Just to answer my own question in case anyone has the same problem.
getCount has to return total number of cells to display in GridView.
So if you want to have 3x3 grid getCount needs to return 9
position in getView is linear e.g. position 7 means row 3 cell 1
convertView is a total mystery as it seems to return random views in
consecutive calls - I ignore it for now and just create new views
every time.
