Question

Here is the code I used in my RecycleView adapter class. I don\'t know this is the right way or not to use View Binding. If you have a better solution answer me. Th

Answer 1

What you need to do is pass the generated binding class object to the holder class constructor. In your example, You have common_circle_image XML file for RecyclerView item and the generated class is CommonCircleImageBinding so like this you use the onCreateViewHolder to pass the generated binding class to the ViewHolder class

@NonNull
@Override
public CategoryAdapter.MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    CommonCircleImageBinding itemBinding = CommonCircleImageBinding .inflate(LayoutInflater.from(parent.getContext()), parent, false);
    return new MyViewHolder(itemBinding);
}

and use the holder class like this so you can use these fields in onBindViewHolder

static class MyViewHolder extends RecyclerView.ViewHolder {
    private TextView txt;
    private ImageView img; 

    MyViewHolder(CommonCircleImageBinding itemBinding) {
        super(itemBinding.getRoot());
        img = itemBinding.img ;
        txt = itemBinding.txt ;
    }
}
