Click listener in RecyclerView

Question

I had used RecyclerView several times and also handled click listeners. But my question is that in RecyclerView Adapter at which place setting the click listener is better, like in onCreateViewHolder() or onBindViewHolder() or in ViewHolder class. Because, I know at any place we set we can achieve our functionality.

Answer 1

You can set click listener for multiple views in your container view for various purposes. Best approach if it is an item click to add listener to container view :

private final OnClickListener mOnClickListener = new MyOnClickListener();

@Override
public MyViewHolder onCreateViewHolder(final ViewGroup parent, final int position) {
    View view = LayoutInflater.from(mContext).inflate(R.layout.containerViewItem, parent, false);
    view.setOnClickListener(mOnClickListener);
    return new MyViewHolder(view);
}

And implement onClick() method for your mOnClickListener .

Answer 2

The onBindViewHolder method is called every time when you bind your view with data.So the best place is to set click listener inside onCreateViewHolder method.

 private final OnClickListener mOnClickListener = new MyOnClickListener();

 @Override
  public ViewHolder onCreateViewHolder(final ViewGroup parent, final  int position) 
      {
       View view = LayoutInflater.from(mContext).inflate(R.layout.recycler_list_item, parent, false);
       view.setOnClickListener(mOnClickListener);
       return new ViewHolder(view);
     }

 @Override
 public void onClick(final View view) {

      }
