I don't see where you are actually trying to delete anything. Please post those codes and what does/doesn't happen including errors. — codeMagic, Aug 02 '14 at 03:11

remove items from your arrays and then redraw your listview with notifyDataSetChange method — Farrokh, Aug 02 '14 at 03:21
like this VivzAdapter.this.notifyDataSetChanged(); Farrokh?? — user3755062, Aug 02 '14 at 03:24
@codeMagic i tried many codes but not to my success pls do suggest!!! — user3755062, Aug 02 '14 at 03:29
Since you are inside the anonymous class, you will probably need ` VivzAdapter.this.notifyDataSetChanged();` — codeMagic, Aug 02 '14 at 03:34
Why don't you use ArrayList instead of three different String Array. — Sumit, Aug 02 '14 at 08:12
What you have to do here is, on onItemClick get the position, and remove data at this position from all the string arrays, and then call adapter>notifyDataSetChanged(); — Sumit, Aug 02 '14 at 08:14

use this:

 final int listItemPosition = position;
 Button b=(Button)row.findViewById(R.id.cancelbutton);
 b.setOnClickListener(new View.OnClickListener() {


    @Override
    public void onClick(View arg0) {

    foodname.remove(listItemPosition);
    VivzAdapter.this.notifyDataSetChanged();

    }


    });

note that you can delete just foodname because that just passed to super constructor, I think you should declare objects and send that object to arraylist, like this :

class object {
String foodname;
String quantity;
String amount;
}

and use that like this

VivzAdapter(Context c,ArrayList<object>){

}

hope help you!!!

@user3755062: Did you have any problems getting your button to work on the very first row?? I am doing something similar to you but cannot get buttons to work on my top row.
