如何在RecyclerView适配器中获取getRef（）？

Question

This is the code I tried:

@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
    // - get element from your dataset at this position
    // - replace the contents of the view with that element
    ChatMessage msg = mMessagesList.get(position);
    holder.messageTextView.setText(msg.getMessage());

    String key = getRef(position).getKey();


    holder.layout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
        }
    });

}

But the getRef() is red and doesn't work. I think it should be inside a populateViewHolder and I don't know how to create one.

Answer 1

From the documentation it looks like method doesn't accept parameters.

getRef()

Used to obtain a reference to the source location for this snapshot.

you can use below code in onBindViewHolder()

String _key=mMessagesList.get(position).getKey();
