Android 当试图用其他信息填充活动b时，应用程序不断崩溃

我已经设置了应用程序，因此当我点击回收器视图上的视图时，电影图像会正确过渡到活动B。现在，当我尝试填充活动B中对象的信息（如绘图等）时，我收到一个错误，即onBindViewHolder中的内容为空。我一定是遗漏了什么，因为我之前设置应用程序的方式（一张卡上的所有信息）所有内容都被正确地查询和显示。当我决定更改并将信息发送到活动B时，这一切就开始发生了

这是适配器

public class MoviesAdapter extends RecyclerView.Adapter<MoviesAdapter.MyViewHolder> {

private List<MovieData> moviesList;
private Context context;
private ClickListener clickListener;
ImageLoader imageLoader = AppController.getInstance().getImageLoader();

public MoviesAdapter(Context context, List<MovieData> moviesList) {
    this.moviesList = moviesList;
    this.context = context;
}

public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    public TextView title, plot, releaseDate, rating;
    public ImageView thumb;
    public NetworkImageView moviePic;

    public MyViewHolder(View view) {
        super(view);
        view.setOnClickListener(this);
        title = (TextView) view.findViewById(R.id.name);
        plot = (TextView) view.findViewById(R.id.plot);
        releaseDate = (TextView) view.findViewById(R.id.releaseDate);
        rating = (TextView) view.findViewById(R.id.rating);
        thumb = (ImageView) view.findViewById(R.id.thumb);
        moviePic = (NetworkImageView) view.findViewById(R.id.profilePic);
    }

    @Override
    public void onClick(View v) {

        //context.startActivity(new Intent(context,DisplayActivity.class));
        if (clickListener != null) {
            clickListener.itemClicked(v, getAdapterPosition());

            }
        }
    }


@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.movie_row, parent, false);

    return new MyViewHolder(itemView);
}

@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
    MovieData movie = moviesList.get(position);
   holder.title.setText(movie.getTitle());
    holder.plot.setText(movie.getPlot());
    holder.releaseDate.setText(movie.getReleaseDate());

    holder.rating.setText(movie.getRating());
    Float nRating = Float.parseFloat(holder.rating.getText().toString());

    if (nRating > 6.5) {
        holder.thumb.setImageResource(R.drawable.ic_thumbs_up);
    } else {
        holder.thumb.setImageResource(R.drawable.ic_thumbdown);
    }



    holder.moviePic.setImageUrl(movie.getImage(), imageLoader);

}



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


//Interface and method to help with clicks
public interface ClickListener {

    void itemClicked(View view, int position);
}

public void setClickListener(ClickListener clickListener) {
    this.clickListener = clickListener;
}

}

这是logcat

这里的问题是

MyViewHolder

类和

onBindViewHolder（）

方法引用并调用了不在

movie\u行中的视图上的方法。例如，尝试查找
R.id.plot
，然后在
onBindViewholder（）
中尝试调用
holder.plot.setText（）
。您的
movie\u行中没有id绘图的TextView，因此会出现NullPointerException和崩溃

假设您以前确实在其中包含其他视图，然后在创建第二个活动时将其删除

解决这一问题的两个主要选择是，如果您确实希望在RecyclerView中显示您试图在
movie_row.xml
中引用的所有视图，或者如果它们不在那里，则将它们从
MyViewHolder
类和
onBindViewHolder（）中删除
method.
movie\u行
view holder的XML是什么样子的？@Jose在MoviesAdapter的第78行和第27行。请在此处添加您的电影\u row.xml我将添加代码top@MaharithAdityaSS  updated@LewisMcGeary更新好了，回收器视图只处理活动A上的网格，只有图像…我只希望这些视图膨胀并在活动B上设置？我怎样才能做到这一点？@JoseBurgos看到了我答案的最后一段；如果RecyclerView只显示
NetworkImageView
，那么请转到您的
MyViewHolder
类和
onBindViewHolder（）
方法，删除RecyclerView中不存在的有关thumb和TextView的所有内容。成功了，谢谢
