在片段添加GridView控件

這裏是我得到的GridView代碼：在片段添加GridView控件

public class MoviesFragment extends Fragment { 


AppController instance = AppController.getInstance(); 
List<Movie> movies = new ArrayList<Movie>(); 
String html; 
@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 

    View rootView = inflater.inflate(R.layout.fragment_movies, container, false); 

    GridView gridView; 
     gridView = (GridView) rootView.findViewById(R.layout.fragment_movies); 
     movies = getMoviesList(); 
     gridView.setAdapter(new MoviesAdapter(getActivity(), movies)); 

    return rootView; 
} 

public List<Movie> getMoviesList() 
{ 
    List<Movie> movies = new ArrayList<Movie>(); 

    try { 
     org.jsoup.nodes.Document doc = Jsoup.parse(getActivity().getAssets().open("site.html"), "UTF-8", ""); 
     Elements get = doc.select("div.post.lit > h2"); 
     for (Element element : get) 
     { 
      movies.add(new Movie(element.text())); 
     } 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
    } 

    System.out.println(movies.size()); 

    return movies; 
} 


}

，這裏是我的MovieAdapter類項目中的GridView：

public class MoviesAdapter extends ArrayAdapter<Movie> 
{ 


List<Movie> moviesList; 
Context context; 

public MoviesAdapter(Context context, List<Movie> objects) 
{ 
    super(context, android.R.id.content, objects); 
    this.moviesList = objects; 
    this.context = context; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) 
{ 
    LayoutInflater layoutInflater = (LayoutInflater)context.getSystemService(context.LAYOUT_INFLATER_SERVICE); 
    View view = layoutInflater.inflate(R.layout.fragment_movies_individual, parent); 
    TextView name = (TextView) view.findViewById(R.id.textView1); 
    TextView description = (TextView) view.findViewById(R.id.textView2); 
    name.setText(moviesList.get(position).getName()); 
    description.setText(moviesList.get(position).getDescription()); 
    return view; 
} 
}

當我運行的應用程序，它只是保持崩潰並將NullPointerException扔在gridView的設置適配器的行中（gridView.setAdapter(new MoviesAdapter(getActivity(), movies)); 我檢查了movieList項目並且它正確地填充了）

這裏有什麼問題？

的錯誤是在這裏：

gridView = (GridView) rootView.findViewById(R.layout.fragment_movies);

您需要提供電網的id作爲findViewById(int)參數。現在你提供了佈局的ID，這顯然是錯誤的。
