如何从android中的recyclerView中删除项目

在我的应用程序中，我应该使用 recyclerView 并删除一些项目。
我想从中删除一些项目recyclerview为此，我在以下代码中编写Adapter :

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

    private Context context;
    private List<TvTonightResult> model;

    public MyAdapter (Context context, List<TvTonightResult> model) {
        this.context = context;
        this.model = model;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.row_tv_tonight, parent, false);

        return new ViewHolder(view);
    }

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

        holder.tvTonightTitle.setText(Html.fromHtml(model.get(position).getName()));
        Glide.with(context)
                .load(model.get(position).getImageUrl())
                .placeholder(R.drawable.default_image)
                .override(600, 900)
                .diskCacheStrategy(DiskCacheStrategy.ALL)
                .listener(new RequestListener<String, GlideDrawable>() {
                    @Override
                    public boolean onException(Exception e, String model, Target<GlideDrawable> target, boolean isFirstResource) {
                        return false;
                    }

                    @Override
                    public boolean onResourceReady(GlideDrawable resource, String model,
                                                   Target<GlideDrawable> target, boolean isFromMemoryCache, boolean isFirstResource) {
                        return false;
                    }
                })
                .into(holder.tvTonightImage);

        long time = 5 * 1000;
        holder.tvTonightTimeCounter.start(time);
        holder.tvTonightTimeCounter.setOnCountdownEndListener(new CountdownView.OnCountdownEndListener() {
            @Override
            public void onEnd(CountdownView cv) {
                removeItem(position);
            }
        });
    }

    @Override
    public int getItemCount() {
        return 4;
    }

    public class ViewHolder extends RecyclerView.ViewHolder {

        private ImageView tvTonightImage, tvTonightChannel;
        private TextView tvTonightTitle, tvTonightDate;
        private CountdownView tvTonightTimeCounter;

        public ViewHolder(View itemView) {
            super(itemView);

            tvTonightImage = (ImageView) itemView.findViewById(R.id.row_tvTonightImage);
            tvTonightChannel = (ImageView) itemView.findViewById(R.id.row_tvTonightChannelImage);
            tvTonightTitle = (TextView) itemView.findViewById(R.id.row_tvTonightTitle);
            tvTonightTimeCounter = (CountdownView) itemView.findViewById(R.id.row_tvTonightTime);

        }
    }

    private void removeItem(int position) {
        model.remove(position);
        notifyItemRemoved(position);
        notifyItemRangeChanged(position, model.size());
    }
}

我想当运行这段代码时，remove物品 ：

holder.tvTonightTimeCounter.setOnCountdownEndListener(new CountdownView.OnCountdownEndListener() {
                @Override
                public void onEnd(CountdownView cv) {
                    removeItem(position);
                }
            });

但给我看看这个error :

我该如何修复此错误并从中删除项目recyclerview?

你试一试 ，

int actualPosition = holder.getAdapterPosition();

in your removeItem()方法并将位置替换为actualPosition.

like ,

  private void removeItem(int position) {
    int actualPosition = holder.getAdapterPosition();
    model.remove(actualPosition);
    notifyItemRemoved(actualPosition);
    notifyItemRangeChanged(actualPosition, model.size());
}
