Alertdialog解散之前活動關閉，並給出活動泄露窗口例外

2012-08-13 109 views

在onPostExecute我試圖顯示處理程序，但它給予異常活動已泄漏窗口。錯誤點在代碼中突出顯示如下。這個問題的解決方案是什麼？Alertdialog解散之前活動關閉，並給出活動泄露窗口例外

的AsyncTask doInBackground（ Params ...）涉及非UI線程來執行任務，因此調用UI執行將產生異常。在你的情況下，你需要去http://developer.android.com/reference/android/os/AsyncTask.html#onProgressUpdate（Progress ...） – 2012-08-13 14:00:28

你在doinbackground中做了太多的ui操作，你不應該從這個線程顯示提示對話框 – nandeesh 2012-08-13 14:04:29

當您在活動有效完成後嘗試顯示警報時，會發生「活動泄漏了最初添加的窗口...」錯誤。見Activity has leaked window that was originally added。

你有AFAIK兩種選擇：

  1. 重新考慮你的警戒登錄：實際上退出您的活動之前調用解僱（）在對話框上。
  2. 將對話框放入其他線程並在該線程上運行（與當前活動無關）。

我已經嘗試了第一點，但它不工作，而它給出了同樣的錯誤。請你詳細說明第二點？ – bkshukla 2012-08-13 14:27:07

對於第二個建議，您可以嘗試使用Runnable在新線程上顯示警報。 runOnUiThread（new Runnable（）{ public void run（）{MyDialog.Prompt（NameOfYourActivity.this）;} }）; – 2012-08-13 14:32:46

嘗試使用DialogFragment，而不僅僅是一個對話框。他們更好地處理生命週期。

好吧，讓我給一些基本思想，以顯示對話框同時更新，

class Communicator extends AsyncTask<String, Integer, String> 
{ 
    int prog = 0; 

    @Override 
    protected String doInBackground(String... params) { 
     String response = null; 
     try { 
      if(Login.uname != null && Login.pass != null){ 
      sync(Login.uname, Login.pass); 
      }else if(SplashScreen.user != null && SplashScreen.pas != null){ 
       sync(SplashScreen.user, SplashScreen.pas); 
      } 
      if("ok".equalsIgnoreCase(status)) 
      { 
       if(memoryInfo(true)){ 
        publishProgress(LOW_MEMORY); 
        return (null); 
       }else{.....

用於顯示對話框

protected void onProgressUpdate(Integer... statusCode) { 
    switch (statusCode[0]) { 
    case LOW_MEMORY: 
     AlertDialog alert =new AlertDialog.Builder(NeliteMusicActivity.this).create(); 
     alert.setTitle(R.string.set4Play); 
     alert.setMessage(getString(R.string.lowMemorySync)); 
     alert.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND); 
     alert.setButton(getString(R.string.ok), new DialogInterface.OnClickListener() { 
      @Override 
      public void onClick(DialogInterface dialog, int which) { 
       alert.dismiss(); 
      } 
     }); 
     alert.setCanceledOnTouchOutside(false); 
     alert.show(); 
     break; 
    } 
}

希望這將使意義
