Narrative:
While between ric and dca first officer accidentally hit the landing gear lever. Gear deployed with aircraft in flight at 280 KTS at 22000 ft MSL. Immediately retarded the thrust levers to slow aircraft to below 250 KTS and retarded gear lever to up position landing gear lever disagree message appeared on EICAS when gear retracted. Slowed aircraft to below 250 KTS, referenced the cfm. Per the cfm, recycled the landing gear. EICAS message still displayed. Returned gear to down position and all indications were normal. Declared emergency and continued to dca and landed without incident.
