title: How can I implementing sliding, overlay views on Android?
body: <p>I am working on a pdf reader application.  When the user touches the screen, two toolbars will slide into view, overlaid on top of the pdf.  There is one toolbar at the top of the screen and one at the bottom, that slide in from off-screen when touched.  What is the best way to go about implementing this?  I've been having trouble finding any code examples for something similar.  Thanks for your help.</p>
