iPhone section index for android?!

Question

I need some examples or tutorial, how to implement iPhone side index for Android.

I read already this topic (http://stackoverflow.com/questions/1201962/android-equivalent-to-iphone-indexed-uitableview) and I'm trying AlphabetIndexer, but:

• How do I create it properl at all?
• How can be AlphabetIndexer displayed?!
• Is an extra layout schema for indexed lists already defined?

UPD:

If you downvote the topic, could you at least argue, why.

Thank you

Ps. I give you a bit of my code:

static String[] COUNTRIES = new String[] {"Ammensdorf", "Afghanistan", "Albania" ..};
static List<String> countryList = Arrays.asList(COUNTRIES);

public void onCreate(Bundle savedInstanceState) 
{       
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ListView lv1=(ListView)findViewById(R.id.ListView01);
        // By using setAdpater method in listview we an add string array in list.
        // lv1.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , COUNTRIES));

        Cursor c1 = createCursor(COUNTRIES);
        MyAdapter sortedAdapter = new MyAdapter(this, R.layout.list_item_extended, c1, new String[] {"country"},
            new int[] {R.id.list_item_extended});
        lv1.setAdapter(sortedAdapter);
}

private Cursor createCursor(String[] listData) 
{        
    MatrixCursor matrixCursor = null; 
    String[] menuCols = new String[] {"_id", "country"};
    matrixCursor = new MatrixCursor(menuCols);

    int i = -1;
    Object[] tmpArr = new Object[2];
    String tmpLetter = null;
    String currentLetter = null;
    for (String country: countryList)
    {
        currentLetter = country.substring(0, 1);
        if (!currentLetter.equals(tmpLetter))
        {
            tmpLetter = currentLetter;
            i++;
        }
            tmpArr[0] = i;
        tmpArr[1] = country;
        matrixCursor.addRow(tmpArr);
    }

    return matrixCursor;
}

private static class MyAdapter extends SimpleCursorAdapter implements SectionIndexer 
{
    private AlphabetIndexer mIndexer;

    public MyAdapter(Context context, int layout, Cursor c, String[] from, int[] to) 
    {
        super(context, layout, c, from, to);

        String alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
        mIndexer = new AlphabetIndexer(c, 0, alphabet);
    }

    public int getPositionForSection(int section) {
        return mIndexer.getPositionForSection(section);
    }

    public int getSectionForPosition(int position) {
        return mIndexer.getSectionForPosition(position);
    }

    public Object[] getSections() {
        return mIndexer.getSections();
    }
}
