How do I force RecyclerView to keep its views drawn?

Question

I have fragment in my app that acts as a portal to link to other fragments. The way I implemented this is by simulating a click on the nav drawer, which already handles all the code for switching fragments.

NavigationDrawerAdapter.ViewHolder v = (NavigationDrawerAdapter.ViewHolder) mDrawerList.findViewHolderForAdapterPosition(i);
v.itemView.performClick();

However, I get an error when I try to simulate a click on an item that isn't visible on the RecyclerView's current state. I know this is because RecyclerView only keeps visible views in its array of ViewHolders, but I need the ability to simulate a click on views that aren't in that array.

Yes, I know, I should just refactor my code so that I'm not doing janky things like simulating user clicks on the nav drawer. However, in the interest of time, and an understanding that this nav drawer will never really get incredibly big, as long as there are no other really negative caveats other than memory issues, I think it's the best working solution for the current state of my code.

Why not do a scroll to position that you need then the view will be drawn and you can do your click manually. Yes its ugly but what you are asking to do it ugly — tyczj, Mar 07 '16 at 17:53
@Sevle `ListView` recycles Views as well. It will not keep invisible positions. — Yaroslav Mytkalyk, Mar 07 '16 at 17:56

RecyclerView is intended to recycle Views. If you need to keep Views, use a ScrollView with a vertical LinearLayout.

You can probably scroll RecyclerView, wait for finishing and then simulate clicks. But anyway this whole thing seems wrong.

Have you considered NavigationView?

I concede that it's even more janky now, but scrolling first and then simulating the click worked in my case. – user2968367 Mar 07 '16 at 19:36
