I actually have another question about an understanding of a particular
behavior. I found that whenever I clicked on a CheckBox, while other items
are being added to the list, it seems to move to other items in the list.
Sometimes it would even check off another item's CheckBox at the same time
as I check off something else.
I found a few posts relating to this and it was suggested that I set the
checked status during the getView method, the same time I bind the other
data to it. That makes sense, however when I go to do that I get the same
behavior. I then tried resetting the listener, by setting it to null, based
off someone else's code, before I set the checked status and set the
listener again. And now it works! What I want to know is why? I don't
understand how resetting the listener affects the check status.
public View getView(int position, View convertView, ViewGroup parent)
{
CheckBoxItemView itemView;
// Create a new view if this one is null
if (convertView == null)
{
itemView = new CheckBoxItemView(app_context);
}
else
{
itemView = (CheckBoxItemView) convertView;
}
// Bind the data to the new widget from the data from given list
itemView.setName(device_list.get(position).getName());
itemView.setText(device_list.get(position).getText());
itemView.setIconImage(device_list.get(position).getIconImage());
// Reset the listener for the CheckBox its checked status
itemView.getCheckBox().setOnCheckedChangeListener(null);
itemView.setChecked(device_list.get(position).isChecked());
// Set the listener for the CheckBox
itemView.getCheckBox().setOnCheckedChangeListener(
device_list.get(position));
return itemView;
}
