They are not as they both have the same features it just provides a better understanding when using one diagram in conjunction with the other.
State machine diagram shows how state of some object or system could change, so transitions on the diagram are from one state to another state.
Activity diagram shows set of actions and how one action could lead to another.
In simple cases these diagrams might look like reverse of each other but in practice you need to select whether the diagram is about discrete number of states of some object or is it about organization of actions and activities possibly related to many different objects.

∙ 9y agoState diagram shows the object undergoing a process. It gives a clear picture of the changes in the object's state in this process.
e.g: ATM withdraw
Card object state: Checking, Approving, Rejecting
Activity diagram is a fancy flow chart which shows the flow of activity of a process.
e.g: ATM withdraw
Withdraw activity: Insert Card, Enter PIN, Check balance, with draw money, get card
State chart shows the dynamic behavior of an object.
Activity diagram shows the workflow behavior of an operation as set of actions

What is the difference between activity diagram and sequence diagram?
Activity diagram shows the work flow from start point to the end point detailing many decision points. Sequence shows detail flow of specific use case and it also shows interaction between actors, system and system components

What is the difference between sequence diagram and state diagram?
State diagram represents behavior without noting the classes involved whereas sequence diagram represents behavior, by describing how classes move from state to state

What is a state diagram?
A state diagram is a type of diagram used in computer science and related fields to describe the behavior of systems. State diagrams require that the system described is composed of a finite number of states; sometimes, this is indeed the case, while at other times this is a reasonable abstraction. Many forms of state diagrams exist, which differ slightly and have different semantics.
