Dynamically hiding Views in Custom Listview in Android

I have a custom listview in which I have a Textview and Imageview now I want to hide or display the Imageview for some Items in the Listview ony.

I have done this using getview method but the problem is that when the Listview is displayed at first time the View does not get hide but when I scroll down and scroll up that time it gets hidden. following is the code snippet. Thanks in advance.

 public View getView(int position, View convertView, ViewGroup parent) {
        View v = super.getView(position, convertView, parent);
        ViewHolder holder;
        if (v != convertView && v != null) {
             holder = new ViewHolder();            
             convertView = mInflater.inflate(R.layout.jazzartist, null);
             holder.albumsView = (TextView)convertView.findViewById(R.id.artist_albums_textview);
             v.setTag(holder);


          }
        else{     
       holder = (ViewHolder) convertView.getTag();     }        

        ViewHolder holder1 = (ViewHolder) v.getTag();
        holder1.objimg =  (ImageView)convertView.findViewById(R.id.drag); 
        if(position == 4){  

            (holder1.objimg).setVisibility(View.INVISIBLE); // here I am hiding Imageview for position 4

            } 
        else
        {

            (holder1.objimg).setVisibility(View.VISIBLE); // here I am showing Imageview for rest of items
        }
                 String albums = getItem(position).albums;

        holder1.albumsView.setText(albums);

        return v;
      }
    }

    }

Please remove the conditions i.e if else (don't put check for convertView) 

public View getView(int position, View convertView, ViewGroup parent) {

    ViewHolder holder;
           holder = new ViewHolder();            
         convertView = mInflater.inflate(R.layout.jazzartist, null);
         holder.albumsView = (TextView)convertView.findViewById(R.id.artist_albums_textview);


    holder1.objimg =  (ImageView)convertView.findViewById(R.id.drag); 
    if(position == 4){  

        (holder1.objimg).setVisibility(View.INVISIBLE); // here I am hiding Imageview for position 4

        } 
    else
    {

        (holder1.objimg).setVisibility(View.VISIBLE); // here I am showing Imageview for rest of items
    }
             String albums = getItem(position).albums;

    holder1.albumsView.setText(albums);

    return convertView;
  }
