Yes, the first two options are a bit unpleasant, and as for the third, well
its an option but I couldn't help feeling there had to be a better way.
After some more thought I ended up adopting a slightly different approach
altogether. I took out the two mutually exclusive sets of preferences and
put them in two other preference files, 'a' and 'b'. Then I created a
separate, new preference activity (MorePreferences, below) that in the
onCreate method loaded 'a' or 'b' based on my checkbox preference value:
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final int preferences;
if (Preferences.isPreferencesA(this)) {
preferences = R.xml.
}
else {
preferences = R.xml.
}
addPreferencesFromResource(preferences);
}
In the main preferences I put a PreferenceScreen entry in, which uses an
intent to fire up the new preference activity - when activated it loads the
right set of preferences:
<PreferenceScreen android:title="@string/announcement_settings"
android:summary="@string/announcement_settings_summary">
<intent
android:action="android.intent.action.MAIN"
android:targetPackage="mypackage"
android:targetClass="mypackage.MorePreferences"/>
</PreferenceScreen>
