在Android中有對話框和wevView的泄漏窗口

從接收活動對象的引用的Java類處理多個webviews時，我的代碼中存在一個錯誤。在Android中有對話框和wevView的泄漏窗口

這是我的代碼：

try { 
      mActivity.runOnUiThread(new Runnable() { 
       @SuppressLint("NewApi") 
       public void run() { 

        if (webView == null) 
         return; 

        if (visibility) { 
         webView.setVisibility(View.VISIBLE); 
         webView.requestFocus(); 

         if (dialog != null && !dialog.isShowing()) { 
          System.out.println("case1: " + dialog + " , activity: " + mActivity + ", mview " + webView); 

         } else { 
          dialog = WebViewUtils.showWebView(mActivity, webView); 
          System.out.println("case2 " + dialog + " , activity: " + mActivity + ", mview " + webView); 
         } 
         if (!mActivity.isFinishing()) { 
          dialog.show(); 
         } 
        } else { 
         dialog.dismiss(); 
         webView.setVisibility(View.GONE); 
        } 
       } 
      }); 
     } catch (Exception e) { 
      System.out.println(System.out); 
      Log.d(Constants.TAG, e.getMessage()); 
     }

這是錯誤堆棧：

被指出存在的線是我張貼的代碼塊中。如果我檢查活動是否爲空或者對話框是否爲空，那麼不應該讓代碼不要中斷嗎？我搞不清楚了。任何想法都歡迎。謝謝。

你關閉你的對話，如果它已經打開時'onDestroy'被稱爲？你應該控制方向的改變，最近發生在我身上 – zozelfelfo 2014-09-22 11:28:09

我的Java類中沒有onDestroy（）方法，不幸的是:(我正在處理來自非活動類的這些方法，只有Activity對象的引用 – user1140656 2014-09-22 11:32:40

@ user1140656剛剛在退出活動時添加dialog.dismiss（）... – Umair 2014-09-22 11:37:11

就叫dialog.dismiss()，它會很好地工作.... :)
