Transitioning from ABS Pipe to PVC Trap

I changed my sink yesterday, and I decided to also go ahead and change the trap. I thought it would be a simple swap, but it turned out to be more complicated. The new one was shorter, so the tailpiece didn't line up correctly. Is it possible to transition from the ABS pipe to a PVC trap? My plan is to cut the old trap off and attach an ABS 1 1/2" adapter fitting to the ABS using ABS cement. From there, I will attach the new PVC trap to the ABS fitting/slip joint connector. Is this acceptable, or is there another way to accomplish this? I am very new to plumbing, so I apologize if my terminology isn't accurate.

Yes, you are on the right track. You need about 1" of good pipe to glue the trap adapter onto the pipe coming from wall. Make your cut as square as possible and sand off any burs. Here's the trap adapter you need:

Apply the abs cement to the outside of the pipe and the inside of the adapter hub. Twist it a little while pushing it on.
