我试图使用RecyclerVIewAdapter和毕加索将图像添加到RecyclerView中

Question

我试图做到这一点，但我没有运气，图像不显示在屏幕上 我很新，所以这里是我的代码

我RecyclerViewAdapter：

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> { 

    public Context context; 
    public ArrayList<MoviesData> array; 
    public LayoutInflater inflater; 


    RecyclerViewAdapter(Context context,ArrayList<MoviesData> array) 
    { 
     this.context = context; 
     this.array = array; 
     this.inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    } 



    public class ViewHolder extends RecyclerView.ViewHolder { 

     ImageView image; 


     public ViewHolder(View itemView) { 
      super(itemView); 
      image = (ImageView) itemView.findViewById(R.id.oneMovieBlockImageView); 
     } 


    } 

    @Override 
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 

     View rootview = inflater.inflate(R.layout.movie_block,parent,false); 

     ViewHolder viewHolder = new ViewHolder(rootview); 

     return viewHolder; 
    } 

    @Override 
    public void onBindViewHolder(ViewHolder holder, int position) { 


     //holder.image.setImageResource(Picasso.with(context).load(array.get(position).getPoster_path()).into(image)); 
     MoviesData current = array.get(position); 
     Picasso.with(context).load(current.getPoster_path()).into(holder.image); 


    } 

    @Override 
    public int getItemCount() { 
     return 0; 
    } 
} 

我的LinearLayout它具有RecyclerView

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="com.example.android.themovieapp.MainActivityFragment" 
    > 


    <android.support.v7.widget.RecyclerView 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:id="@+id/recyclerview" 
     > 


    </android.support.v7.widget.RecyclerView> 

</LinearLayout> 

我的ImageView

<ImageView 

    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:scaleType="centerCrop" 
    android:id="@+id/oneMovieBlockImageView" 
    android:adjustViewBounds="true" 

    > 
</ImageView> 

onCreateView方法

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


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


    RecyclerView recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerview); 
    adapter = new RecyclerViewAdapter(getActivity(),moviesDatas); 
    recyclerView.setAdapter(adapter); 
    recyclerView.setLayoutManager(new LinearLayoutManager(getActivity())); 


    return rootView; 

} 

Answer 1

您的适配器是空

@Override 
public int getItemCount() { 
    return 0; 
}} 

请更新到return array.size();
