AbsoluteLayout in Android (XML)

AbsoluteLayout is the layout that you may want if you want to specify the x and y, in html its position:absolute, and the x(top) and y(left) is android:layout_x and android:layout_y. By looking at this, you can see that there are 5 possible value. Yet in our example i'm going to give you 4 coz i cant successful run the 5th one.
<?xml version="1.0" encoding="utf-8"?>
<AbsoluteLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
>
  <Button android:id="@+id/pixelsBtn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Pixels"

  <Button android:id="@+id/scaledBtn"
