我需要一段android代码，要用到List view和spinner，这段代码可以让用户填写自己的个人信息，最后弹窗展示

以下是一段android代码，使用了List view和Spinner，可以让用户填写自己的个人信息，并在最后弹窗展示：

MainActivity.java

import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.Spinner;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    private ListView listView;
    private ArrayAdapter<String> adapter;
    private String[] items = {"Name", "Age", "Gender", "Country"};
    private String[] values = {"", "", "", ""};
    private EditText editTextName;
    private EditText editTextAge;
    private Spinner spinnerGender;
    private ArrayAdapter<String> spinnerAdapter;
    private String[] genders = {"Male", "Female", "Other"};
    private Spinner spinnerCountry;
    private ArrayAdapter<String> countryAdapter;
    private String[] countries = {"China", "USA", "Canada", "UK", "France", "Germany"};

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

        listView = findViewById(R.id.listView);
        adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, items);
        listView.setAdapter(adapter);

        editTextName = new EditText(this);
        editTextName.setHint("Name");
        editTextName.setMaxLines(1);

        editTextAge = new EditText(this);
        editTextAge.setHint("Age");
        editTextAge.setMaxLines(1);

        spinnerGender = new Spinner(this);
        spinnerAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, genders);
        spinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinnerGender.setAdapter(spinnerAdapter);

        spinnerCountry = new Spinner(this);
        countryAdapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_item, countries);
        countryAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinnerCountry.setAdapter(countryAdapter);

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                switch (position) {
                    case 0:
                        showDialog(editTextName, position);
                        break;
                    case 1:
                        showDialog(editTextAge, position);
                        break;
                    case 2:
                        showDialog(spinnerGender, position);
                        break;
                    case 3:
                        showDialog(spinnerCountry, position);
                        break;
                }
            }
        });
    }

    private void showDialog(final View view, final int position) {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle(items[position]);
        builder.setView(view);
        builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                switch (position) {
                    case 0:
                        values[position] = editTextName.getText().toString();
                        break;
                    case 1:
                        values[position] = editTextAge.getText().toString();
                        break;
                    case 2:
                        values[position] = spinnerGender.getSelectedItem().toString();
                        break;
                    case 3:
                        values[position] = spinnerCountry.getSelectedItem().toString();
                        break;
                }
                Log.d("MainActivity", "Values: " + values[0] + " " + values[1] + " " + values[2] + " " + values[3]);
            }
        });
        builder.setNegativeButton("Cancel", null);
        builder.show();
    }

    public void showResult(View view) {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Personal Information");
        builder.setMessage("Name: " + values[0] + "\nAge: " + values[1] + "\nGender: " + values[2] + "\nCountry: " + values[3]);
        builder.setPositiveButton("OK", null);
        builder.show();
    }
}

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.listview.MainActivit">
    
    <ListView
        android:id="@+id/listView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/button"
        android:layout_alignParentTop="true"
        android:dividerHeight="1dp" />

    <Button
        android:id="@+id/button"

        android:layout_alignParentBottom="true"
