How to change text size of an Android Spinner element

I refer to the spinner in a java file by setting its input, which is a string array that has a name in the USA. I want to give my own size to the selected state in a spinner? How to specify its custom size?

This is the code:

Spinner state = (Spinner) findViewById(R.id.state);
            ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
                    this, R.array.state, android.R.layout.simple_spinner_item);
            adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            state.setAdapter(adapter);

Xml:

<Spinner
android:id="@+id/state"
android:layout_width="wrap_content"
android:layout_height="60dip"
android:layout_marginLeft="10dip"
android:addStatesFromChildren="true" >
</Spinner>

String array to display in Spinner:

<string-array name="state">

        <item>Select State</item>
        <item>Alabama</item>
        <item>Alaska</item>
        <item>American Samoa</item>

you can use

adapter.setDropDownViewResource(android.R.layout.simple_list_item_1);

or you can give it your layout:

adapter.setDropDownViewResource(R.layout.my_layout);

and your my_layout.xml should look like this:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+android:id/text1" android:layout_marginTop="5dp"
        android:layout_marginBottom="5dp" android:padding="3dp"
        android:layout_width="fill_parent" android:layout_height="wrap_content"
        android:gravity="center_horizontal"/>

Try using such an adapted adapter,

        ArrayAdapter<String> spinner_adapter = new ArrayAdapter<String>(getParent()
                .getApplicationContext(), R.layout.my_spinner_style,spinner_values) {

            public View getView(int position, View convertView, ViewGroup parent) {
                View v = super.getView(position, convertView, parent);
                ((TextView) v).setTextSize(18);

                return v;
            }

            public View getDropDownView(int position, View convertView,
                    ViewGroup parent) {
                View v = super.getDropDownView(position, convertView, parent);
                v.setBackgroundResource(R.drawable.spinner_drop_down);
                ((TextView) v).setTextColor(Color
                        .parseColor(config.sort_by_label_color));
                return v;
            }
        };

R.layout.my_spinner_style

<?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:paddingLeft="5dip"
android:singleLine="true"
android:textColor="#ffffff"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:ellipsize="marquee" />

And install this adapter on your counter,

        spinner.setAdapter(spinner_adapter);
