Android :: Programmatic UI - Setting IDs Of Some Elements

I need to add some parts of my UI programmatically. I'm doing this because I need to set the ids of some elements up in such a way that they can be easily access in a for loop. So far I have this xml:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/attr_row" android:layout_width="fill_parent"
android:layout_height="wrap_content"> <EditText android:id="@+id/attr_name"
android:hint="Attribute" android:layout_width="0dip" android:layout_weight="2"
android:layout_height="wrap_content" android:inputType="textPersonName" />
<EditText android:id="@+id/attr_val" android:hint="Value"
android:layout_width="0dip" android:layout_weight="3"
android:layout_height="wrap_content" android:inputType="textPersonName" />
<ImageButton android:id="@+id/drop_attr" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:background="@drawable/btn_delete_states"
android:layout_gravity="center_vertical" /> </LinearLayout>

At the moment, I inflate this xml five times like so:
for (int i = 0; i<5; i++) { LinearLayout attrList = (LinearLayout) findViewById (R.id.attr_list);
LayoutInflater inflater = getLayoutInflater();
View row = inflater.inflate(R.layout.attr_row, null);
LinearLayout extraAttr = (LinearLayout) row.findViewById (R.id.attr_row);
ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT);
attrList.addView(extraAttr, i, params); }

The link below shows two pictures - the layout hierarchy and the result in the emulator. http://picasaweb.google.com/bengoldcross/Android?authkey=Gv1sRgCJ785I...
As can be seen, the xml is inflated five times successfully but only one is actually displayed. Inspecting the hierarchy viewer a bit more explains why. The layout being displayed is at location x=0 y=111 all the others are being rendered at x=320 y=111. It would appear they are being displayed a) off screen and b) on top of each other. So, why are they and how do I stop it from happening?
