How can I prevent an IllegalStateException when I try to reuse a global variable?

Question

I have an activity which gets a page from the web and then parses it to a TableLayout that is inside a ScrollView.

Then I save the ScrollView into a global variable just like its described by Jeff Gilfelt in this post.

After this I leave my activity and enter it again and I check if there is a saved ScrollView in the global variable, and if there is I try to set it via setContentView().

The problem is that I get an IllegalStateException on the setContentView(savedScrollView); call.

Can anyone help me?

shouldn't you call removeView at some point before calling setContentView for the second time? — MarianP, Oct 20 '11 at 18:39

When activity is resumed, chances are good that it is still configured and does not need view setting. You shall set content view in onCreate() - not in onResume()
