How to Create Clickable on Icon in Status Bar to Run Function/Method/Code

Question

Okay, this would be fairly simple in some other environments, but I can't figure out how to do it, or if its even possible in Android.

I have placed an icon on the status bar. I would like to run a method of another class whenever the user selects that icon. I've seen similar functionality used in volume icons that sit on the status bar that allow a user to raise or lower the volume when the icon is clicked. However, these icons are on the right side of the status bar, and from what I've seen, I'm not allowed to put an icon there. I don't know if that kind of functionality is available to left side icons.

So basically, I'm looking for how to run a function when a status bar icon is clicked. I don't want to open an activity, I just want to run a function.

What you're searching is probably related to the Android UI ActionBar pattern.

Regarding that I'd like to consider you to take a look at the Google I/O 2010 Android app. It contains many of these patterns and may help you out.

Summarizing, you have to create your own ActionBar (or Status Bar as you call it). You place your buttons, retrieve them via the findViewById(...) method and associate a click listener.
