Search only 1 record in SQLite

I have the following method to fetch the bank records, and use them in a ListView , Spinner , etc:

public ArrayList<CRegistros> getRegistros() {
    sqLiteDatabase = banco.getReadableDatabase();
            ArrayList<CRegistros> arRegistros = new ArrayList<>();
            Cursor cursor = sqLiteDatabase.rawQuery("SELECT *, rg._id _id, cl.nome cliente, sl.nome solicitante " +
                    "FROM registros rg " +
                    "LEFT JOIN clientes cl ON cl.handle = rg.cliente " +
                    "LEFT JOIN solicitantes sl ON sl.handle = rg.solicitante " +
                    "ORDER BY data DESC, hora DESC, _id DESC", null);

            if (cursor != null && cursor.moveToFirst()) {
                do {
                    Integer _id = cursor.getInt(cursor.getColumnIndex("_id"));
                    Integer tipo = cursor.getInt(cursor.getColumnIndex("tipo"));
                    String data = cursor.getString(cursor.getColumnIndex("data"));
                    String horario = cursor.getString(cursor.getColumnIndex("hora"));
                    String historico = cursor.getString(cursor.getColumnIndex("historico"));
                    Integer veiculo = cursor.getInt(cursor.getColumnIndex("veiculo"));
                    Double km = cursor.getDouble(cursor.getColumnIndex("km"));
                    String cliente = cursor.getString(cursor.getColumnIndex("cliente"));
                    String solicitante = cursor.getString(cursor.getColumnIndex("solicitante"));
                    String finalizado = cursor.getString(cursor.getColumnIndex("finalizado"));

                    CRegistros registros = new CRegistros(_id, tipo, data, horario, historico, veiculo, km, cliente, solicitante, finalizado);
                    arRegistros.add(registros);
                } while (cursor.moveToNext());
            }
            return arRegistros;

I need to pull only 1 record, so I can edit it, and I have _id of the record for this search.

I would like to know if to search only 1 record, would it be all this process how do I generate this ArrayList or would it have a "simpler, more efficient" way to do this?
