Getting error while setting a data into recycler view

I am getting 2 data from firebase and setting them in a card view in recycler view they are
name
nodename
there is no problem with the "name" data but my "nodename" data is not being set in the text view
the error message that I am getting
No setter/field for node found on class com.Loopchat.com.Mychats_Model
my model class
package com.Loopchat.com;
public class Mychats_Model {
public Mychats_Model(String name, String nodename) {
this.name = name;
this.nodename = nodename;
}
Mychats_Model(){
}
String name, nodename;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getNodename() {
return nodename;
}
public void setNodename(String nodename) {
this.nodename = nodename;
}
}
this is my Firebase data base structure

App crashes on attaching fetched data from Retrofit to adapter

I am working with Retrofit. I followed a tutorial and did exactly what he said. Response is working perfectly in a single TextView but not in RecyclerView. When I added an adapter class, it start crashing. I read logcat file too but didn't seem helpful. The app crashes without showing any error or exception.
Here is my main XML class with a RecyclerView.
<?xml version="1.0" encoding="utf-8"?>

My main class is working fine with a for loop to print data in one TextView but not for adapter or RecyclerView.

}
}
#Override
public void onFailure(Call<List<jsonData>> call, Throwable t) {
Toast.makeText(MainActivity.this,t.getMessage(),Toast.LENGTH_LONG).show();
}
});
}
}
SingleRow design XML class (single.xml) is as follows:
<?xml version="1.0" encoding="utf-8"?>
<com.google.android.material.card.MaterialCardView xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="title"

</LinearLayout>
</com.google.android.material.card.MaterialCardView>
Adapter class (adapter.java) for fetching data is as follows:
package com.example.apipractice;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.TextView;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
import java.util.List;
public class adapter extends RecyclerView.Adapter<adapter.myviewholder> {
List<jsonData> data;
public adapter(List<jsonData> data){
this.data = data;
}
#Override
public myviewholder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.single,parent,false );
return new myviewholder(v);
}
#Override
public void onBindViewHolder(#NonNull adapter.myviewholder holder, int position) {
holder.t1.setText((int) data.get(position).getId());
holder.t2.setText( data.get(position).getTitle());
}
#Override
public int getItemCount() {
return data.size();
}
public class myviewholder extends RecyclerView.ViewHolder
{
TextView t1,t2;
public myviewholder(#NonNull View itemView) {
super(itemView);
t1= itemView.findViewById(R.id.t1);
t2 = itemView.findViewById(R.id.t2);
}
}
}
The following class is for retrofit instance, retrofitInstance.java:
package com.example.apipractice;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
public class retrofitInstance {
private static Retrofit retrofit;
private static final String commonURL = "https://jsonplaceholder.typicode.com";
public static Retrofit getRetrofit() {
if(retrofit ==null) {
retrofit = new Retrofit.Builder().baseUrl(commonURL).addConverterFactory(GsonConverterFactory.create()).build();
}
return retrofit;
}
}
This interface class (apiInterfce.java) is for the API get call:
package com.example.apipractice;
import java.util.List;
import retrofit2.Call;
import retrofit2.http.GET;
public interface apiInterface {
#GET("/posts?type=json")
Call<List<jsonData>> getdata();
}
My model class, jsonData.java:
package com.example.apipractice;
public class jsonData {
private float userId;
private float id;
private String title;
private String body;
// Getter Methods
public float getUserId() {
return userId;
}
public float getId() {
return id;
}
public String getTitle() {
return title;
}
public String getBody() {
return body;
}
// Setter Methods
public void setUserId(float userId) {
this.userId = userId;
}
public void setId(float id) {
this.id = id;
}
public void setTitle(String title) {
this.title = title;
}
public void setBody(String body) {
this.body = body;
}
}

Don't pass int value in setText() method. Because it consider int value as a resource id.
Please do as follow:
#Override
public void onBindViewHolder(#NonNull adapter.myviewholder holder, int position) {
holder.t1.setText(data.get(position).getId() + "");
holder.t2.setText( data.get(position).getTitle());
}

RecylerView does not list items in order when added dynamicly after 3rd item added

I have a button that says ADD ITEM.
Below there is a RECYCLERVIEW.
When you click on ADD ITEM it adds an EDITVIEW to the recycler view. You type text in it, and then click on ADD ITEM again and it adds another EDITVIEW to the recyler view.
Everything is in the right order.
When you click on ADD ITEM for the 4th time, instead of adding at the 4th position, it adds at the 1st position and moves the previous 3 items down 1.
What could be causing this?

Just try to replace your below snippet
myList.add(mLog);
mRecyclerAdapter.notifyData(myList);
etTitle.setText("");
Add this:
myList.add(mLog);
mRecyclerAdapter.addAll(myList);
mRecyclerAdapter.notifyDataSetChanged();
etTitle.setText("");

I would like to see your layout activity_main and recycler_view item because I have tried implementing your code with few twist and the code is working well please check the code below
https://github.com/muchbeer/StackOverflowRecyclerView
Please find the below Screen Shot
Kindy let me if this was your intended application

Expandable layout Expands upwards instead of downwards

When i try to put my Expandable layout to the bottom of my cardview using
android:layout_gravity="bottom" it goes to the bottom but expands upwards
After clicking the relative layout "button"
I am getting data from arraylist passing it to the recyclerview and cardview
i don't know if it's because of the Adapter animation settings or just fomr the xml

Custom Adapter not working for RecyclerView in a Fragment

I am working on an Android Project to display Github repo details.
I am trying to first select org name for a particular company, like Amazon has orgs on Github like AWS, AMZN, AWSLABS etc.
For this I first create a List of clickable buttons via RecyclerView(which works).
Then when user clicks on a particular org_name, the App does a HTTP request to Github to fetch relevant info and display inside a fragment which uses another RecyclerView(not working RecyclerViewRepoAdapter.java).
This part does not work as onCreateViewHolder or onBindViewHolder is not called (getItemCount is called and returns correct length)
Tried some of the suggestions mentioned like in this link! but it didn't work.
Any help is appreciated!

You are attaching adapter after getting a response from the API
LinearLayoutManager layoutManager = new LinearLayoutManager(getContext());
listAdapter = new RecyclerViewRepoAdapter(getContext(), repositories); // List of Github repos to be display
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(listAdapter); // Called from here after response from cloud funtion
Move this code in onCreateView
assert getArguments() != null;
View v = inflater.inflate(R.layout.fragment_github, container, false);
recyclerView = v.findViewById(R.id.repo_recycler_view);
LinearLayoutManager layoutManager = new LinearLayoutManager(getContext());
listAdapter = new RecyclerViewRepoAdapter(getContext(), repositories); // List of Github repos to be display
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(listAdapter); // Called from here after response from cloud funtion
return v;
And after getting a response from Api in AsyncTask onPostExecute() Method add data into list and notify adapter
ParseResponse parseResponse = new ParseResponse(response);
repositories = parseResponse.getRepositories();
listAdapter.notifyDataSetChanged();
