Android平台以Widget方式集成HTML5+SDK

                <li id="trace" class="mui-table-view-cell mui-media mui-col-xs-4 mui-col-sm-4">  
                    <a href="#">  
                        <span class="mui-icon iconfont icon-diandongche" style="color: #ea8010;"></span>  
                        <div class="mui-media-body">搜寻车辆</div>  
                    </a>  
                </li>

(function($, doc) {  
            $.init({  
                swipeBack:false //启用右滑关闭功能  
            });  

            $.plusReady(function() {  
                var settingPage = $.preload({  
                    'url':'../settings.html',  
                    'id': 'settings'  
                });  

// 省略部分  

                document.getElementById("trace").addEventListener("tap", function(e){  
                    alert("???");  
                    startARActivity();  
                });  
            });  

        }(mui, document));  

plusReady事件正常，document.getElementById("trace").addEventListener("tap", function(e)未能正常执行。
