I've got a very similar app I'm doing now, I replied to your other
post as well, just to point out that I'm also using onActivityResult
however instead of invalidate I just force the activity to launch
again. I track which tab they were on before they launched the
activity which created the new record so when it comes back to this, I
know which tab to set it to with the setCurrentTab. It sounds really
inefficient (and it is) but so far with some big lists I am getting
really good results. And of course, you've already got it where you
don't redraw when there was nothing edited or created.
