@Override public int getViewTypeCount() {

    if (convertView == null) {
            convertView = layoutInflater.inflate(R.layout.layout_row_myappointments, null);
            holder = new ViewHolder();

//your fields like below:

            holder.userName = (TextView) convertView.findViewById(R.id.username);

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

Try to change code like this in your getView()

Answer 3

Have you used ViewHolder to hold view in its position? If not then use it.
