(メモ)SimpleCursorAdapterでパラメータを途中でいじってからビューに渡したい時

(サンプルコード)今作り掛けのコードのスレ覧の断片
2chではスレID=立った時間のtime_tなのでDBにはスレIDで保存してるけど、表示は時刻表示したいみたいな話

ListAdapter adapter = new ThreadListCursorAdapter(
    this,
    R.layout.threads_list_row,
    cursor,
    new String[] {
        BoardsDbAdapter.KEY_THREAD_NAME,
        BoardsDbAdapter.KEY_THREAD_ID
    },
    new int[] {
        R.id.thread_list_name,
        R.id.thread_list_timestamp
    }
);
setListAdapter(adapter);

(中略)

static class ThreadListCursorAdapter extends SimpleCursorAdapter {
    static class ThreadListViewBinder implements SimpleCursorAdapter.ViewBinder {
        private SimpleDateFormat format;
        public ThreadListViewBinder() {
            format = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
        }
        @Override
        public boolean setViewValue(View view, Cursor cursor, int column_index) {
            int thread_id_index = cursor.getColumnIndex(BoardsDbAdapter.KEY_THREAD_ID);
            if (column_index == thread_id_index) {
                int thread_id = cursor.getInt(thread_id_index);
                Date date = new Date((long) thread_id * 1000);

                TextView text_view = (TextView) view;

                text_view.setText(format.format(date));

                return true;

            }

            return false;

        }

    }

    public ThreadListCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to) {

        super(context, layout, c, from, to);

        setViewBinder(new ThreadListViewBinder());

    }

}
