How to add setOnclick in Base adapter for Listview

Question

I want to add a call button in list view. I have tried adding the button in the list row file and cannot add Onclick on a Java file. There are more errors happening. Are there any other methods without button? Anyone please help me. Thank you.

Here is the Adapter code

class adapter extends BaseAdapter {
        LayoutInflater Inflater;
        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            return place.size();
        }

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

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

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub
            Inflater=(LayoutInflater)getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView=Inflater.inflate(R.layout.blood_lst,null);
           Viewholder holder=new adapter.Viewholder();

            holder.pl=(TextView)convertView.findViewById(R.id.bld_name);
            holder.pl.setText(place.get(position));

            holder.in=(TextView)convertView.findViewById(R.id.bld_nm);
            holder.in.setText(incharge.get(position));

            holder.em=(TextView)convertView.findViewById(R.id.bld_em);
            holder.em.setText(email.get(position));

            holder.ph=(TextView)convertView.findViewById(R.id.bld_phn);
            holder.ph.setText(phone.get(position));

            holder.ph=(TextView)convertView.findViewById(R.id.bld_grp);
            holder.ph.setText(Bld.get(position));

            return convertView;
        }
        class Viewholder{
            TextView pl;
            TextView in;
            TextView em;
            TextView ph;
        }
    }
}

Add a onClick to the convertView like so:

convertView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        // do stuff here
    }
});
