Question

I’m trying to build an AlertDialog using Builder. My dialog has to have multiple option the user can choose from. I found on android developers website that I can use builder.setItems(int, DialogInterface.onClickListener). my problem is that im trying to pass a List addresses instead of the int. I want the user to choose an option from the list of addresses. Here’s my code for illustration:

    private List<Address> addresses;

    protected void updateMap() {
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Pick an Address");

    builder.setItems(addresses, new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface arg0, int choosenAddress) {

            //address = addresses.get(choosenAddress); //choose result from the array

        }
    });

In the builder.setItems ..i get an error saying this argument does not take list.

SetItems takes Charsequence Array as a parameter, so you will have to convert List<Address> to List<String> and then use list.toarray()
