I have a PreferenceScreen child element (containing the ZonePicker fragment) in the following .xml:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
    android:title="@string/DateTimePreferencesTitle">
   <CheckBoxPreference android:key="cb_pref"
       android:title="@string/cb_pref_title"
       android:summaryOn="@string/summaryOn"
       android:summaryOff="@string/summaryOff"
       />
       .
       .
       .
   <PreferenceScreen
       android:fragment="com.trimble.ag.amaethon.preferences.ZonePicker"
       android:key="timezone"
       android:title="@string/date_time_set_timezone"
       android:summary="GMT-8:00"
       />
</PreferenceScreen>
The ZonePicker fragment extends ListFragment. I am trying to find a way to get at the above PreferenceScreen element and change the android:summary value from within the ZonePicker fragment.
Any ideas?
