After measuring, get the width and height with the getMeasuredWidth() and getMeasuredHeight() methods, respectively.

Parameters:

widthMeasureSpec - The width MeasureSpec passed in your View.onMeasure() method

heightMeasureSpec - The height MeasureSpec passed in your View.onMeasure() method

aspectRatio - The aspect ratio to calculate measurements in respect to

getMeasuredWidth

public int getMeasuredWidth()

Get the width measured in the latest call to measure().

getMeasuredHeight

public int getMeasuredHeight()

Get the height measured in the latest call to measure().
