Yes, you can. Just be careful. This is what Oracle documentation says:

If you create a trigger on a base table of a materialized view, then you must ensure that the trigger does not fire during a refresh of the materialized view. During refresh, the DBMS_MVIEW procedure I_AM_A_REFRESH returns TRUE.
