Get text from dynamically added view

In the post "Add and Remove view dynamically", views are added dynamically ar run-time, with add and remove function. It's modified to have a "insert" button on each row, the associated text will be inserted in EditView if the button clicked.

package com.example.androiddynamicview;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.animation.LayoutTransition;
import android.app.Activity;
import android.content.Context;

public class MainActivity extends Activity {
 
 EditText textIn;
 Button buttonAdd;
 LinearLayout container;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  textIn = (EditText)findViewById(R.id.textin);
  buttonAdd = (Button)findViewById(R.id.add);
  container = (LinearLayout)findViewById(R.id.container);
  
  buttonAdd.setOnClickListener(new OnClickListener(){

   @Override
   public void onClick(View arg0) {
    LayoutInflater layoutInflater = 
      (LayoutInflater) getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    final View addView = layoutInflater.inflate(R.layout.row, null);
    final TextView textOut = (TextView)addView.findViewById(R.id.textout);
    textOut.setText(textIn.getText().toString());
    Button buttonRemove = (Button)addView.findViewById(R.id.remove);
    buttonRemove.setOnClickListener(new OnClickListener(){

     @Override
     public void onClick(View v) {
      ((LinearLayout)addView.getParent()).removeView(addView);
     }});
    
    Button buttonInsert = (Button)addView.findViewById(R.id.insert);
    buttonInsert.setOnClickListener(new OnClickListener(){

     @Override
     public void onClick(View v) {
      String text = textOut.getText().toString();
      String newText = textIn.getText().toString() + text;
      textIn.setText(newText);
     }});
    
    container.addView(addView, 0);
   }});
  
  LayoutTransition transition = new LayoutTransition();
  container.setLayoutTransition(transition);
 }
