    boolean music = getPrefs.getBoolean("checkbox", true);
    if (music == true)      
    ourSong.start();

    Thread timer = new Thread(){
       public void run(){
        try{

                  (Window.FEATURE_CUSTOM_TITLE,R.layout.custom_title);  
        TextView tv = (TextView) findViewById(R.id.title_tv1); 
         tv.setText("preference screen"); }

    addPreferencesFromResource(R.xml.preference);

                                        }
                        }

         addPreferencesFromResource(R.xml.preference);

在jelly bean设备上运行时

logcat：

更新：

如果我删除：MainActivity中的自定义标题：

   Boolean customTitleSupported = requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); 
    if (customTitleSupported) { getWindow().setFeatureInt
      (Window.FEATURE_CUSTOM_TITLE,R.layout.custom_title);

它在两台设备上运行良好，但我希望保留自定义标题。

最后它完美地运作：我在偏好主题中找到了解决方案，已经在明确表示如下：

 <activity android:name=".Prefs" 
           android:label="@string/app_name" 
           android:theme="@style/PreferencesTheme">

PreferencesTheme.XML：

<?xml version="1.0" encoding="utf-8"?>
 <resources xmlns:android="http://schemas.android.com/apk/res/android">
 <style name="CustomWindowTitleBackground" /> 
  <style name="PreferencesTheme" parent="android:Theme">
  <item name="android:windowTitleSize">35dp</item> 
  <item name="android:windowTitleBackgroundStyle">@style/CustomWindowTitleBackground</item>
   </style>   
 </resources>

PreferenceFragment支持所有API问题
