  • How to update from populaeViewHolder to onBindViewHolder and onCreateViewHolder

    The latest Android Studio Firebase doesn't agree with populateViewHolder rather makes use onBindViewHolder and onCreateViewHolder. The difference is not much just follow the rules 


    1. Use FirebaseRecyclerAdapter<UserModel, UserListViewHolder> adapter = new FirebaseRecyclerAdapter<UserModel, UserListViewHolder>(
    mDatabaseReference) in both.

    In populateViewHolder we inflate the layout under Firebase declaration but in the other we use onCreateViewHolder to inflate View view = LayoutInflater.from(parent.getContext())
    .inflate(R.layout.user_layout, parent, false);

    FirebaseRecyclerAdapter<UserModel, UserListViewHolder> adapter = new FirebaseRecyclerAdapter<UserModel, UserListViewHolder>
    mDatabaseReference) { 

     public void populateViewHolder(UserListViewHolder userListViewHolder, UserModel UserModel, int position) 
     mUserList.setAdapter(adapter); }

    onBindViewHolder and onCreateViewHolder

    FirebaseRecyclerOptions<User> options = new FirebaseRecyclerOptions.Builder<User>()
    .setQuery(counterRef, User.class)
    adapter = new FirebaseRecyclerAdapter<User, ListOnlineViewHolder>(options) {

    protected void onBindViewHolder(@NonNull ListOnlineViewHolder listOnlineViewHolder, int i, @NonNull User model) {


    public ListOnlineViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext())
    .inflate(R.layout.user_layout, parent, false);

    return new ListOnlineViewHolder(view);
