I have an application like a one-column calendar. And I'd like to draw a line at the top (from left to right) so it goes down as minutes pass, so it would indicate which part of the calendar is being executed now, more or less. I've searched it, but when I draw the line, it hides all the application (maybe because the view where the line is drawn is drawn above the main view). I'd like 2 different views: one for my application, and the other one (relativelayout?) to contain the time line and going down without hiding the rest of the main app.

thanks!!
