Make layout width equal height?

Question

I want to have an ImageView with width=fill_parent, and the height should be whatever the width is. I'm not sure if there's a way to specify that in xml, is the only option to create my own ImageView-derived class?:

public class MyImageView extends ImageView {

    // Just return whatever the current width is?
    private int measureHeight(int measureSpec) {
        return getWidth();
    }
}

Is this the way to go, any other options? (I'm not sure if the above is even correct, not sure if the width measurement even takes place before the height measurement for example)

Thanks

Answer 1

You can get the width with the method

imageView.getMeasuredWidth();

So, you can set it's height

imageView.setLayoutParams(new LayoutParams(imageView.getMeasuredWidth(), imageView.getMeasuredWidth()));
