Question

Hello!
I need to set the height of a component to be five times smaller than the width. Is it possible to do this in xml markup?
Thanks in advance!

Answer 1

Make your own component, an example for a square ImageVIew, by analogy, set any ratio

ublic class SquareImageView  extends ImageView {

  ...

  @Override
  protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);

    int width = getMeasuredWidth();
    setMeasuredDimension(width, width);
  }

  ...

}
