getDefaultSharedPreferences in a BroadcastReceiver

问题

I was just guessing how to access the DefaultSharedPreferences (set in a PreferenceActivity) from an application in a BroadcastReceiver, knowing that onReceive method comes with Context and Intent?

Best regards,

回答1:

In the BroadcastReceiver:

PreferenceManager.getDefaultSharedPreferences(context)

回答2:

Looking at the source of it, we can see getDefaultSharedPreferences actually uses getSharedPreferences. So we can use getSharedPreferences the same we getDefaultSharedPreferences uses it.

In this specific case (onReceive of a BroadcastReceiver) :

SharedPreferences settings = context.getSharedPreferences(context.getPackageName() + "_preferences", Context.MODE_PRIVATE);
