Hi,
I've got a ListView with a custom BaseAdapter. The list items contain CheckBoxes that need to represent a property from a database.
I use CheckBox.setOnCheckedChangeListener with a new OnCheckedChangeListener to detect changes, so I can change the database based on the current state of the CheckBox. Pretty straightforward stuff so far.
However, when scrolling further down the list, previously checked CheckBoxes get unchecked. I suspect this happens as soon as the views are recycled (I'm using the convertView/ViewHolder technique).
How can I stop this? What's going wrong?
Thanks in advance.
Edit: To make things a bit clearer, the problem is that recycling views somehow calls OnCheckedChangeListener#onCheckedChanged(buttonView, isChecked) with isChecked == false.
