Narrative:

I had taken a load in the aircraft and taxied to runway xx at ZZZ. There were 2 airplanes in the pattern for runway xy; cessna 172 and a bonanza. The cessna 172 was on base for [runway] xy planning a touch and go and the bonanza was across midfield for a downwind entry to [runway] xy. My plan was to taxi into position; wait until the cessna 172 had passed by and then takeoff. I announced those plans on frequency. I heard the cessna 172 acknowledge my radio call. I then thought that the cessna 172 told me that they were on short final and would hold short of [runway] xx. I acknowledged that call and replied that I was rolling on [runway] xx. I proceeded with my takeoff and as I crossed runway [runway] xy I saw the cessna 172 go over me after taking off on [runway] xy. We crossed paths and I estimate we cleared by about 150 feet. I later called the pilot of the cessna 172 by phone to find out what happened. He said that he never said that he would hold short; but intended to do a quick touch and go in order to get past runway [runway] xx and let me depart. Apparently; I misunderstood his radio call. This was my fault in that I misunderstood his intentions and was only using his radio calls to determine his position. I did not have the cessna 172 in sight when I started my takeoff. If I would have held position until I had visual contact then this could have been avoided.
