[android-developers] Re: ListView with custom view item refresh issue

Sure sounds like a bug in getView.  Make sure getView works when position==5 and position==6.

Hi all,

I need your help to understand the refresh behaviour of a ListView where I've defined a my custom view for the ListView's items.

I think It's better explain it with an example:

my adapter contains 7 items: A, B, C, D, E, F, G correctly initialized, filled and working. The associated ListView shows 5 (out of 7) items: A, B, C, D, E.

The problem is that, when I scroll down the ListView's content instead of showing me items F and G, I've got A and B items again. I understood that this is "only" a viewing issue becouse the model elements associated with the last two items, correctly belong to F and G items. :|

Following the ovveride of getView(...) method of my adapter (extending BaseAdapter):

@Override

    public View getView(int position, View convertView, ViewGroup parent) {

        MyItemView miv = (( MyItemView  ) convertView);

        if (context == null) return null;

        if (convertView == null) {

            miv = new MyItemView (........);

            .....

        } else {

            miv.refreshView(); //refresh the view content

        }

        return miv;

    }

and the refreshView() method of MyItemView (extending LinearLayout):

@Override

    public void refreshView() {

        label1.setText(......);

        label2.setText(......);

        label2.setText(......);

        invalidate();

    }

Thanks a lot to all!

Bye

Sergio
