If you want to programmatically filter using GlazedLists you need to pass a Matcher or MatcherEditor to the FilterList. If you have also the filter row in place that would interfere with the defaults. For such cases we have the DefaultGlazedListsStaticFilterStrategy where you can pass a Matcher that works in combination with the filter row.

Then pass the matcher directly to the FilterList. There is no default implementation for that. You have to impl it yourself

Here's my code
EventList eventlist =new BasicEventList(myDatas);
Matcher matcher =new FilterMatcher(myDatas);
FilterList filterlist =new FilterList (eventlist,matcher);
DefaultGlazedListStaticFilterStrategy strategy = new DefaultGlazedListStaticFilterStrategy (filterlist,accessor, new ConfigRegistry());
strategy.applyFilter(map);
but it didn't work. the filterlist's size always is 0.

I thought you don't want to use the DefaultGlazedListStaticFilterStrategy. If you don't want the filter row it is not needed. You only need the matcher on the FilterList.

Probably the Matcher is not correct. For example I don't understand why you pass the FilterList as parameter. Check for the GlazedLists documentation to see how plain filtering works.
