For Google about BaseAdapter class In Android 1.6 and 2.0 the BaseAdapter class has apparently been modified to throw an exception when it sees the Adapter.getCount() method return a number different than what it picked up when BaseAdapter.notifyDataSetChanged() was called (at least I did not observe this behavior in pre 1.6).
So now the question is, when should one call notifyDataSetChanged() or more importantly, when can the count in the Adapter be safely changed? Consider the case of an app with a background thread delivering data to a BaseAdapter at a rate faster than the ListView responds to notifyDataSetChanged(). Because notifyDataSetChanged() is a synchronous call and the ListView updates are taking place sometime in the indeterminate future on the UI thread, how can an app know when it is safe to change the adapter count? If the app changes the count while the ListView is updating itself the exception will be thrown (and there is no way to catch the exception). Is there a way to know when it is safe to change the count in the BaseAdapter? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
