You have to do this through your BaseAdapter. Make sure that your BaseAdapter's individual elements/items have a variable that can determine if one is checked or not.
If you want to check-mark all your list-item item's, run through every element in your BaseAdapter. Set every element to 'isChecked' (or call whatever variable/method is available on your element's class to make it checked). Then call the BaseAdapter's 'notifyDataSetChanged()'. This will cause your BaseAdapter's method 'getView(....)' to be called for all (visible) list-items: Using the 'position' (paramater of 'getView'), get the BaseAdapter's element on that position. Then query that element: if it is checked, check the list-view- item's checkbox. If not, clear this checkbox.
