How do I get the position selected in a RecyclerView?

Solution 1:

Set your onClickListeners on onBindViewHolder() and you can access the position from there. If you set them in your ViewHolder you won't know what position was clicked unless you also pass the position into the ViewHolder

EDIT

As pskink pointed out ViewHolder has a getPosition() so the way you were originally doing it was correct.

When the view is clicked you can use getPosition() in your ViewHolder and it returns the position

Update

getPosition() is now deprecated and replaced with getAdapterPosition()

Update 2020

getAdapterPosition() is now deprecated and replaced with getAbsoluteAdapterPosition() or getBindingAdapterPosition()

Kotlin code:

override fun onBindViewHolder(holder: MyHolder, position: Int) {
        // - get element from your dataset at this position
        val item = myDataset.get(holder.absoluteAdapterPosition)
    }

Solution 2:

A different method - using setTag() and getTag() methods of the View class.

1. use setTag() in the onBindViewHolder method of your adapter

   @Override
   public void onBindViewHolder(myViewHolder viewHolder, int position) {
       viewHolder.mCardView.setTag(position);
   }
   

   where mCardView is defined in the myViewHolder class

   private class myViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
              public View mCardView;
   
              public myViewHolder(View view) {
                  super(view);
                  mCardView = (CardView) view.findViewById(R.id.card_view);
   
                  mCardView.setOnClickListener(this);
              }
          }
   

2. use getTag() in your OnClickListener implementation

   @Override
   public void onClick(View view) {
       int position = (int) view.getTag();           
   
   //display toast with position of cardview in recyclerview list upon click
   Toast.makeText(view.getContext(),Integer.toString(position),Toast.LENGTH_SHORT).show();
   }
