How to locate the preference category in a preference screen in Android?

Question

I implement a notification in the notification area, which can be clicked and go to the Sound Setting preference activity. There's several categories in this page, how can i scroll to a category or a preference item exactly I want? If I do noting and just start the Sound Setting, I can't see the category I want immediately.

Answer 1

If SettingsActivity is yours custom activity you can

getListView().setSelection(i);

if you mean native android sound settings I think you can't.

To scroll to certain category I think you must to do somethink like this

PreferenceCategory category = (PreferenceCategory)findPreference("you_category_key");
        for (int i = 0; i <  getPreferenceScreen().getRootAdapter().getCount(); i++){
            Object o = getPreferenceScreen().getRootAdapter().getItem(i);
            if (o instanceof PreferenceCategory ){
                if (o.equals(category)){
                    getListView().setSelection(i);
                }
            }
        }

But unfortunately this code has no effect in onCerate and onResume, dont know why. Try to past this code in other palces.
