Recyclerview showing 0 items

Question

I have added items to RecyclerView and set adapter but it is showing zero elements. Means the list is empty. Please check and help me

ChatAdapter.java

public class ChatAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
  Context context;
  ArrayList<ChatModel> chatList;

  public ChatAdapter(Context context, ArrayList<ChatModel> chatList) {
    this.context = context;
    this.chatList = chatList;
  }

  @Override
  public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    return new TextInViewHolder(LayoutInflater.from(context).inflate(R.layout.chat_list_in_text, parent, false));
  }

  @Override
  public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {
    TextInViewHolder hold = (TextInViewHolder) holder;
    hold.tvIncText.setText(chatList.get(position).getText());

  }

  @Override
  public int getItemCount() {
    return 0;
  }

  public class TextInViewHolder {

    public TextInViewHolder(View itemView) {
        super(itemView);

    }
  }
}

"i knew someone would come by and say that" - yet you still answer it, creating duplicate content — Tim, Sep 26 '17 at 12:39
with due respect, i must say we can have a debate on this , frankly it's been a debate, people understand this when they are open to understand both sides but yet you are only advising me (you like me , i know , i too but as pals only) , i will be more careful , thanks — Pavneet_Singh, Sep 26 '17 at 12:45

Inside your getItemCunt you are returning 0

@Override
public int getItemCount() {
    return 0;
}

instead of returning 0 return list size which is chatList

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

Replace return 0 by return chatList.size();

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

@Override
public int getItemCount() {
   return chatList == null ? 0 : chatList.size();
}
