`widthMeasureSpec` is not what you think. It is not the width. — Vladyslav Matviienko, Dec 03 '18 at 07:47

public class CustomLinearLayout extends LinearLayout {

    private static final float RATIO = 0.5f;

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

    @Override
    protected void onMeasure(int widthSpec, int heightSpec) {
        int customHeight = MeasureSpec.makeMeasureSpec(
                            (int)(MeasureSpec.getSize(widthSpec) * RATIO), MeasureSpec.EXACTLY);
        super.onMeasure(widthSpec, customHeight);
    }
}
