How to get ID from dynamic View?

Question

Java

Hello everyone, in my application, elements are displayed dynamically on the screen, and I can also remove these dynamic elements. I need to somehow bind to the element being deleted, get an ID or getText, at least get something unique from the element being deleted.

MainActivity.java

package ru.test

import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    //Логи для отладки
    private static final String TAG = "myLogs";

    //счетчик чисто декоративный для визуального отображения edittext'ov
    private int counter = 0;

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

        Button addButton = (Button) findViewById(R.id.button);

        //находим наш linear который у нас под кнопкой add edittext в activity_main.xml
        final LinearLayout linear = (LinearLayout) findViewById(R.id.linear);
        addButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                counter++;

                //берем наш кастомный лейаут находим через него все наши кнопки и едит тексты,
                // задаем нужные данные
                final View view = getLayoutInflater().inflate(R.layout.custom, null);
                Button deleteField = (Button) view.findViewById(R.id.button2);
                EditText text = (EditText) view.findViewById(R.id.editTextCustom);
                text.setText("Some text" + counter);
                //добавляем елементы в linearlayout
                linear.addView(view);

                //Удаляем элемент
                deleteField.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        try {
                            //получаем родительский view и удаляем его
                            ((LinearLayout) view.getParent()).removeView(view);
                            Log.e(TAG, "Delete = "+ view.getId());
                        } catch (IndexOutOfBoundsException ex) {
                            ex.printStackTrace();
                        }
                    }
                });
            }
        });
    }
}
