laya-coreui-es/build/es/layaAir/laya/ui/Radio.js

laya核心库、ui库es版本，剔除了媒体、TTF等功能。基于 LayaAir-release_2.12.0 修改

import { Event } from "../events/Event";
import { Button } from "./Button";
export class Radio extends Button {
    constructor(skin = null, label = "") {
        super(skin, label);
        this.toggle = false;
        this._autoSize = false;
    }
 destroy(destroyChild = true) {
        super.destroy(destroyChild);
        this._value = null;
    }
    preinitialize() {
        super.preinitialize();
        this.toggle = false;
        this._autoSize = false;
    }
    initialize() {
        super.initialize();
        this.createText();
        this._text.align = "left";
        this._text.valign = "top";
        this._text.width = 0;
        this.on(Event.CLICK, this, this.onClick);
    }
    onClick(e) {

    }
    set value(obj) {
