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:

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

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

    // Declare variables
    private ListView listView;
    private Button addButton;

    private ArrayList<Integer> intList = new ArrayList<Integer>();
    private ArrayList<String> stringList = new ArrayList<String>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        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
        final ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, stringList);
        listView.setAdapter(adapter);

        // Add items to ArrayList when button is clicked
        addButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                intList.add(1);
                stringList.add("Item " + intList.size());
                adapter.notifyDataSetChanged();
            }
        });
    }
}
``` 
In this code, we first import the necessary classes and define our variables. 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.

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