Answer 1

Seems like Adapterview does not allow adding new view, I encountered same problem

Solve it by replacing following line

convertView  = inflator.inflate(R.layout.child_rows, parent);

to

convertView  = inflator.inflate(R.layout.child_rows, null);

UPDATE

Instead of not using a parent at all, you should simply tell the Inflater not to attach the inflated view to the parent with

convertView = inflator.inflate(R.layout.child_rows, parent, false); 

See also this answer.

The reason is that adapter takes care of attaching views to parent itself.
