从 ViewHolder 获取 ID

Question

我需要点击一张图片并发送一个 URL（意向），但我有很多图片，所以我试图获取 ID，但我找不到合适的方法来做这件事，如果你们可以帮助我，我尝试了我所知道的一切

public class ProgramAdapter extends RecyclerView.Adapter<ProgramAdapter.ViewHolder> 
{
Context context;
String[] programTituloList;
String[] programDescList;
int[] programImages;

    public static class ViewHolder extends RecyclerView.ViewHolder 
  {
    TextView rowTitulo;
    TextView rowDesc;
    ImageView rowImage;

    public ViewHolder(@NonNull View itemView)
 {
        super(itemView);
        rowTitulo = itemView.findViewById(R.id.txt_titulo);
        rowDesc = itemView.findViewById(R.id.txt_desc);
        rowImage = itemView.findViewById(R.id.imagem_box);
    }
}

public ProgramAdapter(Context context, String[] programTituloList,
                      String[] programDescList, int[] images) {
    this.context = context;
    this.programTituloList = programTituloList;
    this.programDescList = programDescList;
    this.programImages = images;
}

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

    LayoutInflater inflater = LayoutInflater.from(context);
    View view = inflater.inflate(R.layout.box, parent, false);
    ViewHolder viewHolder = new ViewHolder(view);
    return viewHolder;

}

@Override
public int getItemCount() {
    return programTituloList.length;
}

@Override
public void onBindViewHolder(@NonNull ProgramAdapter.ViewHolder holder, int position) {
    holder.rowTitulo.setText(programTituloList[position]);
    holder.rowDesc.setText(programDescList[position]);
    holder.rowImage.setImageResource(programImages[position]);
    
    holder.rowImage.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
           
             if ()
             {
                 Uri uri = Uri.parse("http://www.google.com");
                 Intent i = new Intent(Intent.ACTION_VIEW, uri);
                 context.startActivity(i);
             }
        }
    });
}

} 反正 select 图片名称并做一个 Intet url ??

我只是用这段视频改编了这段代码并成功了

holder.rowImage.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View view)
            {
                Intent intent = new Intent(Intent.ACTION_VIEW);
                intent.setData(Uri.parse(Url[holder.getBindingAdapterPosition()]));
                context.startActivity(intent);
            }
        });
