Manually Show ExpandableListView

Question

How to show ExpandableListView manually if i touch a button. So far, the only way i can open it is by sliding the screen.

I couldn't find any method like show() like on Toast. I've tried looking for any similar sound method on android reference.

Answer 1

I think you can try scrollTo method to scroll to a postion.
For open/ close a group, you can use expand method.

Answer 2

I found the answer. Turns out, i was wrong. I should've animate the container. In this case, the drawer.

I got my answer from here. How to open Drawer Layout only with button?

I just need to call opendrawer().
