Dynamically displaying items in List View that is entered by User

I have two Edit Text, in which user enters their first name and surname. I want to display the names and surnames below in a list view. So, if users enters name and surname for the first time it should display in row 1 of list view, and for 2nd entry it should display in row 2 of the list veiw. My problem is that when I am doing a new entry, it replaces the text in the 1st row of list view and doesn't display in 2nd or next rows in list view.

Please see my code. It will be great if you can help me.

below is my Java code

    '''    package com.nitin.inflaterproject;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    ListView list;
    EditText editText1, editText2;
    LinearLayout linearLayoutMain;
    MyAdapter adapter;
    int counter;

    public void addData(View view){

        String text1 = editText1.getText().toString();
        String text2 = editText2.getText().toString();
        if(text1.equals("") || text2.equals("")){

            Toast.makeText(this, "Please enter required field", Toast.LENGTH_SHORT).show();
        }else{

            counter++;
            Toast.makeText(this, "Counter value is " + counter, Toast.LENGTH_SHORT).show();

                adapter = new MyAdapter(this, text1, text2,counter);
                list.setAdapter(adapter);
        }


    }


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        linearLayoutMain = (LinearLayout)findViewById(R.id.linearLayoutMain);
        editText1 = (EditText)findViewById(R.id.editText1);
        editText2 = (EditText)findViewById(R.id.editText2);
        list = (ListView)findViewById(R.id.listViewMain);
        counter = 0;



    }
}'''

And then Base Adapter Code

    MyList(String text1, String text2){

        this.text1 = text1;
        this.text2 = text2;

    }


}

class MyAdapter extends BaseAdapter {

    ArrayList<MyList> list;
    private Context context;
    private int count;
