If you are using by default Spinner UI item adapter then you can't. You have to use Custom spinner. — Piyush

Create a custom spinner Adapter and then use the getDropDownView() method.

eg:

adapter = new ArrayAdapter<String>(ActivityName.this,
            R.layout.custom_spinner, gender_arraylist) {

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            View v = super.getView(position, convertView, parent);


            return v;
        }

        public View getDropDownView(int position, View convertView,
                ViewGroup parent) {
            View v = super.getDropDownView(position, convertView, parent);
            //change height and width or text size and colour here

            return v;
        }
    };

//it will help you to achieve this

genderAdapter = new ArrayAdapter<String>(context,
            R.layout.my_spinner_style, subjectList) {
        public View getView(int position, View convertView, ViewGroup parent) {
            View v = super.getView(position, convertView, parent);

            Typeface externalFont = Typeface.createFromAsset(getAssets(),
                    "ArchitectsDaughter.ttf");
            ((TextView) v).setTypeface(externalFont);

            return v;
        }

        public View getDropDownView(int position, View convertView,
                ViewGroup parent) {
            View v = super.getDropDownView(position, convertView, parent);

            Typeface externalFont = Typeface.createFromAsset(getAssets(),
                    "ArchitectsDaughter.ttf");
            ((TextView) v).setTypeface(externalFont);
            v.setBackgroundColor(Color.GRAY);
            ((TextView) v).setTextColor(Color.parseColor("#FFFFFF"));
            return v;
        }

//above code will help to give background color for dropdown spinner and to customize the font . width of drop down depends on width of spinner.Below is the my_spinner_style.xml for customizing text

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+android:id/text1"
style="?android:attr/spinnerItemStyle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:singleLine="true"
android:textColor="#ffffff" />
