Simple way to change text size in layout

Question

I have RelativeLayout with RelativeLayout title bar:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="vertical" >

<RelativeLayout android:id="@+id/titleBar"
    style="@style/TitleBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true">

<TextView
    android:id="@+id/caption"
    style="@style/WindowCaption"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:text="caption"/>

<Button
    android:id="@+id/buttonSave"
    style="@style/ButtonBar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:layout_marginRight="5dp"
    android:onClick="save"
    android:text="Save" />

</RelativeLayout>
...
</RelativeLayout>

On a small screens the button gets on top of the text:

I want to resize text, or button to make all of them properly visible. And I want the text was is on the centre.

Can I do it somehow using only style and layout tools?

Or the only way is to programmatically change the text size?
