将主屏幕时，重复的动作在Android应用程序

简介：
我的客户需要在整个应用程序的一些组件，如navigationDrawer，toolbar。所以我有一个MainActivity有两个toolbar（顶部/底部）和两个导航抽屉（左/右）。所有其他屏幕包含fragments，我在MainActivity更改。我有一个小问题，就是一些动作被重复。
案例：在一些fragments当用户执行一个动作即
1：用户按下“放入购物车” button，按家庭button是在toolbar底部的“添加到购物车” button运行代码两次（一旦点击按钮，一旦进入主屏幕），所以我的物品被添加到购物车两次。
2：在另一个片段我有“申请优惠券” checkbox当用户检查checkbox的AlertDialog出现，当用户进入主屏幕AlertDialog再次出现在主屏幕。将主屏幕时，重复的动作在Android应用程序

我只是重新创建回家按钮按下的主要活动与recreate();

我检查的代码，但不明白为什么这些动作重复。如果有人遇到相同或类似的问题，请指导我如何解决这个问题。任何帮助，将不胜感激。

如果我需要显示代码告诉我哪个部分？

编辑：内的片段车详细onCreateView

useCoupon.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
      @Override 
      public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
       if (isChecked) { 
        createAndShowCustomAlertDialog(); 
       } 
      } 
     });

序列这个代码是主要活动（主碎片）=>产品分片=>车详细破片。
