What do you mean by "hearsay"? I suspect that you don't quite understand what hearsay is.
It is NOT hearsay for an officer or other witness to testify as to what the defendant said or did. It IS (or might be - depending on the circumstances and state law) hearsay for an officer or witness to testify as to what someone ELSE told them that the defendant did.
The elements of what might be "disorderly conduct" vary by state. My state does not have such a statute though there are times I wish we did. Fortunately, most people that tend to act so crude and obnoxious that we get called tend to be inebriated to a point where THAT can be a crime.
