RecyclerView onclick

RecyclerView step 3

step1
public class xxxxxxxx extends RecyclerView.Adapter<MyAdapter.ViewHolder> implements View.OnClickListener {

step2

public void onBindViewHolder(RecyclerView.ViewHolder viewHolder, int position
viewHolder.textView.setOnClickListener(this);

textView is findViewById(R.id.xxxxxxxxx)

step3

@Override
public void onClick(View view) {
  int viewId = view.getId();
   if (viewId == R.id.xxxxxxxxx) {  //which item click
      if (onItemClickListener != null) {
         onItemClickListener.onItemClick(view, (Integer) view.getTag());
      }
  }
}

view.getTag() maybe null
