Android布局对齐textview和按钮

Question

I have attached the contents of an xml file. What I want to do is put the TextView in the center of the Row and the button aligned from the right. I have tried several solutions and yet I still haven't found the correct one. Any suggestions?

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <TableRow
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:stretchColumns="*">
        <TextView
            android:id="@+id/serviceTitle"
            android:textSize="20px"
            android:textStyle="bold"
            android:gravity="center_horizontal"/>
        <Button 
            android:layout_gravity="center_horizontal"
            android:id="@+id/testButton"
            android:background="@drawable/go_button">
        </Button>
    </TableRow>
    <ListView 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1" 
        android:id="@android:id/list">
     </ListView>
     <TextView android:id="@android:id/empty"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="Empty set"/>
</LinearLayout>
