Individual Preferences for each item in a ListView?

问题

I'm creating my first android app (or attempting to anyway) and i have a question i can't seem to find the answer to.

I would like to allow users to enter a separate set of preferences for each item in a list view. I have the PreferenceScreen working, but it maintains the same preferences for every item (i.e. changing 1 item results in changes to all others as well).

To give a more detailed example: Say i have a list of cars: * Car 1 * Car 2 * Etc...

I would like to be able to click on "Car 1" and get a PreferencesScreen to specify "Make", "Model", "Color" for just that car, instead of having those entries stored globally for the whole app.

Is this possible?

Thanks for your help!

Solved it!!

For any wondering, the solution is that you must call

getPreferenceManager().setSharedPreferenceName(value) with a value unique to the item you'd like to modify the preferences for (in my case, i used the ListView position) prior to calling addPreferencesFromResource.

getPreferenceManager() deprecated on api 11

Now with honeycom and ICS the method getPreferenceManager() is deprecated. Do you know how to do that with the new (PreferenceFragment + Headers)?

Thanks men! It works perfect in earlier versions!

UPDATE: Up to api level 11 is the same method but you have to call it on a Fragment, not on activity.
