Can you help me identify why there is a space between the group and the child? In my case I want spaces between all groups and the child should be right below the group with no

Answer 1

Modify the view's padding in the method public View getChildView() using the setPadding() method of the view.

Example:

@Override
public View getChildView(int groupPosition, int childPosition, boolean isLastChild,
                             View convertView, ViewGroup parentView){
 final Departure departure = departures.get(groupPosition);

 if(isLastChild)
  expListView.setDividerHeight(DIVIDER_HEIGHT);

 // Inflate childrow.xml file for child rows
 convertView = inflater.inflate(R.layout.view_departure_details, parentView, false);

 //Data handling...

 convertView.setPadding(0, 0, 0, 0);

 return convertView;
}

In the same way, if you want modify padding of the group, you will have to modify the padding in the getGroupView() method.
