ListAdapter ruft getView unötig oft auf

1public View getView(int position, View convertView, ViewGroup parent) {
2 testGetView.put(position, convertView); // nur zum Test
3 System.out.println("getView " + position + " " + convertView); // nur zum Test
4 ViewHolder holder = null;
5 if (convertView == null) {
6 convertView = mInflater.inflate(R.layout.category_item, null);
7 holder = new ViewHolder();
8 holder.textView = (TextView)convertView.findViewById(R.id.category_text);
9 holder.textView.setId(position);
10 convertView.setTag(holder);

13 else
14 {
15 holder = (ViewHolder)convertView.getTag();
16 }

18 holder.textView.setText(categories.get(position).getName());
