Other possibility of refresh data in a CursorAdapter backed ListView is to create a new cursor and call swapCursor on CursorAdapter.

  cursor = newCursor();
  ((CursorAdapter) getListAdapter()).swapCursor(cursor);

Hope this can help.

Try like this,,

@Override
public void bindView(View view, Context context, final Cursor cursor) {

    TextView txtName = (TextView) view.findViewById(R.id.txt_name);
    txtName.setText(cursor.getString(cursor.getColumnIndex(Helper.tbl_col_username)));
    TextView txtPassword = (TextView) view.findViewById(R.id.txt_password);
    txtPassword.setText(cursor.getString(cursor.getColumnIndex(Helper.tbl_col_password)));

final String itemId = cursor.getString(cursor.getColumnIndex("id"));

    Button button = (Button) view.findViewById(R.id.btn_delete);
    button.setOnClickListener(new OnClickListener() {

        public void onClick(View arg0) {
            Log.d(TAG, "Button Click ");
            deleteRecordWithId(itemId);
            cursor.requery();
            notifyDataSetChanged();
        }
    });
}
