RecyclerView没有LayoutManager Android
我试图使用RecyclerView在片段中显示数据，但它一直显示错误RecyclerView没有LayoutManager 这是我的适配器RecyclerView没有LayoutManager Android,android,android-layout,android-recyclerview,Android,Android Layout,Android Recyclerview,我试图使用RecyclerView在片段中显示数据，但它一直显示错误RecyclerView没有LayoutManager 这是我的适配器 public class FilmAdapter extends RecyclerView.Adapter<FilmAdapter.FilmViewHolder> { private List<Film> mFilmList; private Context context; public Film
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();
}
}
但这仍然是一个错误。有人能帮忙吗？提前感谢mRecyclerview来自哪里？它不是应该是recyclerview吗？通过将适配器更改为
public class FilmAdapter extends RecyclerView.Adapter<FilmAdapter.FilmViewHolder> {
private List<Film> mFilmList;
private Context context;
public FilmAdapter(List <Film> FilmList) {
mFilmList= FilmList;
}
@Override

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();
}
}

mRecyclerView.setLayoutManager（mllayoutmanager） 删除回收器视图内的相对布局。不受其他布局或编辑器输入标记的影响，使用回收器视图不要在回收器视图本身中使用嵌套的子元素，而是使用另一个布局并将其膨胀。参考这个@whenthemorningcomes你是指activityMain中的RecyclerView吗？不，关于片段中的RecyclerView\u now\u playing.xml有什么交易？您在哪里扩展此视图？@Whenthemornings我删除了片段中的RecyclerView，但仍然错误RecyclerView没有布局管理器您可以发布grid\u film.xml文件的代码片段吗？如果可能，请同时发布logcat信息；如果使用recyclerview而不是mRecycleview，会发生什么？
