Programmatically position a button in relative layout

This is the layout XML I am using.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@color/tabTransparent"
    android:id="@+id/aLayoutRelative">

    <LinearLayout
        android:id="@+id/linearLayout8"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/linearLayout7"
        android:layout_below="@+id/linearLayout7"
        android:layout_marginTop="14dp" >

        <Button
            android:id="@+id/button5"
            style="?android:attr/buttonStyleSmall"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="@string/text_accounts_aHistoryNotes" />
    </LinearLayout>

</RelativeLayout>

I want to add the button programmatically in java source. This is what I tried.

RelativeLayout relativeLayout = (RelativeLayout)findViewById(R.id.aLayoutRelative);
LinearLayout lastLinearLayout = (LinearLayout)findViewById(R.id.linearLayout8);
lastLinearLayout.setOrientation(LinearLayout.HORIZONTAL);

LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.HORIZONTAL);
LayoutParams layoutParams = new LayoutParams(LayoutParams.FILL_PARENT,       LayoutParams.WRAP_CONTENT);
layoutParams.addRule(RelativeLayout.LEFT_OF, lastLinearLayout.getId());
layoutParams.addRule(RelativeLayout.BELOW, lastLinearLayout.getId());
layoutParams.setMargins(0, 14, 0, 0);
linearLayout.setLayoutParams(layoutParams);

Button button9 = new Button(this);
Log.i("tab0", recordTabs.get(0));
button9.setText(""+recordTabs.get(0));
button9.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
linearLayout.addView(button9);
relativeLayout.addView(linearLayout);

But in the view, the button is vertical with no text on it; aligned towards left of the page (in effect towards relative layout). XML version works well. I reckon the orientation settings turn out to be the culprit. Having googled in various documentations hardly helped.

Any thoughts?

Thanks in advance!

What are you trying to achieve?

for start, remove the 

layoutParams.addRule(RelativeLayout.LEFT_OF, lastLinearLayout.getId());

so you can at least see the button below.

Why to you place the buttons in linear layouts?
