RingtonePreference defaultValue InflateException

我使用RingtonePreference並希望使用默認通知聲音作爲默認首選項值。爲了達到這個目的，我遵循以下建議：RingtonePreference Default value RingtonePreference defaultValue InflateException

不幸的是，實際上我得到了一個我無法以任何方式擺脫的InflateException。它是Android中的錯誤，我的手機還是我做錯了什麼？

我OnCreate方法MyPreferenceActivity類：

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    addPreferencesFromResource(R.xml.preferences); 
}

我也試過將一個字符串DEFAULT_NOTIFICATION_URI：

<RingtonePreference 
     android:key="ringtone_preference" 
     android:ringtoneType="notification" 
     android:showDefault="true" 
     android:showSilent="true" 
     android:defaultValue="content://settings/system/notification_sound" 
     android:title="Notification sound" 
     android:summary="" 
     />

異常的logcat的而不是content://settings/system/notification_sound，但沒有任何成功。在完全刪除android:defaultValue字段之後，除了事實之外，一切都正常工作，我的首選項的默認值是默認通知聲音的靜音鈴聲，這對我來說是不可接受的。

我到處搜索並找不到解決此問題的方法。如果沒有其他工作，我會使用一個黑客發佈在這裏：https://stackoverflow.com/a/4298638/1265432，但我想解決這個問題。

編輯：我的CM9摩托羅拉Defy和仿真器4.0.4（API 15）和2.1（API 7）存在問題，所以我認爲手機不是問題。錯誤，或者我做錯了什麼？

如果您記錄'Settings.System.DEFAULT_NOTIFICATION_URI'常量的值，那麼它是否與您期望的相同？如果是這樣，它看起來像一個Android錯誤。如果不是，那麼它只是將其值從設備/ API更改爲設備/ API，然後唯一的方法是以編程方式進行設置。 –

是的，'Settings.System.DEFAULT_NOTIFICATION_URI ==「content：// settings/system/notification_sound」' – stanwise

我提交了一份bug報告爲Android瀏覽：http://code.google.com/p/android/issues/detail?id=33220

在此期間，我用以下解決方法，我發現一個比這個問題掛鉤清潔。我修改的MyPreferenceActivityOnCreate方法是：

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    Uri notificationSound = Uri.parse(PreferenceManager.getDefaultSharedPreferences(this) 
    .getString("ringtone_preference", System.DEFAULT_NOTIFICATION_URI.toString())); 
    if (notificationSound.equals(System.DEFAULT_NOTIFICATION_URI)) { 
     PreferenceManager.getDefaultSharedPreferences(this).edit() 
      .putString("ringtone_preference", System.DEFAULT_NOTIFICATION_URI.toString()) 
      .commit(); 
    } 

    addPreferencesFromResource(R.xml.preferences); 
}

我對你的錯誤報告對什麼問題還真是有些見解的評論。

反正這裏有一個簡單的解決方法是對我的作品：

添加默認值的MultiSelectListPreference RingtonePreference後到來在你的喜好XML：

<MultiSelectListPreference 
     ... 
     android:defaultValue="@array/empty" 
     ... 
     />

而且在strings.xml：

<string-array name="empty"/>
