屏幕上的應用程序崩潰旋轉

我正在線程中實現進度對話框。它可以在橫向或縱向模式下正常工作。但是，當設備旋轉的應用程序崩潰，並給出以下異常：屏幕上的應用程序崩潰旋轉

我androidMainfest.xml

<activity 
     android:name="and.androidrest.Myactivity" 
     android:label="@string/app_name" 
     android:launchMode="standard" >

我的活動代碼：

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_sax_parser); 
    callDialog(); 
} 
public void callDialog(){ 
    progressDialog = new ProgressDialog(this); 
    progressDialog.setTitle("Please wait.."); 
    progressDialog.setCancelable(false); 
    progressDialog.setMessage("Loading..."); 
    progressDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); 
    progressDialog.show(); 


    new Thread(new Runnable(){ 
     public void run(){ 
      try{ 
       Thread.sleep(2000);   
      } 
      catch (Exception e){ 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 

      if(progressDialog != null){ 
       try{ 
        progressDialog.dismiss(); 
        progressDialog=null; 
       } 
       catch(Exception e) { 
        e.printStackTrace(); 
       }   
      }    
     } 
    }).start();  
}

這裏是我的logcat：

是非常有用的張貼logcat的也 – nikis

'android：configChanges =「orientation | screenLayout' - 除非你真的**明白爲什麼這是一個黑客行爲，爲什麼你不應該這樣做，你應該閱讀活動生命週期文檔以及如何以及何時使用onResume（），onPause（），onStop（）和其他生命週期方法，如果你不明白，那麼你所要做的就是隱藏錯誤，因爲你沒有正確使用這些方法。 – Simon

您在活動中使用進度dailog。所以，當你旋轉手機，那麼它會拋出異常leakwindow。對於您需要dissmiss在旋轉時間進度......

使用，這將解決您的問題

@Override 
public void onPause() 
{ 
    super.onPause(); 

    if(progressDialog != null) 
    { 
     progressDialog.dismiss(); 
    } 

}
