橫向模式中警報框出現窗口泄漏錯誤

Question

我已經獲得瞭如下定義的全屏幕縱向活動。

在清單：

<activity 
    android:name=".CameraActivity" 
    android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"> 
</activity> 

和

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 

此活動的OnCreate方法簡單地調用一個警告框，是和否按鈕。我的問題是，當手機保持在橫向狀態時，警報框崩潰，我得到下面顯示的泄漏窗口錯誤。

Answer 1

及其因爲當裝置轉動至LANDSCAPE模式活動將被重新創建。所以它是拋出窗口壞的標誌。

只需在您的清單中添加以下代碼行即可。

android:configChanges="keyboardHidden|orientation"
