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