躲在偏好屏幕（機器人）

我試圖隱藏我的偏好設置屏幕的標題欄中的標題欄，但通常requestWindowFeature(Window.FEATURE_NO_TITLE);躲在偏好屏幕（機器人）

不工作了，有什麼建議？

我的代碼是：

對於我的清單：

<activity 
      android:name=".prefs" 
      android:label="@string/app_name" 
      android:theme="@android:style/Theme.NoTitleBar"> 
      <intent-filter> 
       <action android:name="com.mittereder.rockpaper.PREFS" /> 

       <category android:name="android.intent.category.DEFAULT" /> 
      </intent-filter> 
     </activity>

的Java：

protected void onCreate(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     super.onCreate(savedInstanceState); 
     addPreferencesFromResource(R.xml.prefs); 
     requestWindowFeature(Window.FEATURE_NO_TITLE);

的logcat：

您可能會錯過「>」或「/>」中的活動標籤，同時ü編輯它。請驗證它... :) – 2012-08-10 04:13:17

？我認爲它只是選中了一點:) – 2012-08-10 04:14:13

試試這個：

@Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     requestWindowFeature(Window.FEATURE_NO_TITLE); 
     this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 
     addPreferencesFromResource(R.xml.myPreferences); 

    }

在清單：

<activity android:name=".MyPreferencesActivity" 
        android:label="@string/app_name" 
        android:theme="@android:style/Theme.Light.NoTitleBar">

我試過了，我的應用程序崩潰了，我發佈logcat在我的編輯 – 2012-08-10 04:09:22

發佈日誌時，應用程序崩潰 – 2012-08-10 04:10:47

發佈它在我的編輯上面 – 2012-08-10 04:12:02

已設置的主題爲android系統中的活動表現如下...

<activity android:name=".Login" android:theme="@android:style/Theme.NoTitleBar" />

請在編輯它之後驗證您的活動標記。

我把android：theme =「@ android：style/Theme.Light.NoTitleBar」就像一個魅力<3謝謝！ – 2012-08-10 04:31:26
