public class ImageGridAdapter extends BaseAdapter{
private Context mContext;
private int mIconSize;
private static LayoutInflater inflater=null;
AdapterCallback callback;

public interface AdapterCallback{
   void onItemClicked(int position);
}

private String[] web = {
        "Doctors","Movies","Dentists","Restaurants","Car"} ;

private int[] imageId = {
        R.mipmap.doctors,
        R.mipmap.dentists,
        R.mipmap.restaurants,
        R.mipmap.carmechanic,
        R.mipmap.ic_launcher
};

public ImageGridAdapter(Context mContext, int mIconSize, AdapterCallback callback) {
    super();
    this.callback = callback;
    this.mContext = mContext;
    this.mIconSize = mIconSize;
    inflater = ( LayoutInflater )mContext.
            getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return imageId.length;
}

@Override
public Object getItem(int position) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return 0;
}

public class Holder
{
    CheckBox ck;
    ImageView img;
}

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

    Holder holder=new Holder();
    View rowView;

    rowView = inflater.inflate(R.layout.sell_main_images, null);
    holder.ck=(CheckBox) rowView.findViewById(R.id.chk1);
    holder.img=(ImageView) rowView.findViewById(R.id.imageView1);

    holder.ck.isChecked();
    holder.img.setImageResource(imageId[position]);

    rowView.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            // How do I introduce a callback to Fragment class with the item reference that has been clicked so that capture/loading images can be performed from the Fragment class?
              if(callback != null) {
                callback.onItemClicked(position);
                 }

        }
    });

    return rowView;
}

}
