这是MyActivity的onCreate（我的片段的代码）：

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();

这是getInstance方法在片段类：

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

的问题是，您使用的是相同的片段，每次堆栈中命名您点击这里一个GridView项：

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

你需要做的是设置该字符串为null：

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

，或者如果你正在使用的名字从返回堆栈，然后使用不同的名称为每个GridView的的onclick的
