I'm not sure I understand exactly what you are trying to do... But from the code you posted, it looks like you are wanting to change the view of the last clicked item somehow. This should really be handled by the getView() method of your adapter. You would need to write a custom adapter to do this but that is the correct way to handle something like this.
Here are some high level steps to help you get started: 1. Subclass an adapter class of your choosing (I usually like to use BaseAdapter, but I have also subclassed ArrayAdapter before) 2. Have the adapter keep track of the position of the last clicked item. I would probably do this by having a member variable on the adapter, and a getter and setter to change it. That way, in your onItemClick() method you can set that value on your adapter 3. When you implement getView() on your adapter, check if the current position is the position of the last clicked item and handle it appropriately. 4. If you do this right, you most likely won't have to deal with all of the code to manually resize an item in the list... Hope that helps...
