Question

I have an arraylist and I want to use arrays.sort to sort them alphabetically, but when I run the app, the list is totally not sorted. I am not sure what’s wrong.

public class AList extends ListActivity {
    static String[] People = new String[] {
            "John Ken",
            "Albert Chan",
            "Kelvin McDonald"};

    public static void main(String[] args) {
    Arrays.sort(People);}


@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.activity_alist);
    setListAdapter(new ArrayAdapter<String>(this,
        android.R.layout.simple_list_item_1,
        People));

Answer 1

I don’t think your main method executes (Android has its own main method).

Try calling Arrays.sort() in your onCreate method instead.
