所以我正在開發一個替代lockscreenapp 推出，我需要防止點擊notificationbar的Android全屏幕不能正常工作時，活動由服務
所以我儘量在fullscreenn
但是，當運行這個程序它是大道由notificationbar仍然是他們當它被髮射稱之爲得到無形 代碼服務： 公共類的應用程序擴展活動{

我也用鍵盤鎖 全屏在我的清單中實現：
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
android:name=".app"
android:label="@string/app_name"
android:screenOrientation="portrait"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="boot">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
<category android:name="android.intent.category.HOME" />
</intent-filter>
</receiver>
<service
android:name="lockservice"
android:process=":lockscreen"
android:icon="@drawable/ic_launcher"
android:label="Lockscreen">
</service>
<activity
android:name=".weather_update"
android:theme="@android:style/Theme.Translucent">
</activity>
</application>
它適用於正常啓動，但在通過服務啓動後，通知欄仍然存在，但無論如何感謝 – user1426956
