How to insert data from multiple fragments into a single database row in a single table?

I am relatively new to Android and even more amateur as long as it concerns database architecture. What I'm trying to accomplish is fairly simple and I'm trying to accomplish without adding more tables or unnecessary complexity.

I have five fragments with their respective layouts which are accessed in a linear manner by the user. In each fragment the user inputs a single form of data, either it is a String, or a checked radio button etc.

I attempted various tweaks but the majority of them end up that each fragments creates its own row. Should I probably write an insert method for each fragment data? I believe that this is a fairly simple solution, if that is the case forgive me for my ignorance. Thanks!
