Answer 1

Here is the code, hope it'll be helpful for other users

private void fillData() {

    Cursor c = this.mDbManager.getNgOrderDetailByOrderNumber(this.mNumber);

    ArrayList < HashMap < String, String >> items = new ArrayList < HashMap < String, String >> ();

    if (!c.isAfterLast()) {
        do {
            // ... filling HashMap and putting it to ArrayList
        } while (c.moveToNext());
    }

    SimpleAdapter adapter = new SimpleAdapter(this, items, R.layout.list_item,
        new String[] {
        "product", "ordered", "price", "discount"
    },
        new int[] {
        R.id.ProductTextView, R.id.OrderedTextView,
        R.id.PriceTextView, R.id.DiscountTextView
    }) {

        // here is the method you need to override, to achieve colorful list

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {

            View view = super.getView(position, convertView, parent);

            HashMap < String, String > items = (HashMap < String, String > ) getListView()
                .getItemAtPosition(position);
            if (Long.parseLong(items.get("id")) % 10 == 0) {
                view.setBackgroundColor(Color.GREEN);
            } else {
                view.setBackgroundColor(Color.YELLOW);
            }
            return view;
        }

    };
    ListView l = (ListView) findViewById(android.R.id.list);
    l.setAdapter(adapter);
}
