Custom notification screen over lock screen

I need single custom view that can be displayed from a service in order to display notifications over the lock screen. Requirements: The layout or view shall be displayed over the lock screen when a notification comes in. Each existing notification shall be displayed until there is no more room on the screen, with highest priority notifications at the top. For each notification the app icon and notification content text shall be displayed. A bonus will be awarded if the contacts photo can be displayed instead of the app icon for missed calls, emails, and text messages. Background color of the entire view shall be black. Notifications shall be in all white or gray scale with the option to use color. Holding a notification and dragging it down shall cause an X surrounded by a circle to appear. When the notification is released over the X, the notification shall be dismissed. If the notification is dragged up, the intent associated with the notification shall be fired in order to open the associated app. The view shall automatically be displayed each time a new notification arrives.
