Android: Comment faire pour Modifier la Taille du Texte dans ListView devenir plus grand?

Je suis brouillée avec la situation ci-dessous où j'ai créer un LinearLayout pour afficher une liste de contacts de mon téléphone. Mais, je ne peux pas figout où il m'est possible de définir le texte à l'intérieur de LinearLayout à devenir plus grand!S'il vous plaît aider, merci!!!!

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ListView android:layout_width="wrap_content"
              android:id="@+id/contactList"
              android:layout_height="0dp"
              android:padding="10dp"
              android:textSize="200sp"
              android:layout_weight="10"/>
    <CheckBox android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:id="@+id/showInvisible"
              android:text="@string/showInvisible"/>
    <Button android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/addContactButton"
            android:text="@string/addContactButtonLabel"/>
</LinearLayout>
