Just to clarify 2: I meant calling super.getView from your adapter's getView, assuming it's a subclass of ArrayAdapter.
Do not call adapter.getView from outside the adapter's code, that's meaningless. Now the view ids.... What layout id do you use to initialize the adapter? Perhaps android.R.layout.<something>? A side note: my suggestions here are just to patch up things based on the route you've already headed down (using ArrayAdapter). One day, as your knowledge grows, you'll want to throw away the three-wheeled bicycle (ArrayAdapter) and create your own, perhaps by extending BaseAdapter. -- Kostya 5 января 2012 г. 20:47 пользователь John Davis <[email protected]> написал: > Hello Kostya, > > Thanks for the reply. > > On Thu, Jan 5, 2012 at 11:39 AM, Kostya Vasilyev <[email protected]> > wrote: > > > > 2: > > > > Yes, you're supposed to call the base class in your case, the > ArrayAdapter > > will be doing most of the work for you, inflating new or reusing existing > > row layouts. > > Ok.
