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();
     }
 }
