ProgressDialog只在肖像模式下泄漏窗口錯誤

我正在開發一個應用程序，它會拍攝一張照片並進行一些長時間的處理。在處理期間，我想顯示經由ProgressDialog的狀態，因此我延長的AsyncTask類作爲如下所示ProgressDialog只在肖像模式下泄漏窗口錯誤

以下

private class ResultTask extends AsyncTask<multiCrop, String, String> { 

    @Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 
     progressDialog = new ProgressDialog(MainActivity.this); 
     progressDialog.setTitle("Analyzing, please wait ..."); 
     progressDialog.setMessage("Loading.."); 
     progressDialog.setCancelable(false); 
     progressDialog.show(); 
    } 

    @Override 
    protected String doInBackground(multiCrop... mcImgV) { 
     String result = null; 
     //Long processing that uses view multiCrop and occasional publishProgress() calls, returns String result 
    } 

    @Override 
    protected void onProgressUpdate(String... str) { 
     // TODO Auto-generated method stub 
     super.onProgressUpdate(str); 
     progressDialog.setMessage(str[0]); 
    } 

    @Override 
    protected void onPostExecute(String result) { 
     super.onPostExecute(result); 
     ((TextView)findViewById(R.id.resultText)).append(result); 
     progressDialog.dismiss(); 
    } 

}

的ResultTask一個實例在視圖中的按鈕之一的的onClick處理程序創建的

public void onResultClick(View v){ 
    ResultTask task = new ResultTask(); 
    task.execute(babyImageView); 
}

當設備處於景觀代碼工作沒有任何問題，但如果onResultClick事件在肖像模式觸發我得到一個錯誤，指出MainActivity有LeakedWindow。我在這裏錯過了什麼？

*請注意，即使沒有方向變化時出現錯誤

試試這個

logcat中出現此錯誤 -

protected void onPostExecute(String result) { 
      super.onPostExecute(result); 
    progressDialog.dismiss(); 

    ((TextView)findViewById(R.id.resultText)).append(result);

依然存在的問題仍然存在 – jMathew

第一件事嘗試在UI線程內使用進度對話框。

 public class LoginScreen extends FragmentActivity { 
     ProgressDialog progressDialog; 


     @Override 
     protected void onCreate(Bundle arg0) { 
      // TODO Auto-generated method stub 
      super.onCreate(arg0); 
      requestWindowFeature(Window.FEATURE_NO_TITLE); 

       setContentView(R.layout.activity_login); 
    progressDialog = ProgressDialog.show(
               LoginScreen.this, null, 
               "Logging you in..."); 
             progressDialog.setCancelable(false); 
    } 
public void progressDialogDismiss() { 
     LoginScreen.this.runOnUiThread(new Runnable() { 
      @Override 
      public void run() { 
       if (progressDialog.isShowing()) 
        progressDialog.dismiss(); 
      } 
     }); 
    } 
    }

試着用這樣的。使用它一個工具類。

對不起人，顯然錯誤是在ResultTask實例之前的幾行中，我從位於視圖邊界之外的multiCrop視圖中提取位圖。

感謝您的建議。
