我试图将上下文从java类发送到 RecyclerView ，这样我就可以单击元素并重定向到意图。显然，上下文不对。我已经评论了它的台词，应用程序也可以运行，但只要我试图证明它，它就会再次崩溃。我假设这是一个上下文的东西，但是如果有另一种方法来为我的元素设置click方法的话，它将非常有用。
它引发的异常为空指针异常：
java.lang.runtimeexception:无法启动活动：java.lang.nullpointerexception:尝试对空对象引用调用虚拟方法“void android.widget.button.setonclicklistener（android.view.view$onclicklistener）”
以下是适配器代码：

public class SubsidioAdapter extends RecyclerView.Adapter<SubsidioAdapter.SubsidioViewHolder> {

    private Context context;
    private List<Producto> productoList;
    private LayoutInflater inflater;

    public SubsidioAdapter(Context context, List<Producto> productoList) {
        this.context = context;
        this.productoList = productoList;
        this.inflater = LayoutInflater.from(context);
    }

    @Override
    public SubsidioViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
        View view = this.inflater.inflate(R.layout.producto_item, null);
        return new SubsidioViewHolder(view);
    }

    @Override
    public void onBindViewHolder(SubsidioViewHolder subsidioViewHolder, int position) {
        subsidioViewHolder.imageView.setImageResource(this.productoList.get(position).getFoto());
        subsidioViewHolder.textView1.setText(this.productoList.get(position).getNombre());
        subsidioViewHolder.textView2.setText(this.productoList.get(position).getDescripcion());
        subsidioViewHolder.textView3.setText(this.productoList.get(position).getPrecio());
        subsidioViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                context.startActivity(new
                        Intent(context, ModificarProductoActivity.class));
            }
        });
    }

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

    public class SubsidioViewHolder extends RecyclerView.ViewHolder {

        ImageView imageView;
        TextView textView1;
        TextView textView2;
        TextView textView3;

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

            this.imageView = itemView.findViewById(R.id.fotoSub);
            this.textView1 = itemView.findViewById(R.id.descSub);
            this.textView2 = itemView.findViewById(R.id.nombreSub);
            this.textView3 = itemView.findViewById(R.id.precioSub);

        }
    }
}
