I am making an app which has a main recycler view and an internal recycler view that goes inside the main recycler view. The problem is that the list of elements is not displayed inside the recycler view, I have tried several things that you mention in this forum but I have not had good results. I read about nestedscrollview but it has not worked either, the last thing I tried was what I leave you in the code. This works but it is not efficient since in the emulator there are times when paste the scroll view (so the data is displayed "in jerks"
