Question

I’m trying to use the requestWindowFeature() function to set a custom title view on a list activity. The method works fine with a view that only subclasses Activity, but whenever I try the same method with a ListActivity subclass, it errors, giving me a NullPointerException when I try to programmatically modify the title view.

I believe the problem pertains to the fact that requestWindowFeature() needs to be called before setContentView(). Because ListActivity takes care of setting the content view for you, I don’t know when that is being called. Does anyone have any suggestions? Thanks for the help.

Answer 1

setContentView is called whenever you interact with the List, for example calling getList() or setAdapter() on listactivity. See the source of listactivity
