Accessing multiple shared preferences
I basically want to be able to have multiple SharedPre开发者_StackOverflowferences files for my app. The names of these will be based off of a string entered by the user. Then when the user wants to restore, I want to create a popup that will allow them to pick from all available SharedPreferences files. Is there a way to see what SharedPreferences files are in the directory? Or is there a better way to store this?
TIA
You could save a csv list of SharedPreferences as a SharedPreference...
But I think if you are going to have multiple configurations, better approaches would be either a small SqliteDatabase or ".ini" files in the internal storage.
If you insisted on using SharedPreferences as the storage mechanism, what you could do is use the default shared preferences (get it with SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
) to store a list of the preference files created (using something like the putStringSet
method at http://developer.android.com/reference/android/content/SharedPreferences.Editor.html#putStringSet%28java.lang.String,%20java.util.Set%3Cjava.lang.String%3E%29). You can then retrieve them later and generate the popup list.
