Perfect solution for expanding expandable listview

ExpandableListAdapter expandableListAdapter;
ExpandableListView expandableListView;

expandableListView.expandGroup(0);
expandableListView.expandGroup(1);

expandableListAdapter.notifyDataSetChanged();

This is a perfect solution, it will increase automatically

ExpandableListView elv = (ExpandableListView) findViewById(R.id.elv_main);
elv.setAdapter(adapter);
for(int i=0; i < adapter.getGroupCount(); i++)
    elv.expandGroup(i);

but this is based on the item positions

ExpandableListView Exlist;
Exlist.expandGroup(0);// first item of listview
Exlist.expandGroup(1);//second item of listview

I built this snippet based off Nikhil's answer. Thought others might find it useful as well. Only works if you are using BaseExpandableListAdapter. elv

ExpandableListView elv = (ExpandableListView) findViewById(R.id.elv_main);
elv.setAdapter(adapter);
for(int i=0; i < adapter.getGroupCount(); i++)
    elv.expandGroup(i);
