設定画面でタイトルバーを非表示にしようとしていますが、通常はrequestWindowFeature(Window.FEATURE_NO_TITLE);

うまくいかない、何か提案はありますか?

私のコードは次のとおりです。

私のマニフェストの場合:

<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>

ジャワ:

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

次のように、Androidマニフェストでアクティビティのテーマを設定しました...

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

編集後、アクティビティ タグを確認してください。

これを試して:

@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);

    }

マニフェストで:

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