The second go occurs in layout(int, int, int, int) and is likewise leading-down. Through this move Each and every mum or dad is liable for positioning all of its young children using the measurements computed in the evaluate pass. Any time a view's measure() strategy returns, its getMeasuredWidth() and getMeasuredHeight() values should be set, in conjunction with Individuals for all of that view's descendants. A view's measured width and calculated peak values must regard the constraints imposed because of the view's moms and dads.
