android - Why does OnClickListener on a ViewHolder don't work?

Question

I'm trying to implement a way to handle item selection on a RecyclerView. I personally don't like the way suggested in some answers on SO of passing through gestures, and I thought that implementing an OnClickListener, as suggested here and here, was waaay cleaner.

The fact is that... this pattern doesn't actually work! I'm really not able to understand why my OnClickListener.onClick is never called. It's kinda like another method intercepts the click before onClick can take care of it.

This is my code:

    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        TextView tvName;
        ImageView star;

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

            tvName = (TextView) itemView.findViewById(R.id.CHAT_ITEM_name);
            star = (ImageView) itemView.findViewById(R.id.CHAT_ITEM_star);

            Fonts.setTypeface(tvName, regular);
        }

        @Override
        public void onClick(View view) {
            int position = getLayoutPosition();
            select(position);
        }
    }

Unfortunately it's very important for me to able to access the position of the clicked item in the whole dataset, in order to remove it, so doing something like indexOfChild isn't acceptable too: I tried, but this method gives you the position of the item in the visibile part of the list, thus making list.remove(position) impossible.

Answer 1

Looking at the updated code: you are not setting the onClickListener to any of the views in the ViewHolder. It is an understandable mistake to forget the click listener.

Just use:

tvName.setOnClickListener(this);
star.setOnClickListener(this);

You can set to both or just one of them. You can also simply get the parent layout of these two views, so that the whole item itself in the adapter can be clickable.

itemView.setOnClickListener(this);
