Well, the recommended approach is to use a StateListDrawable for the tab icon, so it changes its look based on selected/not-selected and such. As you have notices, there is no API to change the tab once it has been defined. You can navigate the view hierarchy with a well-crafted set of findViewById() calls to get to the ImageView, but this will be fragile -- if they change the implementation in a future edition of Android, you're screwed. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Warescription: Three Android Books, Plus Updates, One Low Price! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
