Question

Could someone tell me what is wrong with this piece of code?

It is supposed to be a ListView from an XML file that is then referred to in Java.
Alas, it crashes my application every time it enters the Menu class.

public class Menu extends ListActivity {

    String Name_for_classes[] = {"- 1-9 Tabels -", "- 10-19 Tabels -", "- 20-29 Tabels -" };
    String Tabel_classes[] = {"First", "Second", "Third"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setListAdapter(new ArrayAdapter<String>(this, R.layout.menu, Name_for_classes));
        ListView list = getListView();
        list.setTextFilterEnabled(true);
    }
}

Okay, let’s assume you have your ListView in an XML file called my_listview.xml.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.my_listview.xml);
    ListView list = (ListView)findViewById(R.id.list);
    ArrayAdapter<String> yourAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, Name_for_classes);
    list.setAdapter(yourAdapter);
}
