關於旋轉android應用程序崩潰

Question

我有一個應用程序在縱向和橫向使用兩個佈局。要在初始加載時從web加載內容，我使用AsyncTask和進度條。

我檢查了this。由於我有兩個佈局，這不是解決方案。

下面給出例外。

有沒有辦法鎖定旋轉變化，直到應用程序加載它自己？

還是其他的想法？

在此先感謝。

Answer 1

我在onDestroy()方法中調用了progressDialog.dismiss()。

在方向更改期間，活動重新啓動。所以在重新啓動之前，我們必須銷燬當前的progressDialog。這是訣竅。 ：D

Answer 2

您會得到WindowLeak異常，當任何對話框/ progressBar使用由於方向更改而丟失的上下文引用和上下文引用時，會發生此異常。

因此，下面的代碼清單文件中的所有活動標籤。

android:configChanges="orientation|keyboard" 

例如：

<activity 
      android:name=".InviteActivity" android:configChanges="orientation|keyboard"/> 

，並在活動中使用下面的代碼

@Override 
    public void onConfigurationChanged(Configuration newConfig) 
    { 
     setContentView(R.layout.YOUR_LAYOUT); 
     super.onConfigurationChanged(newConfig); 
    } 

Answer 3

我有同樣的問題，解決它的方式，我開始同步之前鎖定的方位和設置同步後返回：

// before 
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR); 

// after synchronisation: 
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR); 

Answer 4

當您切換方向時，Android會創建一個新的視圖。你可能會因爲後臺線程試圖改變舊版本的狀態而崩潰。 （它可能也有麻煩，因爲你的後臺線程不在UI線程上）。 這些都是解決方案：
