's called ExpandableListView

A view that shows items in a vertically scrolling two-level list. This differs from the ListView by allowing two levels: groups which can individually be expanded to show its children. The items come from the ExpandableListAdapter associated with this view.
