How to properly interact with the adapter?

Question

Android

I am trying to hide fields on button click. If I do this in the adapter (click on the itemView), then everything works as it should. If I try with the button, it doesn't work.

In general, in this case, it is correct to change the dataset, and notify the adapter about the change so that it rebinds the viewholder, otherwise it will turn out to be crap.
