Android : Setup Images Position In Absolute Layout?

I have an image setup inside an absolute panel.I am trying to set it's position via code.But I do not see any applicable method/property to set its position.

Here is my layout.

<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
>

<ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/marker" android:src="@drawable/marker" android:layout_y="106dp" android:layout_x="290dp"></ImageView>
</AbsoluteLayout>

Here is my code to set its position...
