@Josh - 好答案

@Josh - Good answer.

我想补充为完整起见是，你应该设定让您注册在preferenceActivity的onResume（）方法的变化，并在注销的onPause（）方法。

I'd like to add for the sake of completeness is that you should set things up so you register for changes in your PreferenceActivity's onResume() method and unregister in the onPause() method.

另外，您也可以注册听众为每个在活动的onCreate（在preferences），并分别处理它们的事件。
