RingtonePreference未触发OnPreferenceChangeListener

Question

我发布的其他所有首选项都会触发其OnPreferenceChangeListener.但是,我的RingtonePreference它没有:

p = getPreferenceScreen().findPreference("pref_tone");
String rname = preferences.getString("pref_tone",Settings.System.DEFAULT_RINGTONE_URI.toString());
String name = ringtoneToName(rname);
p.setSummary(name);
p.setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
public boolean onPreferenceChange(Preference preference, Object newValue) {
    // Never hits here!
    String v = (String) newValue;
    preference.setSummary(ringtoneToName(v));           
    return true;
}
});

onActivityResult不得不调用super.onActivityResult是修复
