I am interested in creating the following effect: a gradient (dark grey) overlay with icons over the Android Video Player on the phone. How could I achieve this? Also, how can I make this overlay/gradient fade away after a certain amount of idle time? Thank you.

Sure. Here's the XML snippet for the overlay
I put the 'overlay' at the end of the entire layout so it is on top. I set it initially to "gone" so it doesn't show up. Then in my Java,
If your layout the view resides in, in my case a LinearLayout, has "animateLayoutChanges' set to true, then the default animation when I set the overlay to gone is to simply fade away. Very easy peasy
