code: public static void fetchWidthAndHeight(ViewGroup.LayoutParams params, TypedArray array,
                                             int widthAttr, int heightAttr) {
          params.width = array.getLayoutDimension(widthAttr, 0);
          params.height = array.getLayoutDimension(heightAttr, 0);
      }
docs: Helper method to be called from {@link ViewGroup.LayoutParams#setBaseAttributes} override
  that reads layout_width and layout_height attribute values without throwing an exception if
  they aren't present.
