how to get view of group in expandablelistview in android?

im blazilian so, my english is not good.
So.. i need get view of group in expandablelistview for get your object
tag throught view.getTag() method.
follow me in this example:
ExpandableListView
--> group (i need this view)
----> child
----> child
----> child
--> group (i need this view)
----> child
----> child
My code:
@Override
public boolean onChildClick(final ExpandableListView parent, final View v,
final int groupPosition, final int childPosition, final long id) {
/* I NEED GET VIEW OF GROUP FOR GET YOUR TAG*/
View vParent = parent.getChildAt(groupPosition); // dont work
after first group
Programa v2 = (Programa) parent.getTag(); // return null
// v parameter is a child of group
return true;
}
in my adapter:
@Override
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
TwoLineListItem view = (TwoLineListItem) LayoutInflater.from(contexto)
.inflate(android.R.layout.simple_expandable_list_item_2,
parent, false);
String programa = map.keySet().toArray(new
String[map.keySet().size()])[groupPosition];
view.getText1().setText(programa);
view.getText2().setText("PROGRAMA LOCAL");
view.setTag(programas.get(groupPosition)); // i need get this in child
click listener
return convertView = view;
}
any idea? thanks
