button to be the same size in java code and xml

[goldfish10]

I have a button I created in Xml and that works great.
I am attempting to generate the same button in java code, but I am having trouble.
It seems the button height is larger than the the xml code.
I have tried the Button.setHeight, but it does not seem to have any affect.
Perhaps we need to Inflate the XML.
I have included the Xml and java code.
So, I would like get the java code to match the xml.

login2.xml code...
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
androidrientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:weightSum="1"
android:scrollbars="vertical"
android:scrollbarAlwaysDrawHorizontalTrack="true">

<LinearLayout android:id="@+id/LinearLayout3"
androidrientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:layout_marginLeft="4dp"
android:layout_marginBottom="4dp"
android:layout_marginRight="4dp" >
<TextView android:id="@+id/text_one"
android:text=""
android:textSize="8pt"
android:textColor="#000000"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="right"
android:layout_weight="5" />
<Button android:id="@+id/ButtonSubmit"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:background="@drawable/submit"
androidnClick="submitLogin2"
android:layout_weight="5" />
</LinearLayout>
</LinearLayout>


public void mySubmit() {
LinearLayout parent = new LinearLayout(this);
parent.setOrientation(LinearLayout.VERTICAL);

LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams (LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT, 0.9f);

LinearLayout child = new LinearLayout(this);
child.setOrientation(LinearLayout.HORIZONTAL);
child.setGravity(Gravity.RIGHT);
child.setPadding(162, 0, 0, 200);
Button b = new Button(this);
b.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT , LayoutParams.FILL_PARENT));
b.setHeight(5);
b.setBackgroundResource(R.drawable.submit);

child.addView(b, lp);
parent.addView(child);

this.setContentView(parent);

b.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showDialog(0);
t = new Thread() {
public void run() {
System.exit(0);
}
};
t.start();
}
});
return;
}

Figured it out... I was able to use just xml.
Thanks!
