Apps problem with choosing a listview item and updating it

[guigo170]

Hello I am trying to work with the setTag view method to detect what items is pressed. my layout is composed of a list each row containing a textfield a togglebutton and an imageview. I would like to change the image of the row containing the pressed button but i have no method to change the image of a specific imageview object depending on its tag. I have gone this far and i'm stuck on how to continue can i get some help please?

setListAdapter(new MyAdapter(this, android.R.layout.simple_list_item_1,
R.id.textView1,
(String[]) myArr.toArray(new String[]{})));
}

class MyAdapter extends ArrayAdapter<String>{

private int which;

public MyAdapter(Context context, int resource,
int textViewResourceId, String[] string) {
super(context, resource, textViewResourceId, string);
// TODO Auto-generated constructor stub
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row = inflater.inflate(R.layout.custom_view, parent,false);
final TextView tv = (TextView) row.findViewById(R.id.textView1);
final ImageView iv = (ImageView) row.findViewById(R.id.imageView1);
final ToggleButton tb = (ToggleButton) row.findViewById(R.id.toggleButton1);
