Initially expanded group in ExpandableListView

I want my group to be expanded at first time. Then it should behave as usual (collapse/expand after click on indicator)

I cannot found any working solution for this problem.

Loop through all groups and use expandGroup() of your ExpandableListView:

ExpandableListView expView = (ExpandableListView) findViewById(R.id.expView);
ExpandableRecAdapter expAdapter = new ExpandableRecAdapter(this, expHeaders, expItems);
expView.setAdapter(expAdapter); 

for (int i = 0; i < expAdapter.getGroupCount(); i++)
    expView.expandGroup(i);

(or see other StackOverflow questions like this one: ExpandableListview How to Auto groupExpand - Android)
