Here’s the deal: I have a heavy layout that cannot be improved any further, as it contains LinearLayouts with weights (so I cannot use RelativeLayouts).
In Activity A, I click on a list item that fires off Activity B. Activity A freezes until Activity B is fully loaded, then Activity B gets shown. So this is the complete queue of events:

  1. Activity A: open B
  2. Activity A: freezes
  3. Activity B: finishes inflation/setContentView
  4. Activity A: goes back into the application stack
  5. Activity B: gets shown

How can I immediately show Activity B so that Activity A won’t freeze?
I thought about inflating a temporary layout in B, but I need a callback method that tells me that B is fully visible and I can then replace the temporary layout with the real one.

Can anyone help me?
Thank you!

Off topic: layout inflation in Android is a real pain, it shouldn’t block the whole UI, but it does. Same thing for setting list adapters.

    You should do your time taking task of Activity B in thread and if you need to update the UI after your task completes then do it using handler.
