Android的Databinding-RecyleView绑定

public class UserAdapter extends RecyclerView.Adapter<UserAdapter.UserHolder> {
    private static final int USER_COUNT = 10;

    @NonNull
    private List<User> mUsers;

    public UserAdapter() {
        mUsers = new ArrayList<>(10);
        for (int i = 0; i < USER_COUNT; i ++) {
            User user = new User(Randoms.nextFirstName(), Randoms.nextLastName());
            mUsers.add(user);
        }
    }

    public static class UserHolder extends RecyclerView.ViewHolder {
        private UserItemBinding mBinding;

        public UserHolder(View itemView) {
            super(itemView);
            mBinding = DataBindingUtil.bind(itemView);
        }

        public void bind(@NonNull User user) {
            mBinding.setUser(user);
        }
    }

    @Override
    public UserHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View itemView = LayoutInflater.from(viewGroup.getContext())
                .inflate(R.layout.user_item, viewGroup, false);
        return new UserHolder(itemView);
    }

    @Override
    public void onBindViewHolder(UserHolder holder, int position) {
        holder.bind(mUsers.get(position));
    }

    @Override
    public int getItemCount() {
        return mUsers.size();
    }
}
