@Mark Murphy That's a good idea but my goal is to have the view only appear after screen inactivity. So I want/need the ability to cancel the scheduled animation.
@Romain Guy It has been my understanding and experience that a Handler object could be used to schedule things on the UI thread. Yet if I use a Handler, the behavior is the same as using the Timer (although that could be due to different causes). As I wrote before, I have tried a Handler and runOnUiThread() to little success. Although the problem hasn't been solved, thank you all for replying and replying so quickly.
