Android: how to get notified when a widget is tapped

I would like to get a notification when the user taps/clicks on a widget?

Is there something similar开发者_JAVA百科 to onClick()?

You must use AppWidgetProvider and register listeners there. Since in Widgets all view are created via RemoteViews you must use methods on them - e.g. setOnClickPendingIntent().
