It seems like you won't get the proper hook into the WebView for changing
its contents on load, if you load tab's content by id.
I was able to make this work using TabContentFactory. For sample code see
the ApiDemos/Views/Tabs sample.
On subsequent tab clicks you could change the content dynamically using
OnTabChangeListener.
