Android: Get number of groups in ExpandableListView?

is there a way to get 开发者_运维问答the number of groups in an ExpandableListView? Or do I have to "remember" how many group items I have added?

You can get the group count through the ExpandableListView's adapter:

ExpandableListView v;
[...]
final int groupCount = v.getExpandableListAdapter().getGroupCount();
