在使用getBindingAdapterPosition时，需要注意它只能在ViewHolder绑定数据之后才能正确返回位置信息。因此，在调用getBindingAdapterPosition之前，需要确保ViewHolder已经绑定了相应的数据。

示例代码：

public class MyAdapter extends RecyclerView.Adapter {

@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    // create a new view
    View v = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.my_layout, parent, false);

    MyViewHolder vh = new MyViewHolder(v);
    return vh;
}

@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
    // bind data to ViewHolder
    holder.bindData(position);
}

public static class MyViewHolder extends RecyclerView.ViewHolder {
    private TextView tv;

    public MyViewHolder(View itemView) {
        super(itemView);
        tv = itemView.findViewById(R.id.tv);
    }

    public void bindData(int position) {
        // set data to views
        tv.setText("Item " + position);
    }
}

public void onItemClick() {
    // get adapter position
    int position = myViewHolder.getBindingAdapterPosition();
    if(position != RecyclerView.NO_POSITION) {
        // do something with position
        Log.d("TAG", "Clicked item at position " + position);
    }
}

}
