How to set `ImageView`'s height to match it's width while `layout_weight` is set?

public class SquareLinearLayout extends LinearLayout {
public SquareLinearLayout(Context context) {
    super(context);
}

public SquareLinearLayout(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public SquareLinearLayout(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

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

    int width = MeasureSpec.getSize(widthMeasureSpec);
    int height = MeasureSpec.getSize(heightMeasureSpec);
    int widthDesc = MeasureSpec.getMode(widthMeasureSpec);
    int heightDesc = MeasureSpec.getMode(heightMeasureSpec);
    int size = 0;
    if (widthDesc == MeasureSpec.UNSPECIFIED
            && heightDesc == MeasureSpec.UNSPECIFIED) {
        size = getContext().getResources().getDimensionPixelSize(R.dimen.default_size); // Use your own default size, for example 125dp
    } else if ((widthDesc == MeasureSpec.UNSPECIFIED || heightDesc == MeasureSpec.UNSPECIFIED)
            && !(widthDesc == MeasureSpec.UNSPECIFIED && heightDesc == MeasureSpec.UNSPECIFIED)) {
        //Only one of the dimensions has been specified so we choose the dimension that has a value (in the case of unspecified, the value assigned is 0)
        size = width > height ? width : height;
    } else {
        //In all other cases both dimensions have been specified so we choose the smaller of the two
        size = width > height ? height : width;
    }
    setMeasuredDimension(size, size);
 }
}
