這是MyActivity的onCreate（我的片段的代碼）：

Fragment myFragment = MyFragment.getInstance(); 
       Bundle profileArgs = new Bundle(); 
       profileArgs.putSerializable("data", customObject); 
       myFragment.setArguments(profileArgs); 

       FragmentManager manager = getSupportFragmentManager(); 

       FragmentTransaction transaction = manager.beginTransaction(); 

       transaction.add(R.id.fragment_info, myFragment, 
          "MyFragment"); 
       transaction.commit();

這是getInstance方法在片段類：

public static MyFramgent getInstance() { 
         return new MyFramgent(); 
       }

的問題是，您使用的是相同的片段，每次堆棧中命名您點擊這裏一個GridView項：

transaction.add(R.id.fragment_info, myFragment, "MyFragment");

你需要做的是設置該字符串爲null：

transaction.add(R.id.fragment_info, myFragment, null);

，或者如果你正在使用的名字從返回堆棧，然後使用不同的名稱爲每個GridView的的onclick的
