Change font size on actual Spinner button object

Question

I know it is possible to change the font size of the Spinner menu that pops up when the button is clicked, and I know it is possible to change the font size of an ordinary button - but I can't seem to find anything on changing the size of the text in the actual spinner button itself. Is this possible? If so, how can it be done?

Answer 1

This is the generic layout from simple_spinner_item.xml, I've added a textSize attribute at the bottom, let's save it as spinner_item.xml:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    style="?android:attr/spinnerItemStyle"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ellipsize="marquee"
    android:singleLine="true" 
    android:textSize="36sp" />

And you use it just like any other layout in an adapter:

Spinner spinner = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.spinner_item, list);
adapter.setDropDownViewResource(android.R.layout.spinner_dropdown_item);
spinner.setAdapter(adapter);
