每隔preference我有触发其在preferenceChangeListener。然而，我的铃声preference它不会：

  P =获取preferenceScreen（）找到preference（pref_tone）;
串RNAME = preferences.getString（pref_tone，Settings.System.DEFAULT_RINGTONE_URI.toString（））;
字符串名称= ringtoneToName（RNAME）;
p.setSummary（名称）;
p.setOn preferenceChangeListener（新在preferenceChangeListener（）{
在preferenceChange公共布尔（preference preference，对象为newValue）{
    //永远不要打了！
    串V =（字符串类型）newValue;
    preference.setSummary（ringtoneToName（ⅴ））;
    返回true;
}
}）;
 

解决方案

onActivityResult只好打电话super.onActivityResult是修复

Every other preference I have fires its OnPreferenceChangeListener. However, my RingtonePreference it doesn't:

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;
}
});

解决方案

onActivityResult had to call super.onActivityResult is the fix
