When overriding this method, you must call setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an exception, thrown by measure(int, int).

    Parameters

    • widthMeasureSpec: number

      horizontal space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.
