RecyclerView沒有佈局管理的Android

-1

我想使用的分段數據RecyclerView但它繼續顯示錯誤RecyclerView沒有佈局管理RecyclerView沒有佈局管理的Android

這裏是我的適配器

public class FilmAdapter extends RecyclerView.Adapter<FilmAdapter.FilmViewHolder> { 

    private List<Film> mFilmList; 
    private Context context; 

    public FilmAdapter(List <Film> FilmList) { 
      mFilmList= FilmList; 
    } 


    public static class FilmViewHolder extends RecyclerView.ViewHolder { 
     ImageView foto; 

     public FilmViewHolder(View v) { 
      super(v); 
      foto = (ImageView) v.findViewById(R.id.posterFilm); 
     } 
    } 

    @Override 
    public FilmAdapter.FilmViewHolder onCreateViewHolder(ViewGroup parent,int viewType) { 
     View mView = LayoutInflater.from(parent.getContext()).inflate(R.layout.grid_film, parent, false); 
     FilmAdapter.FilmViewHolder mViewHolder = new FilmAdapter.FilmViewHolder(mView); 
     return mViewHolder; 
    } 

    @Override 
    public void onBindViewHolder(FilmViewHolder holder, int position) { 
     Picasso.with(context).load("http://ecinema.esy.es/img/" + mFilmList.get(position).getBackdropPath()).resize(200, 250).into(holder.foto); 
    } 

    @Override 
    public int getItemCount() { 
     return mFilmList.size(); 
    } 
}

片段

public class NowPlayingFragment extends Fragment implements RecyclerItemClickListener.OnItemClickListener{ 
    ApiInterface mApiInterface; 
    private RecyclerView mRecyclerView; 
    private RecyclerView.Adapter mAdapter; 
    private RecyclerView.LayoutManager mLayoutManager;

         String.valueOf(movies.size()));

我嘗試搜索錯誤，他們說加

mRecyclerView.setHasFixedSize(true);

但它仍然錯誤。任何人都可以幫忙嗎？在此先感謝

不要在RecyclerView本身中使用嵌套的子元素，而要使用另一個佈局並使其膨脹。參考這[後]（http://stackoverflow.com/questions/33969443/why-is-it-saying-recyclerview-has-no-layoutmanager-when-there-is-one-please-s） –

@whenthemorningcomes你的意思是RecyclerView in activityMain？ –

不，關於RecyclerView裏面fragment_now_playing.xml的處理是什麼？你在哪裏誇大這個觀點？ –

mRecyclerview從哪裏來？是不是應該是recyclerview？

private RecyclerView mRecyclerView; –

如果使用recyclerview而不是mRecycleview，會發生什麼情況？ – Mabz

通過改變適配器

public class FilmAdapter extends RecyclerView.Adapter<FilmAdapter.FilmViewHolder> { 

    private List<Film> mFilmList; 
    private Context context; 

    public FilmAdapter(List <Film> FilmList) { 
      mFilmList= FilmList; 
    } 

    @Override 
    public FilmViewHolder onCreateViewHolder(ViewGroup parent,int viewType) { 
     View mView = LayoutInflater.from(parent.getContext()).inflate(R.layout.grid_film, parent, false); 
     FilmViewHolder mViewHolder = new FilmViewHolder(mView); 
     return mViewHolder; 
    } 

    @Override 
    public void onBindViewHolder(FilmViewHolder holder, int position) { 
     Picasso.with(context).load("http://ecinema.esy.es/img/" + mFilmList.get(position).getBackdropPath()).resize(200, 250).into(holder.foto); 
    } 

    public static class FilmViewHolder extends RecyclerView.ViewHolder { 
     public ImageView foto; 

     public FilmViewHolder(View v) { 
      super(v); 
      foto = (ImageView) v.findViewById(R.id.posterFilm); 
     } 
    } 

    @Override 
    public int getItemCount() { 
     return mFilmList.size(); 
    } 
}

和碎片解決錯誤

public class NowPlayingFragment extends Fragment implements RecyclerItemClickListener.OnItemClickListener{ 
    ApiInterface mApiInterface; 
    private RecyclerView mRecyclerView; 
    private RecyclerView.Adapter mAdapter; 
    private RecyclerView.LayoutManager mLayoutManager; 
    public static MainActivity m; 
    String idKota = m.getIdKota(); 

    @Nullable 
    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 

     View v = inflater.inflate(R.layout.fragment_now_playing, container, false); 

     mRecyclerView = (RecyclerView) v.findViewById(R.id.rootLayout); 
     mLayoutManager = new LinearLayoutManager(this.getActivity()); 
     mRecyclerView.setLayoutManager(mLayoutManager); 
     mRecyclerView.setHasFixedSize(true); 
     mApiInterface = ApiClient.getClient().create(ApiInterface.class); 
     mAdapter = new FilmAdapter(new ArrayList<Film>()); 
     mRecyclerView.setAdapter(mAdapter); 
     refresh(); 

     return v; 
    } 

    public void refresh() { 
     Call<List<Film>> call = mApiInterface.getFilmPlaying(
       idKota 
     ); 
     call.enqueue(new Callback<List<Film>>() { 
      @Override 
      public void onResponse(Call<List<Film>> call, Response<List<Film>> response) { 
       List<Film> FilmList = response.body(); 
       Log.d("Retrofit Get", "Jumlah data : " + 
         String.valueOf(FilmList.size())); 
       mAdapter = new FilmAdapter(FilmList); 
       mRecyclerView.setAdapter(mAdapter); 
      } 

      @Override 
      public void onFailure(Call<List<Film>>call, Throwable t) { 
       Log.e("Retrofit Get", t.toString()); 
      } 
     }); 

     //mRecyclerView.addOnItemTouchListener(new RecyclerItemClickListener(getActivity(), this)); 
    } 

    @Override 
    public void onItemClick(View childView, int position) { 

    } 

    @Override
