question: @ Override public void onMeasure ( int widthMeasureSpec , int heightMeasureSpec ) { int measuredWidth = MeasureSpec . getSize ( widthMeasureSpec ) ; int widthMode = MeasureSpec . getMode ( widthMeasureSpec ) ; int measuredHeight = MeasureSpec . getSize ( heightMeasureSpec ) ; int heightMode = MeasureSpec . getMode ( heightMeasureSpec ) ; int minDimension = Math . min ( measuredWidth , measuredHeight ) ; super . onMeasure ( MeasureSpec . makeMeasureSpec ( minDimension , widthMode ) , MeasureSpec . makeMeasureSpec ( minDimension , heightMode ) ) ; }
target:  Measure the view to end up as a square, based on the minimum of the height and width.
