this is the way to do it:

VerticalFieldManager vv=new VerticalFieldManager(FOCUSABLE) {
    protected void paintBackground(Graphics g) {
    int prevColor = g.getColor();
    int bgColor;

    if (isFocus()) {
        bgColor = Color.Blue;
    } else {
        bgColor = Color.White;
    }

    g.setColor(bgColor);
    g.fillRoundRect(0, 0, getPreferredWidth(), getPreferredHeight(), 0, 0);
    g.setColor(prevColor);
}
    public void onFocus(int direction) {
    super.onFocus(direction);
    this.invalidate();
}
public void onUnfocus() {
    super.onUnfocus();
    this.invalidate();
}
};
_focusAnchor = new NullField(FOCUSABLE);
add(_focusAnchor);

You can try calling Field.setFocus on it, but since a manager is a container, I'm not sure you are going to see "the focus" over it.

If it doesn't work, you can try also overriding the paint method and draw your own custom focus when isFocus returns true.
