That is what you need:

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="FOOBAR"
        android:id="@+id/textView2"
        android:textSize="30dp"
        android:textColor="#ffffffff" />
