   private ArrayList itemChecked = new ArrayList(); // array list for store state of each checkbox

   public VocabCursorAdapter(Context context, Cursor c, int flags) {

       for (int i = 0; i < c.getCount(); i++) { // c.getCount() return total number of your Cursor
            itemChecked.add(i, false); // initializes all items value with false
       }
   }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {

        ...
        final int position = cursor.getPosition(); // get position by cursor

        CheckBox checkBox = (CheckBox) view.findViewById(R.id.editCheckbox);
        checkBox.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {

                    if (itemChecked.get(position) == true) { // if current checkbox is checked, when you click -> change it to false
                        itemChecked.set(position, false);
                    } else {
                        itemChecked.set(position, true);
                    }
                }
       });

       checkBox.setChecked(itemChecked.get(position)); // set the checkbox state base on arraylist object state
       Log.i("In VocabCursorAdapter","position: "+position+" - checkbox state: "+itemChecked.get(position));
    }
}
