Answer 1

Date filed in the SQLite table will be TEXT and date data should be stored as "2012-12-31 00:12:00" format that comparison dose not give you trouble and if we consider that fields are date_from and date_to and we are storing current date at to_date then we should get the current date as bellow and

        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String to_date = sdf.format(new Date());

and the SQL query should be

    crs = db.rawQuery(
      "SELECT _id, date_from, date_to, done_or_not, list_name " +
      "FROM list_tbl " +
      "WHERE " +
      "date_from <= Datetime('"+to_date+"') AND date_to >= Datetime('"+to_date+"')", null);
