Android ListView with Checkbox: automatically unchecks?
Apparently the problem was that, by getting the checkbox using convertView.findViewById(), the onCheckedChangeListeners were still intact if the view was recycled. Calling checkbox. SetOnCheckedChangeListener(null) did the trick.
1 I was having the same problem when using checkbox in the child view of an ExpandableListView, and your trick worked for me as well. I had to put this in getChildView(..), where I check if we are recycling (i.e. , convertView is not null), and set the OnCheckedChangeListener of the checkbox to null in that case.
Thanks for the solution. – Samik R Aug 19 '10 at 5:33 I am having a similar problem, but I don't know how to fix it: stackoverflow. Com/questions/4586442/… any ideas?
– ekawas Jan 5 at 15:24 I know its an old thread but I have the same problem. It seems like the onCheckedChangeListener method is called randomly. What exactly do you mean by checkbox.
SetOnCheckedChangeListener(null)? Its the null that confuses me! Have a look at my code if you want: stackoverflow.Com/questions/5444355/… – mixkat Mar 27 at 3:05.
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?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
