I am working on a client-server project in android.I need to parse xml from
url and place it in Expandablelistview. The problem arises when i am trying
to place childs inside each group based on the data coming from server. My
code only places the first child inside first group, but i can't create two
separate groups.
I need to place "payment_method" and "total" inside respective
group(e.g:Groupname:OrderInfo,customerInfo,
Childname(OrderInfo):payment_method,total,
Childname(CustomerInfo):firstname,lastname).My code can placed
Childname(OrderInfo) inside OrderInfo group, but i wish to need when i
click customerInfo group, the firstname,lastname also displayed
customerInfo group.pleasehelp me how is to do. my code is attached
above.please give me some solution for develop this.
Thank You.
