OnLongItemClick in RecyclerView

Question

I am starting to use RecyclerView in Android. Things work fine until I implement touch listener for my adapter.

You can add listeners in your custom adapter implementation. It will be something like:

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {

    public interface OnItemClickListener {
        public void onItemClicked(int position);
    }

    public interface OnItemLongClickListener {
        public boolean onItemLongClicked(int position);
    }

    private Fragment mFragment;

    public static class ViewHolder extends RecyclerView.ViewHolder {
        public View v;

        public ViewHolder(View v) {
            super(v);
            this.v = v;
        }
    }

    public RecyclerViewAdapter(Fragment fragment) {
        mFragment = fragment;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, final int position) {
        holder.v.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mFragment.onItemClicked(position);
            }
        });
        holder.v.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                mFragment.onItemLongClicked(position);
                return true;
            }
        });
    }
    . . .
}

Note interfaces definition at the beginning. This way you're passing onClick and onLongClick events to your fragment for handling. Pretty much convenient, you know
