java - Check enter and leave Preferences -
i'm using preferencefragment , headers manage application settings in official tutorial: http://developer.android.com/guide/topics/ui/settings.html#fragment
you can call preferences actionbar in several activities.
now want detect, if user enters oder leaves preferences. how can that?
my approach using lifecycle methods like: oncreate, onresume, onpause ....
but there solution listener or else?
you can override onbackpressed on preferencefragment call interface method implemented on caller/s activity.
that way can notify need activitys.
public interface preferenceinterface { public abstract void preferencesclosed(); public abstract void preferencesopened(); }
i hope looking for.
