If you want to create a dialog which will look like as spinner dialog of single choice in android which will open in button click event than you can create a custom dialog. Sample code given below :-

You just have to call this method on click event.

public void showDialog() {
    CharSequence[] items = {"Red","Green","Blue" };
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setSingleChoiceItems(items, 0,
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();

                    }

                }
            });
    alert = builder.create();
    alert.show();
}
