Trying to programatically position an image

[Chuck Jagger]

I've been trying to programatically position an image. I've got the XML working, and can do it in the XML, but I can't seem to make it work in the code. The program runs just fine, but just keeps putting the diamond in the upper left hand corner of the screen. What am I doing wrong?

 
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
<ImageView android:id="@+id/thermo"
	android:layout_width="wrap_content"
	android:layout_height="wrap_content"
	android:layout_gravity="left"
	android:layout_marginTop="24px"
	android:layout_marginLeft="34px"
	android:src="@drawable/thermo" />
	
<ImageView android:id="@+id/diamond"
	android:layout_width="wrap_content"
	android:layout_height="wrap_content"
	android:layout_gravity="left"
	android:layout_marginTop="75px"
	android:layout_marginLeft="121px"
	android:src="@drawable/reddiamond" 
	/>	 
	 
</FrameLayout>

        setContentView(R.layout.main);
        
        //* X base is 121px (-40F)

        ImageView image = (ImageView) findViewById(R.id.diamond);

        
        //* FrameLayout.LayoutParams fp = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.FILL_PARENT, FrameLayout.LayoutParams.FILL_PARENT);
        MarginLayoutParams mp = new MarginLayoutParams(image.getLayoutParams());
        left = rightpic + 150;
        top = toppic + 58;
        right = left + 21;
        bottom = top + 21;
        Toast.makeText(this,"left="+Integer.toString(left)+" top="+Integer.toString(top)+" right="+Integer.toString(right)+" bottom="+Integer.toString(bottom),Toast.LENGTH_LONG).show();
        mp.setMargins(left, top, right, bottom);
        FrameLayout.LayoutParams fp = new LayoutParams(mp);
        image.setLayoutParams(fp);
/** 
		ImageView hand = (ImageView)rlRoot.findViewById(R.id.ivHandAnimation);

        MarginLayoutParams marginsParams = new MarginLayoutParams(hand.getLayoutParams());
        marginsParams.setMargins(this.getLeft(), rlRoot.getMeasuredHeight() - 20, 0, 0);
        RelativeLayout.LayoutParams lp = new LayoutParams(marginsParams);
        //lp.height = rlRoot.findViewById(R.id.btnHole_14).getMeasuredHeight();
        hand.setLayoutParams(lp);
