我的问题是哪一个是更好的方法,请推荐任何其他方法(如果有的话)

1)在ViewHolder中：

public static class ViewHolder extends RecyclerView.ViewHolder {

    public ViewHolder(View itemView) {
        super(itemView);
        tvSrc = (TextView) itemView.findViewById(R.id.tvSrc);
        itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(v.getContext(),"inside viewholder position = " + getAdapterPosition(),Toast.LENGTH_SHORT).show();
            }
        });
    }

2)在BindViewHolder中

public void onBindViewHolder(DisplayTrainsAdapter.ViewHolder viewHolder,final int position) {

    viewHolder.tvSrc.setText(mDataset.get(position).strSrc);
    viewHolder.tvSrc.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Toast.makeText(v.getContext(),"position = " + getItemId(position),Toast.LENGTH_SHORT).show();
        }
    });
}
