RecyclerView Child Item Click in onBindViewHolder()

Issue

I have a RecyclerView and a like button inside of it. For example I want to make a Toast message when I clicked the button. Sample code:

class ViewHolder extends RecyclerView.ViewHolder{

    Button button;

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

    button = itemView.findViewById(R.id.button);

    }
}

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

     holder.button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Toast.makeText(context, ""+list.get(position).getId(), Toast.LENGTH_SHORT).show();
        }
    });

}

So is this way correct ? I'm not sure this must be inside of onBindViewHolder() because of performance issue? So can you tell me is there a better way for child item click event in RecyclerView? By the way these are only example codes. In real I'm dealing more complex things when I clicked the button(request to server).

Solution

You can simply do like this:

class ViewHolder extends RecyclerView.ViewHolder{

Button button;

public ViewHolderMultiple(@NonNull View itemView) {
  super(itemView);

  button = itemView.findViewById(R.id.button);

  button.setOnClickListener(this);
}

@Override
public void onClick(View view) {
   Toast.makeText(context, ""+list.get(getAdapterPosition()).getId(), Toast.LENGTH_SHORT).show();
    }
}
