Question

Is there a way to find out when the user closes a particular preference screen? I need to do some updating when the user has changed the preferences in one of my preference screens. Not when the user clicks an actual checkbox, but rather when they press the back button and are done editing the preferences.

So far, all I’ve been able to find is that I can override my PreferenceActivity’s onPause() event, which seems to happen when the user closes the preferences. It works, but I’m not sure this is the best way of going about it. Any suggestions?

EDIT

I couldn’t figure out how to actually call a method of my main activity from within the PreferenceActivity. Tried playing around with putExtra() and all sorts of stuff. Eventually i figured – why not do the completely opposite? So instead I implemented the onResume() method in my main activity. Works great for doing stuff when the user closes the preferences, and I can live with the fact that my update method runs every time I resume my app as well.

That’s the best way to go about it: overriding the onPause() method. It’s called right before your activity leaves the foreground.
