    imageView = (ImageView) list.findViewById(R.id.pic1);
    textView1 = (TextView) list.findViewById(R.id.det2);
    textView2 = (TextView) list.findViewById(R.id.kite1);

Answer 1

@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
final View result;
if (convertView == null) {

    viewHolder = new ViewHolder();
    LayoutInflater inflater = LayoutInflater.from(mContext);
    convertView = inflater.inflate(R.layout.rowsset, parent, false);
    imageView = (ImageView) convertView.findViewById(R.id.pic1);
    textView1 = (TextView) convertView.findViewById(R.id.det2);
    textView2 = (TextView) convertView.findViewById(R.id.kite1); 

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

viewHolder.textView1.setText(this.web[position]);
viewHolder.textView2.setText(this.web1[position]);
viewHolder.imageView.setImageResource(this.Imageid[position]);

// Return the completed view to render on screen
return convertView;
}

Answer 2

// Please this line mention in your adapter's constructor
inflater = LayoutInflater.from(context);

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

    convertView = inflater.inflate(R.layout.rowsset, null);
    imageView = (ImageView) list.findViewById(R.id.pic1);
    textView1 = (TextView) list.findViewById(R.id.det2);
    textView2 = (TextView) list.findViewById(R.id.kite1);
    textView1.setText(web[position]);
    textView2.setText(web1[position]);
    imageView.setImageResource(Imageid[position]);

    return convertView;
}

Hope this will work...
