Update Custom ListView Item

I have a listview that uses a customadapter based on the baseadapter. The listview populates ok using external data and I can pick up the click events and know which item has been selected.

I'm having a problem updating the clicked item's views, like TextView and ViewFlipper.

Do I have to update something via the listview or is it via the adapter. I've tried things like the following;

View test = (View)adapter.getView(pos, null, myListView);
ViewFlipper temp = (ViewFlipper)test.findViewById(R.id.flipholder);
temp.showNext();
TextView temp2 = (TextView)test.findViewById(R.id.filmtitle);
temp开发者_如何学Go2.setText("Hello World");

Which results in the viewfliper flipping the first and third item or second and fourth and the text not updating at all.

Any ideas?

Cheers

Try this pattern in getView:

public View getView(int position, View convertView, ViewGroup parent) {
        // A ViewHolder keeps references to children views to avoid unneccessary calls
        // to findViewById() on each row.
        ViewHolder holder;

        // When convertView is not null, we can reuse it directly, there is no need
        // to reinflate it. We only inflate a new View when the convertView supplied
        // by ListView is null.
        if (convertView == null) {
            convertView = mInflater.inflate(R.layout.list_item_icon_text, null);

            // Creates a ViewHolder and store references to the two children views
            // we want to bind data to.
            holder = new ViewHolder();
            holder.text = (TextView) convertView.findViewById(R.id.text);
            holder.icon = (ImageView) convertView.findViewById(R.id.icon);

            convertView.setTag(holder);
        } else {
            // Get the ViewHolder back to get fast access to the TextView
            // and the ImageView.
            holder = (ViewHolder) convertView.getTag();
        }

        // Bind the data efficiently with the holder.
        holder.text.setText(DATA[position]);
        holder.icon.setImageBitmap((position & 1) == 1 ? mIcon1 : mIcon2);

        return convertView;
    }

    static class ViewHolder {
        TextView text;
        ImageView icon;
    }
}
