I figured this out also. Chalk it up to me being a total rookie with
gui programming. The issue is that the list items get reused and I
was calling setChecked from within my bindView code *before* setting
the OnCheckedChangeListener. During startup it doesn't really matter
because the list items are all being created for the first time and
there are no registered listeners. However on subsequent rebindings,
the old listener is still associated with the view and when I call
setChecked... all hell breaks loose. So the key was simply to set the
callback before calling setChecked. Also I was calling setChecked
within the callback and calling notifyDataSetChanged which were just
causing more iterations through this loop and more craziness. Anyway,
here is the working code:
// We need to be sure and register the new
OnCheckedChangeListener
before
// we call setChecked because these views get reused
and there
might still
// be old callbacks associated with previous alarm
"item"s which
causes very
// f-ed up behavior. (I know)
CheckBox enabledCheckBox =
(CheckBox)alarmView.findViewById
(R.id.itemEnabledCheckBox);
enabledCheckBox.setOnCheckedChangeListener(new
OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton
buttonView, boolean
isChecked) {
item.setEnabled(isChecked);
dbAdapter.updateAlarm(item.getId(),
item);
}
});
enabledCheckBox.setChecked(enabled);
