I am making an application where I write my daily income. I have a row design and a Fragment design page. I show the data I entered in the adapter in the recyclerRow, but at the bottom of this list I have a total line where I collect the columns and I want to write the total of each column in this line, but this last total line is under the recyclerView image on the fragment design page, I tried to access this total line from the adapter, but unfortunately the application crashed every time.

I asked many people but I couldn't find an answer, someone told me to use Interface but I couldn't figure out how to use it
