alternating colors of spinner items

问题

Can I make the items to show up in alternating colors in spinner control

回答1:

Yes, you can. If you are following the Spinner Tutorial then you can subclass your adapter (passing a List of your items) to produce an alternating color effect:

ArrayAdapter<CharSequence> adapter =
        new ArrayAdapter(this, R.layout.simple_spinner_item, myList) {
    @Override
    public View getDropDownView(int position, View convertView, ViewGroup parent) {
        View view = super.getDropDownView(position, convertView, parent);
        if (position % 2 == 0) { // we're on an even row
            view.setBackgroundColor(evenColor);
        } else {
            view.setBackgroundColor(oddColor);
        }
        return view;
    }
}

If you're already defining your own adapter and implementing getDropDownView then you can add something like the above to the end of your method.

Edit - updated with slund's advice. Thank you!

You can create a custom adapter and change the color of each item. Look at this link for more details.
