Children of ListView doesn't respect parents border radius

Question

This is what I want to obtain (note - the blue is only hilited):

A ListView with rounded corners and children of it with with white-lightgrey background of every n-th.

This is my preview in AS:

And I have this MyArrayAdapter to paint every 2nd row in different color:

public class AlternateRowArrayAdapter extends ArrayAdapter
{
    private int[] colors;

    public AlternateRowArrayAdapter(@NonNull Context context, @LayoutRes int layout,
                                    @IdRes int textViewResourceId, @NonNull List<String> objects)
    {
        super(context, layout, textViewResourceId, objects);
        colors = new int[] {ResourcesCompat.getColor(context.getResources(), R.color.white, null) ,
                            ResourcesCompat.getColor(context.getResources(), R.color.lmsLightGrey, null)};
    }
    /**
     * Display rows in alternating colors
     */
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = super.getView(position, convertView, parent);
        int colorPos = position % colors.length;
        view.setBackgroundColor(colors[colorPos]);
        return view;
    }
}

Although the children of ListView doesnt respect the border radius of parent and put this background color to full rectangle of theirs:
How can I tell children to obey it's parent border radius?
