android.view.WindowLeaked - 同時使用對話框和新的意圖

Question

我已經嘗試了所有可能的解決方案提供在stackoverflow。但我仍然坐在這個錯誤logcat：

'Activity com.xyz.MainActivity has leaked window com.android.internal.policy.impl.PhoneWindow $ DecorView {40d687c0 VE .... R ... ..ID 0,0-772,268}，最初這裏加入」

    if (Var_place_holder.level == "one") 
        { 
         Var_place_holder.title=obj_itemDetails.getTitle(); 
         Var_place_holder.level="two"; 
         Intent intent = getIntent(); 
         dialog.dismiss(); 
         finish(); 
         startActivity(intent);} 

       if (Var_place_holder.level == "two") 
        { 
        AlertDialog.Builder alert = new AlertDialog.Builder(MainActivity.this); 

        String Category = Var_place_holder.title; 
        //String IMGURL = obj_itemDetails.getIcon(); 
        String Desc = obj_itemDetails.getTitle(); 

        alert.setTitle("Detail:"); 
        String Msg1 = "Category: " + Category; 
        String Msg2 = "Desc: " + Desc; 
        alert.setMessage(Msg1+"\n"+Msg2+"\n"); 

        //alert.setMessage("Price: Rs." + Price); 
        alert.setPositiveButton("Add", new DialogInterface.OnClickListener() { 
          public void onClick(DialogInterface dialog, int whichButton) { 
        //************************************** 
        //Do something -- TBD 
        //************************************** 
          dialog.cancel(); 

          } 
         }); 

        alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
          public void onClick(DialogInterface dialog, int whichButton) { 
        //************************************** 
        //Do something -- TBD 
        //************************************** 
          dialog.cancel(); 

           } 
          });       
        AlertDialog alertDialog = alert.create(); 
        alertDialog.show(); 

       } 

下面是我得到的logcat錯誤：

此外，如何嚴重的是這個錯誤？儘管在logcat中出現此錯誤，該應用似乎仍能正常工作。

Answer 1

不要忘記在第一種情況下返回操作？

if (Var_place_holder.level.equals("one")) { 
     Var_place_holder.title=obj_itemDetails.getTitle(); 
     Var_place_holder.level="two"; 
     Intent intent = getIntent(); 
     dialog.dismiss(); 
     finish(); 
     startActivity(intent); 
     return; 
} 

現在你想開始新的活動（並停止當前的），之後就是準備連接到第一已經停止活動ANS顯示對話框。
