How to make Android share button appear on touch?
<p>I am creating a news app which contains a 'share news' button. Currently this button is showing all the time when user reads the news, which makes news reading irritating. Now my question is how can I make that share button show up when user touch on the screen, and will disappear after 2-3 seconds if it is left without touching. It would be nice if I can make a little animation during the button appearing/disappearing (like, show up from bottom and disappear going down). Please help...</p>

<p>Thanks</p>
