I'm able to set the header properly. Dont know how to insert the subitems in each header.

Answer 1

By creating custom adapter view and passing header array and and subitems array seperately in adapter parameters. I ended up with this logic and it works fine. Created seperate header view_holder and subitems viewholder with seperate xml views. The logic will be helpful for others. If any doubts comment here.
