Android : In Android get center of Relative Layout on API 10

I'm trying to find the center coordinates of a RelativeLayout that for the moment, is empty. I need to find the center before I can put anything into the Relative Layout. The Relative Layout is not the whole screen, so I can't use metrics to find the screen dimensions. Since my minimum API is 10, I can't use rLayout.getX() or rLayout.getY(). So what I've tried is:

int xScreenInt = gBoard_RL.getWidth()/2;
int yScreenInt = gBoard_RL.getHeight()/2;

int xInt = gBoard_RL.getLeft() + xScreenInt;
int yInt = gBoard_RL.getTop() + yScreenInt;

and all I get is 0,0. Does anyone have an any ideas how I can get this done? Here's my layout and the Activity so far:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/gb1_root_RL"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF"
tools:context=".GB1" >

<RelativeLayout
    android:id="@+id/gb1_topInfo_RL"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:background="@drawable/blu_grade_bg"
    android:orientation="vertical"
    android:paddingBottom="15dp" >

    <TextView
        android:id="@+id/gb1_scValue_TV"
        style="@style/mainScoreValueStyle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/gb1_score_TV"
        android:layout_marginLeft="10dp" />

    <TextView
        android:id="@+id/gb1_timeValue_TV"
        style="@style/mainTimeValueStyle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_below="@+id/gb1_time_TV"
        android:layout_marginRight="10dp" />
</RelativeLayout>

<RelativeLayout
    android:id="@+id/gb1_gf_RL"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/gb1_topInfo_RL"
    android:padding="10dp" >
</RelativeLayout>

the Relative Layout I need to find the center of is: android:id="@+id/gb1_gf_RL"

public class GB1 extends Activity {
TextView GScore_TV;

RelativeLayout gBoard_RL;
int xScreenInt, yScreenInt, xInt, yInt;
String xStr, yStr;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    overridePendingTransition(R.anim.cutin, R.anim.cutout);
    setContentView(R.layout.gb_layout);
    GScore_TV = (TextView) findViewById(R.id.G1_scoreValue_TV);
    gBoard_RL = (RelativeLayout) findViewById(R.id.gb1_gf_RL);


    gBoard_RL.setBackgroundColor(Color.MAGENTA);

    xScreenInt = gBoard_RL.getWidth()/2;
    yScreenInt = gBoard_RL.getHeight()/2;

    xInt = gBoard_RL.getLeft() + xScreenInt;
    yInt = gBoard_RL.getTop() + yScreenInt;

    xStr = String.valueOf(xInt);
    yStr = String.valueOf(yInt);
    GScore_TV.setText(xStr + ", " + yStr);
}

}
