Sure, here's an example Android code to create an ArrayList of integers and strings, and display it in a ListView in the main activity using Kotlin:

First, create a new project in Android Studio and add the following code to the MainActivity.kt file:

```Kotlin
import android.os.Bundle
import android.view.View
import android.widget.ArrayAdapter
import android.widget.Button
import android.widget.ListView
import androidx.appcompat.app.AppCompatActivity

class MainActivity : AppCompatActivity() {

// Declare variables
private lateinit var listView: ListView
private lateinit var addButton: Button

private val intList = ArrayList<Int>()
private val stringList = ArrayList<String>()

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

    // Find UI elements
    listView = findViewById(R.id.list_view)
    addButton = findViewById(R.id.add_button)

    // Set up ListView adapter
    val adapter = ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, stringList)
    listView.adapter = adapter

    // Add items to ArrayList when button is clicked
    addButton.setOnClickListener {
        intList.add(1)
        stringList.add("Item ${intList.size}")
        adapter.notifyDataSetChanged()
    }
}
```

In this code, we first import the necessary classes and define our variables using the "lateinit" keyword to avoid initializing them in the constructor. We have a ListView for displaying the list, a Button for adding new items, and two ArrayLists: one for integers and one for strings.

In the onCreate method, we set the content view and find the ListView and Button UI elements. We then set up the ArrayAdapter for the ListView using the stringList ArrayList. We also set up an OnClickListener for the addButton that adds a new integer and string to the respective ArrayLists, updates the adapter, and increments the integer by 1 using string interpolation.

In the activity_main.xml layout file, we can add the following ListView and Button elements:

```xml
<ListView
 android:id="@+id/list_view"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:layout_marginTop="16dp"
 android:layout_marginBottom="16dp"
 android:divider="@android:color/black"
 android:dividerHeight="1dp"
 />

<Button
 android:id="@+id/add_button"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_gravity="center_horizontal"
 android:layout_marginTop="16dp"
 android:text="Add Item"
 />
```

This will create a ListView with a divider and a button centered below it.

When you run the app, you can click the button to add new items to the list, which will be displayed in the ListView.
