moving an item depending on scroll amount of dynamic panel?
I'm creating an Android App prototype with App Bar at the top, and a long content beneath it in a dynamic pane that is a exactly device screen size.
What I'd like to do is pushing away AppBar out of the screen and bringing it back depending on scroll amount of contents in a dynamic panel. So as a user, while consuming contents as scrolling up, App bar is out of screen and when s/he scrolls back up, Appbar comes back to the screen.
1. Put 'On Scroll' event on AppBar with condition 'if SY > 0'
2. " 'If absolute position of the dynamic panel < 0'
None of them worked. Is there anyone can help me out with this issue? I can't find any similar questions answered.
