I thought the views get recycled? Isn't that what the convertView argument is in the ListAdapter? @pararm convertView The old view to reuse, if possible. Note: You should check that this view is non-null and of an appropriate type before using. If it is not possible to convert this view to display the correct data, this method can create a new view. Heterogeneous lists can specify their number of view types, so that this View is always of the right type (see getViewTypeCount() and getItemViewType(int)). Our app does not perform too badly redrawing the entire ListView once per second. Certainly slower than the iPhone, but not slow enough to warrant optimizations that in our case would be too difficult to track (i.e. we'd have to iterate through all of the active trading markets to see how they compared with the list a second prior. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
