I have a Honeycomb style preferences. I define the headers:

```
<preference-headers xmlns:android="http://schemas.android.com/apk/res/android">
  <header android:id="@+id/pref_general" android:fragment="MyPreferencesFragment" android:title="@string/pref_general_title">
    <extra android:name="resource" android:value="pref_general" />
  </header>
  <header android:id="@+id/pref_sharing" android:fragment="MyPreferencesFragment" android:title="@string/pref_sharing_title">
    <extra android:name="resource" android:value="pref_sharing" />
  </header>
</preference-headers>

```

Then I load them in PreferenceActivity:

```
public void onBuildHeaders(List<Header> target)
{
  loadHeadersFromResource(R.xml.preference_headers, target);
}

```

How can I then address exact Fragment by its ID in startPreferenceFragment? How can I access a list item corresponding to that Fragment so I can enable/disable it?
