You should set CheckedBox state outside the initialization of ViewHolder, like the following code:

if (convertView == null) {
    viewHolder = new ViewHolder();
    convertView.setTag(viewHolder);
} else {
    viewHolder = (ViewHolder) convertView.getTag();
}

viewHolder.checkedBox.setChecked();

BTW: use SparseBooleanArray instead of two list to store CheckedBox state.
