java.lang.IllegalArgumentException：找不到id的视图0x7f0c0098

Question

我有一个NBA球队列表，它工作正常，并正确填写球队列表，但是当我点击列表中的一个项目时，它应该使另一个片段用于显示团队选择的描述，但当我点击无法找到fragment_descriptions ID。我使用两个List Fragment一个用于Teams，另一个用于Players，为此我使用ViewPager和一个Placeholder Fragment（由Android Studio自动生成），我认为这是因为布局时fragment_description没有膨胀：/

例外：

       // ejecuta o no 

       if (savedInstanceState != null)

       list.setArguments(it.getExtras()); 

       // Con FragmentManager podremos interactuar entre el fragment_movil y la clase list 
       // gracias a esto pondremos todos las propiedades preparada de ese

       getActivity().getSupportFragmentManager().beginTransaction().add(R.id.fragment_team_movil, list) 
         .commit(); 
      }

谢谢:)我一直用错误整天:(

我刚刚看了一下该项目在GitHub上，我认为你应该更换此行

transaction.replace(R.id.fragment_descriptions, newDescriptionFragment);

这一个

transaction.replace(R.id.fragment_team_movil, newDescriptionFragment);
在MainActivity.java


MainActivity - line 209
