onMeasure(): calculate and set your size

A view is expected to measure its size. Not aware of its position where it is in the layout hierarchy. Merely a method for its size!!

onLayout(): The position for this control

a view is called with its old and new positions! The view can further layout its children once it knows where itself is!!
