Android, perform action when widget is clicked

Can someone provide me with an example of how to perform an action when the user taps on a widget? The only example I have found launches an activity. I assume that it must still do it with some sort of pending intent 开发者_如何学编程and maybe a broadcast receiver, but I'm not sure how to do it.

Call RemoteViews.setOnClickPendingIntent on the views in your widget (assuming you have views in your widget).
