Is it possible to access a string-array item in Android?

snip-code from values/string.xml:

<array name="categories">
    <item name="today">Today</item>
    <item name="life">Life</item>
    <item name="corner">Corner</item>
    <item name="banks">Banks</item>
    <item name="it">IT</item>
    <item name="fun">Fun</item>
</array>

snip-code from layout/main.xml:

<Button
    android:id="@+id/today"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="8sp"
    android:text="@array/categories"
    />

Is it possible to assign a label-name to a Button with id=today directly from values/string.xml using string-array with name=categories and specific item, in this case - today?
