You can change these settings in the layout file. The hello-spinner tutorial is very useful.

Add a new XML file to your layout folder.

Example: spinnerLayout.xml

<?xml version="1.0" encoding="utf-8"?>
    <TextView xmlns:android="http://schemas.android.com/apk/res/android"
              android:id="@+id/spinnerTarget"
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:textSize="14pt"         
              android:textColor="#FF8B1500"
              android:gravity="center"/>

Change the adapter resource to your new layout file:

adapter = ArrayAdapter.createFromResource(
                this, R.array.sound, R.layout.spinnerLayout);
