Solution 1:

I've edited your code a bit. You need to create one ListView element in your layout XML file, and then in your Java file, find it using findViewById:

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class List extends Activity {

    String[] elements = { … };  // (omitted for better legibility)

    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);

        setContentView(R.layout.main); 
        ListView lv = (ListView)findViewById(R.id.ListView01);
        lv.setAdapter(new ArrayAdapter<String>(
                this, android.R.layout.simple_list_item_1, 
                elements));
    }

    public void onListItemClick(ListView parent, View v, int position,
                                 long id) {
        //if ("actinium".equals(elements[position]))
        //    {startActivity(Actinium.class);}
        //else if ("aluminum".equals(elements[position]))
        //    {startActivity(Aluminum.class);}
    }
}
