活動警報之前被關閉解散

在下面給出的代碼我得到，我得到的onProgressUpdate在alert.show異常錯誤「Alertdialog解散前，給予活動窗口泄露異常活動被關閉」。這是什麼解決方案？活動警報之前被關閉解散

我不知道解決的辦法是什麼。當我在對話框打開的情況下退出活動時，我會始終得到它。似乎是無害的，因爲除了日誌中的錯誤之外，它不會對應用程序做任何事情。 – Ixx

一件事，你可以以關閉AlertDialog做，而活動結束，是重寫的onDestroy並關閉它。

@Override 
public void onDestroy(){ 
    try{ 
     alert.dismiss(); 
    } 
    catch(Exception e) {e.printStackTrace();} 
    super.onDestroy() 
}

這不起作用，仍然給出相同的例外。再次 – bkshukla

嘗試不檢查，如果警報！= NULL && alert.isShowing（）。並確定這是你解僱右側的對話框。如果這不應該工作，嘗試onStop（），但不明白爲什麼它不應該在onDestroy（）中工作。 – Carnal

仍然有相同的例外。 – bkshukla
