Auto scrolling in ExpandableListView


I would like my ExpandableListView to automatically scroll when the user expands a group, so that the expanded group header is at the top of the screen. I've tried smoothScrollToPosition, but this merely ensures the expanded group is visible somewhere on the screen. I would like to explicitly scroll it so the expanded group is at the top, like in this example:

Before expanding Group 3:                After expanding Group 3:

+=================+                      +=================+
| Group 1         |                      | Group 3         |
+-----------------+                      +-----------------+
| Group 2         |                      |   Grp 3 Child 1 |
+-----------------+                      +-----------------+
| Group 3         |                      |   Grp 3 Child 2 |
+-----------------+                      +-----------------+
| Group 4         |                      | Group 4         |
+=================+                      +=================+

Solution

  • ListView.setSelection(position)
    

    this will scroll to the selected item, call this when u click on the group item.
