  @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;

        if (convertView == null) {
            // brand new
            convertView = LayoutInflater.from(mContext).inflate(R.layout.film_list_item, null);
            holder = new ViewHolder();

            holder.nameLabel= (TextView) convertView.findViewById(R.id.nameLabel);
            holder.emailLabel= (TextView) convertView.findViewById(R.id.emailLabel);
            holder.genderLabel= (TextView) convertView.findViewById(R.id.genderLabel);
            holder.addressLabel= (TextView) convertView.findViewById(R.id.addressLabel);
            holder.imageId= (ImageView) convertView.findViewById(R.id.imageId);


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

        Film day = mFilmler[position];

        byte[] decodedString = Base64.decode(String.valueOf(holder.imageId), Base64.URL_SAFE);
        Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);


        holder.nameLabel.setText(day.getName());
        holder.emailLabel.setText(day.getEmail());
        holder.genderLabel.setText(day.getGender());
        holder.addressLabel.setText(day.getAddress());
        holder.imageId.setImageURI(Uri.parse(day.getImage()));


        return convertView;
    }

    private static class ViewHolder {
        TextView nameLabel; // public by default
        TextView emailLabel;
        TextView genderLabel;
        TextView addressLabel;
        ImageView imageId;
    }

how i can set this image url as an image in my listview ?
