Did you call notifyDataSetChanged() on adapter, after updating the listview? — Shaiful

I am posting code for deleting item from listview which is working correctly in my code.

You forgot to call notifysetchanged thats it.

    @Override
public View getView(int position, View convertView, ViewGroup parent) 
{
    View row = null;
    LayoutInflater inflater = getLayoutInflater();

    row = inflater.inflate(R.layout.one_result_details_row, parent, false);

    // inflate other items here : 
    Button deleteButton = (Button) row.findViewById(R.id.Details_Button01);
     deleteButton.setTag(position);

    deleteButton.setOnClickListener(
        new Button.OnClickListener() {
            @Override
            public void onClick(View v) {
                Integer index = (Integer) view.getTag();
                items.remove(index.intValue());  
                notifyDataSetChanged();
            }
        }
    );

plz have a look at the following answers

1) Remove ListView items in Android

2) Remove selected item from ListView

Let me know if you are still facing any issue...

Thanks
