Is there a more efficient way to make my ListView? Only been programming with Android for about 2 weeks

I'm extremely new to programming android and programming in general. Haven't learnt anything previous and was just interested in learning some android dev. Anyhow I'll paste my code, but I was wondering if there's a better and more efficient way to create what I'm doing, because it took my about 3 days to even work out how to create this as I couldn't find any tutorials on setting intents up with ListView items. Thanks for your help in advance :)

public class main extends ListActivity {

@Override
public void onCreate(Bundle saved开发者_StackOverflowInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


    String[] listitems = new String[] {"1","2","3","4","5"};

    this.setListAdapter(new ArrayAdapter<String>(this, R.layout.rowlayout,
            R.id.label, listitems));
}

//This is mainly the section I'm unsure about :)

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);

            switch (position){
            case 0:
                Intent second = new Intent(this, second.class);
                startActivity(second);
            }
            return;
}

}

The code is technically OK, but your onListItemClick() method implementation is somewhat unusual. A typical pattern when using ListView is to get the item you clicked on, and do something with it, or pass it to another activity. A simple example:

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);

    // get the item we clicked on
    String item = (String) this.getListAdapter().getItem(position);

    Intent second = new Intent(this, second.class);
    // add the clicked item to the intent, to pass it to the second activity
    second.putExtra("com.my.package.listItem", item);
    startActivity(second);
}
