ok, this isn't my code but its a good starting point:
public View getView(int position, View convertView, ViewGroup parent) {
View vi=convertView;
ViewHolder holder;
if(convertView==null){
vi = inflater.inflate(R.layout.item, null);
holder=new ViewHolder();
holder.text=(TextView)vi.findViewById(R.id.text);;
holder.image=(ImageView)vi.findViewById(R.id.image);
vi.setTag(holder);
}
else
holder=(ViewHolder)vi.getTag();
holder.text.setText("item "+position);
holder.image.setTag(data[position]);
imageLoader.DisplayImage(data[position], activity, holder.image);
return vi;
}
This is what is happening, the method is called everytime a new item
comes into view. For new items 'convertView' will be null, you then
assign a layout to the view and set-up any controls, the vi.SetTag,
passes data to the view that you can use to work out what the item
actually is. In the example above it uses a background class
'imageLoader' to load the images in the background.
Hope this helps.
Regards,
Simon

I am doing something very similar its because the views in
the listview are re-used as you scroll them out of view
they are re-cycled for the new views coming into view.
You need to manage the change over in the getView method.
