user: make an android code to create a list with array list of int and strings to show in main activity

assistant: Sure, here's some sample code in Java to create an ArrayList of integers and strings, and display them in a list in the main activity:

```java
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;

import androidx.appcompat.app.AppCompatActivity;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

    private ListView listView;
    private ArrayList<Integer> intList;
    private ArrayList<String> strList;

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

        // Initialize ListView
        listView = findViewById(R.id.listView);

        // Initialize ArrayLists
        intList = new ArrayList<>();
        strList = new ArrayList<>();

        // Add items to ArrayLists
        intList.add(1);
        intList.add(2);
        intList.add(3);

        strList.add("Apple");
        strList.add("Banana");
        strList.add("Cherry");

        // Create ArrayAdapter to convert ArrayLists into ListView items
        ArrayAdapter<Integer> intAdapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, intList);
        ArrayAdapter<String> strAdapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, strList);

        // Set ListView adapter to show items
        listView.setAdapter(intAdapter); // Change to strAdapter to show strings instead of integers
    }
}
```

This code creates two ArrayLists, one containing integers and the other containing strings. It then adds some sample items to the ArrayLists. Next, it creates ArrayAdapters to convert the ArrayLists into ListView items, and sets the ListView adapter to display the integers or strings depending on which ArrayAdapter is used. Finally, the ListView is displayed in the main activity.

user: Would you be able to rewrite this in Kotlin for me?

assistant: Sure, here's the equivalent code in Kotlin:

```kotlin
mport android.os.Bundle
import android.widget.ArrayAdapter
import android.widget.ListView
import androidx.appcompat.app.AppCompatActivity

class MainActivity : AppCompatActivity() {
private lateinit var listView: ListView
private lateinit var intList: ArrayList<Int>
private lateinit var strList: ArrayList<String>

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    // Initialize ListView
    listView = findViewById(R.id.listView)

    // Initialize ArrayLists
    intList = ArrayList()
    strList = ArrayList()

    // Add items to ArrayLists
    intList.add(1)
    intList.add(2)
    intList.add(3)

    strList.add("Apple")
    strList.add("Banana")
    strList.add("Cherry")

    // Create ArrayAdapter to convert ArrayLists into ListView items
    val intAdapter = ArrayAdapter(this, android.R.layout.simple_list_item_1, intList)
    val strAdapter = ArrayAdapter(this, android.R.layout.simple_list_item_1, strList)

    // Set ListView adapter to show items
    listView.adapter = intAdapter // Change to strAdapter to show strings instead of integers
}
}
```

This Kotlin code is functionally identical to the Java code, but written in Kotlin syntax. It initializes the ListView and ArrayLists, adds sample items to them, creates ArrayAdapters, and sets the ListView adapter to display the integers or strings depending on which ArrayAdapter is used.
