Do we have to request focus on each touch event? Also, I noticed that the focus change listener we add in the activity here never gets called. Could this be related to the current issue?

I'm having trouble imagining what alternatives there are to requesting focus on input. Also, the focus listener is definitely called in my testing—how are you determining that?

My concern was that requestFocus might be too costly to be called on every touch event, so maybe there could be an alternative where we requestFocus only when we know the view doesn't have it already. I don't know about the actual cost of requestFocus though.

Yep, it does get called. I was using assert false as the body, but I didn't realize assertions are disabled in release builds. The debug build confirms that it is called.
